This study improves the neighbor discovery in VANETs and in doing so decreases the network overhead and increases performance AODV routing protocol. Since AODV is a part of reactive routing protocols, if a request is sent from the source, a link would be created to the destination.The neighbor discovery is created through HELLO message. The HELLO message is broadcasted to all nodes at a specific time and this happens through the use hello timer and is calculated by Hello _interval default value, Min Hello_ Interval and Max Hello_Interval multiplied random number. This STUDY aims at sending HELLO message and through considering the various conditions of the nodes (such as Up, Down and In_Repair), place the unsaved information in the routing table. This condition is not considered for the In repair mode because a node might be in repair mode in the ti but may not be in this mode at the ti+1. It might be arranged according to the up mode and this can cause a freshness and closer path. In order to solve this problem, a function was introduced which checks all node continually. If they are in an Up or In_Repair mode, the HELLO message packet is sent and ACK is received.

In this article I have conducted a performance study of DSDV, DSR, and AODV routing protocols in Mobile Ad-hoc Networks (MANETs). I have evaluated the effect of speed, TCP types, and maximum queue length on throughput and the effect of speed on number of packet drops.I have compared the performance of DSDV (Destination Sequenced Distance-Vector) from the Proactive family with the second type is AODV (Ad-hoc On-Demand Distance Vector) from the Reactive family. I used a detailed simulation model to demonstrate the performance characteristics of these protocols. By simulating we can argue that if delay is main criteria than DSDV can be my best choice but if reliability and throughput are main parameters for selection then AODV gives better results compared to others because its throughput and packet delivery ratio is best among others. While there are many other issues that need to be considered in analyzing the performance of ad-hoc networks, I believe that our work could provide intuition for future protocol selection and analysis in ad-hoc networks.

Ad hoc networks have a great importance in modernscientific and technological usage. Ad hoc networkdoes not need a topology,infrastructure and specialmanagement. Security limits its functionalityspecially in unsecured environment. This work comesto solve this problem by modifying one of the usedprotocols in ad hoc networks, which is Ad HocOn-demand Distance Victor(AODV) routing protocol thatdepends on finding route path just when need to. Thismodification has done by using some reserved bitsfrom Route Request(RREQ) packet to add securityfeature by selecting encryption algorithm to protectpayload data that is transferred between nodes ofcommunication by considering workload level at eachnode when selecting route path. In addition, thiswork presents a technique for distributing public keyto be used within RSA algorithm by adding a new partto RREQ packet. The performance of the standard andmodified AODV protocol also studied in this work byconsidering some parameters that affect ad hocnetwork performance, which are mobility and number ofnodes while communication process.

Vehicular Ad-Hoc Networks (VANETs) play a key role to develop Intelligent Transportation Systems (ITS) aiming to achieve road safety and to guaranty needs of drivers and passengers, in addition to improve the transportation productivity. One of the most important challenges of this kind of networks is the data routing between VANET nodes which should be routed with high level of Quality of Service (QoS) to ensure receiving messages in the time. Then, the driver can take the appropriate decision to improve the road safety. In the literature, there are several routing protocols for VANETs which are more or less reliable to reach safety requirements. In this book, we start by describing all VANET basic concepts such as VANET definition, VANET versus Mobile ad-Hoc Network (MANET), architectures, routing definition and steps, Quality of Service (QoS) for VANET Routing, Metrics of evaluation, Experimentation, and simulation of VANETs, mobility patterns of VANET etc. Moreover, different routing protocols for routing in VANETs will be described. We propose two main categories to be presented: classical routing and bio-inspired routing. Concerning classical VANET, main principles and all phases will be overviewed, as well as, their two sub-categories which are topological and geographical protocols. After that, we propose a new category called bio-inspired routing which is inspired by natural phenomenon such as Ant colony, Bee life, Genetic operators etc. We present also, some referential protocols as example of each category. In this book, we focus on the idea of how to apply bio-inspired principle into VANET routing to improve road safety, and to ensure QoS of vehicular applications.

This book includes a synthesis of some of our previsions research works. It presents firstly a study of interactions between two routing protocols (AODV, DSR) and two transport protocol versions (TCP New Reno, Vegas). After this study, we conduct some simulations to analyze the behavior of these protocols with different node mobility and network load values. The performance results of each protocol are examined to identify our own scenarios in order to evaluate our proposed solution for better interactions between these protocols. This solution is called CL-TCP (Cross Layer TCP). It is an adaptation of the TCP congestion control mechanism with some parameters provided by the routing layer (mobility nodes and the size of routing length). After the evaluation of CL-TCP, the results showed that it significantly improves the interactions between TCP Vegas and AODV protocols.

We use the simple and efficient mechanism to improve the performance of ad-hoc On-demand protocols. We use more than one path at a time but only one active route for destination. This approach reduces overhead of the route maintenance at the time of link failure. When path failure occurs there is other route is available to the destination. We use the RREQ packets and made more than one RREP packet for more than one route. We compare our ad-hoc on-demand protocol with other ad-hoc on-demand protocols like DSR, AOMDV and AODV. Our approach reduces the normalized routing load and Dropping ratio then other ad-hoc on-demand protocols. It also reduces the end to end delay than other ad-hoc on-demand protocols.

Significant advancements in Wireless Sensor Networks (WSNs) opens doors for wide implementation in real-time applications like Industrial Monitoring, Smart Cities development, Underwater monitoring operations, tracking objects and many more. Energy Efficient routing is regarded as the most challenging task. Sensor networks mostly operate in complex and dynamic environments and routing becomes tedious task to maintain as the network size increases. Lots of routing protocols- Reactive, Proactive and Hybrid are proposed by researchers but every protocol faces some limitations in terms of energy, routing, packet delivery ratio and security. Therefore, to overcome all the routing issues, the trend has shifted to Biological based Algorithms like Swarm Intelligence based techniques. Ant Colony Optimization based routing protocols have demonstrated exceptional results in terms of performance when applied to WSN routing.

Ad hoc mobile devices heavily depend on the performance of batteries. Optimizing the power consumption is a very crucial issue. To maximize the lifetime of mobile ad hoc network, the power consumption rate of each node must be reduced. In this paper we present a novel energy efficient routing algorithm based on mobile agents to deal with the routing mechanism in the energy-critical environments. A few mobile agents move in the network and communicate with each node. They collect the network information to build the global information matrix of nodes. The routing algorithm chooses a shortest path of all nodes in all possible routes. Additionally, we compare the performance of power-relation routing protocol DSR (Dynamic Source Routing)in simulation environment. The results show that the survivability of Ad Hoc network has been better because of less energy consumption when usingour improved DSR as compare to standard DSR protocol.

Recent advances in communication technology are enabling implementation of different types of network in various environments. One such network is Mobile Ad-Hoc Network (MANET). The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic which is done by several routing protocols. The design problem of such a routing protocol is not simple since an ad-hoc environment introduces new challenges that are not present in fixed networks. With the advent of the scenarios seeking infrastructure-less network with wireless nodes, security concerns have made the required personnel to mull over the MANET configuration using different protocols for various sized networks. This work is carried out to simulate the MANET using GloMoSim and to propose the enhancement in the quality of service by addressing the security concerns that loom on this specific network.The project discusses various categories of protocols proposed for the MANET, applications that are found out of this network, overview of the AODV protocol and most importantly the simulations that are carried out.

In this work, we introduce new path diversity schemes in order to provide robustness for both unicast and multicast video communi­cation applications over wireless ad hoc networks. We first propose a general architecture for multipath video streaming over wireless ad hoc networks. Then for the unicast case, we propose multipath strea­ming with two node-disjoint paths, which have minimum concurrent Packet Drop Probability (PDP) among all path pairs. This approach minimizes the probability of concurrent loss of all the descriptions, thus optimizing the worst case Multiple Description Coding (MDC) video quality over all times. Based on our path selection model, we propose a heuristic PDP aware multipath routing protocol. For the multicast case, we propose multiple tree video multicast with MDC. Specifically, we propose two distributed protocols, Serial Multiple Disjoint Tree Multicast Routing (Serial MDTMR) and Parallel Multiple Nearly-disjoint Trees Multicast Routing (Parallel MNTMR). We show video quality of proposed protocols are significantly higher than that of other protocols, through extensive NS simulations and actual experiments.

Due to the highly dynamic topology there are special demands for routing protocols. Many routing protocols for MANETs have been proposed.This paper deals with both a classification of MANET routing protocols and a review of the protocols AODV, OLSR, CBRP, FSR, ZRP and GPSR. Some results are presented, derived from the extended simulations that have been performed with the NS-2 network simulator, in order to compare the efficiency of the above protocols with respect to Paket Delivery Ratio, Average End-to-End Delay, Path Optimality and Throughput. Simulationresults show that in terms of Paket Delivery Ratio and Throughput most protocols perform worse in larger networks with many nodes than in smaller ones with less nodes.

Mobile Ad hoc Network (MANET) is a system of wireless mobile nodes that dynamically self-organize in arbitrary and temporary network topologies without communication infrastructure. This network may change rapidly and unpredictably. Application of ad hoc networks includes Academic Environment Applications, Health Care Applications, Military Applications, Bluetooth, and Personal Area Network. A service can be any tangible or intangible thing that can be useful for someone, a service can be a hardware service like a printer that can be used by a mobile device to print a file. Service discovery is defined by using one or two of Pull and Push Mechanisms. Security is a main challenge in MANETs. We propose a Secure Service Discovery Protocol for ad hoc networks (SPDPh). Simulation results of (SPDPh) and (PDP) using simulator (Ns-2) shows the extent of efficient secure service discovery protocol for ad hoc networks.

Random SALOHA and CSMA protocols that are used to access MAC in ad hoc networks are very small compared to the multiple and spontaneous use of the transmission channel. So they have low immunity to the problems of packet collisions. Indeed, the transmission time is the critical factor in the operation of such networks. The simulations demonstrate the positive impact of erasure codes on the throughput of the transmission in ad hoc networks. However, the network still suffers from the intermittency and volatility of its efficiency throughout its operation, and it switches quickly to the saturation zone. In this context, game theory has demonstrated his ability to lead the network to a more efficient equilibrium. This, we were led to propose our model code set that formalizes the behavior of nodes during transmission within SALOHA networks and CSMA respectively

Mobile ad hoc networks (MANETs) are created by the mobile computing devices on an ad hoc basis without any support provided by a pre-installed communications infrastructure. Along with their appealing properties, MANETs exhibit properties that hinder their realization. Topology dynamism and bandwidth limitations adversely affect the performance of MANETs routing protocols. Virtual backbone is proposed to facilitate routing, broadcasting, and establishing a dynamic infrastructure for distributed location databases. Minimizing the virtual backbone size produces a simpler abstracted topology of the MANET and allows for using shorter routes. In this book, a comprehensive study of MANETs routing and clustering algorithms is presented along with a simulation- based performance evaluation of the most renowned algorithms using the NS2 network simulator. This comparison focuses on the total costs incurred in terms of CDS size, running time, and signaling overhead generated during the CDS creation and maintenance phases. Moreover, the effects of mobility rates, network size, and mobility models on the performance of each algorithm are investigated.

Master's Thesis from the year 2013 in the subject Computer Science - IT-Security, grade: C, Lovely Professional University, Punjab (School Of Computer Science and Engineering), course: M.Tech(CSE), language: English, abstract: The rapid proliferation of Mobile ad hoc network has changed the landscape of network security. The recent DOS attacks on major Internet sites have shown us, no open computer network is immune from intrusions. The ad-hoc network is particularly vulnerable due to its features of open medium, dynamic changing topology and cooperative algorithms, lack of centralized monitoring and management point and lack of a clear line of defense. The traditional way of protecting networks with firewalls and encryption software is no longer sufficient and effective. There are many intrusion detection techniques have been developed on Ad hoc network but have been turned to be inapplicable in this new environment. Here we need to search for new architecture and mechanisms to protect Mobile Ad hoc network. In the above all technique of intrusion detection is applied on the only one layer and that is probably on routing layer. But here we apply this intrusion detection system in the MAC layer for the more security, efficiency and high speed compare to other technique those whose apply in the network layer.

The Vehicular ad-hoc network (VANET) is an important communication paradigm in modern-day transport systems for exchanging live messages regarding traffic congestion, weather conditions, road conditions, and targeted location-based advertisements to improve the driving comfort. In such environments, authentication and privacy are two important challenges that need to be addressed. There are many existing works to provide authentication and privacy in VANETs. However, most of the existing authentication schemes are suffering from high computational cost during authentication and high communication cost during secure key distribution to a group of vehicles. Moreover, in many existing schemes, there is no conditional tracking mechanism available to revoke the misbehaving vehicles from the VANET system.In order to overcome these issues, four new approaches have been developed in this research work: Firstly, a dual authentication scheme is developed to provide a high level of security on the vehicle side to effectively prevent the unauthorized vehicles entering into the VANET. Moreover, a dual group key management scheme is developed to efficiently distribute a group key to a group of users and to update such group keys during the users' join and leave operations. Secondly, in order to preserve the privacy of vehicle users, a computationally efficient privacy preserving anonymous authentication scheme (CPAV) is developed to anonymously authenticate the vehicle users based on t...

Security and privacy are among the growing concerns of a Vehicular Ad hoc Network (VANET) which requires a high degree of liability from its participants. In this dissertation, we address security, anonymity, and privacy challenges of VANETs in the light of the IEEE standards for vehicular communications. VANET provides a variety of road-safety and other applications through wireless devices installed in vehicles and roadside infrastructure. However, a vehicle must not be able to take advantage of its anonymity for any misbehavior like sending false messages or malicious updates to other vehicles or a roadside infrastructure. We use proxy signature, identity-based signature, and elliptic curve cryptosystems to provide authentication for infrastructure generated messages, and anonymous authentication for vehicle originated messages. Also, we investigate how some of the MAC-layer weaknesses may impair the security of a VANET. Our solutions are lightweight, bandwidth friendly and compatible to the current standards of vehicular communications.

Ad-hoc network has opened a new dimension in wireless networks. It allows wireless nodes to communicate with each other in the absence of centralised support. It does not follow any fixed infrastructure because of the mobility of nodes and multi-path propagations. Link instability and node mobility make routing a core issue in MANETs. A suitable and effective routing mechanism helps to extend the successful deployment of MANETs. In this book, we have studied details of TORA, LDR and ZRP routing protocols which are routing protocols on use in MANET. The effects on the routing efficiencies with a special focus on the pause time, scalability and node density using throughput, network load, end- to-end delay and packet delivery ratio as indices of performance evaluation for FTP traffic were observed by using OPNET 14.0 modular as simulation tool. Based on our observations from literature and empirical study conducted using OPNET, we have found that among the three protocols, no single protocol can successfully provide optimum efficiency in different MANET scenarios.

Over the last few years, Local Area Networks have been popular and successful at providing wireless broadband services. However, mobile users are not able to establish a seamless connection when moving to other networks. In addition, they also share frequencies with other electronic devices. Therefore, the actual network throughput is far less than theoretically maximum throughput. This book provides an introduction to the IEEE 802.11 networks and the design and implementation of MAC/PHY layer protocols, which are robust and effective in supporting mobility, maximum throughput, and QoS for multimedia applications in real world environments. It covers WLANs, ad hoc networks, vehicle-to-vehicle networks, and multimedia ad hoc networks with an implemented testbed.As you read this book, you should have a clear understanding of the IEEE 802.11 system and learn techniques for designing and implementing an advanced system for various types of wireless networks and applications that use the IEEE 802.11 system.

In this book, the problem of finding a path from asource to a destination node in a mesh of mobilewireless nodes is considered. One class of solutionsto this problem is based on the position-basedrouting paradigm, whereby the forwarding nodes relysolely on the knowledge of their geographicallocation (which can be established, e.g., via GPS),the location of their neighbors, and the location ofthe destination. This book proposes several newrandomized position-based algorithms for routing inmobile ad-hoc networks. The proposed algorithmsincorporate two heuristics: greedy aimed atminimizing the remaining distance of the packet tothe destination, and compass striving to minimize thepacket's deviation from the direction towards thedestination. Additionally, the routing decisions arerandomized - for improved flexibility and reliabilitycommunication. Experimental results obtained forvarious network topologies show that the deliveryrates of our randomized algorithms are significantlybetter than those attained by the deterministicvariants of the same heuristics.

Due to this fact they are very vulnerable to attacks. Adversaries do not have to pass different barriers like gateways or firewalls like in wired networks. Therefore different architectures for intrusion detection were developed. The contribution of this paper is to present different intrusion detection architectures, explains their behaviour and compare them. Furthermore it is shown how game theory can be used to improve performance of intrusion detection.

Research Paper (postgraduate) from the year 2007 in the subject Computer Science - Internet, New Technologies, grade: PG, VIT University (Net Research Labs), 26 entries in the bibliography, language: English, abstract: One of the major challenges faced by MANET researchers is the deployment of end-to-end quality-of-service support mechanisms for streaming media services over a group of MANET users. Group-oriented services over large, dynamically changing MANET networks has a big impact on the needs of streaming services communication in terms of mobility, quality of service (QoS) support and multicasting. In MANET networks, where such features are not embedded with its architecture, it is necessary to develop QoS multicasting strategies. The research work focuses on the basic building blocks of an mobile ad hoc group communication scheme, which achieves multicasting optimal QoS efficiency OptiQ by tracking resource availability in a node's neighborhood based on resource reservations, which announces the required QoS before each session initiation. The primary quality of service (QoS) issues such as required bandwidth, message delay, traffic type and hop count per route improves the efficiency of streaming services over ad-hoc network. Streaming services support voice, data and video traffic by assessing and adjusting for various levels of QoS. The performance analysis is performed on functional prototype of OptiQ in mobile / wireless ad-hoc network with emphasis on servic...

Mobile Ad hoc Networks (MANETs) are dynamic networks populated by mobile stations or mobile nodes (MNs). Specifically, MANETs consist of a collection of nodes randomly placed in a line (not necessarily straight). MANETs do appear in many real-world network applications such as a vehicular MANETs built along a highway in a city environment or people in a particular location. MNs in MANETs are usually laptops, PDAs or mobile phones. These devices may use Bluetooth and/or IEEE 802.11 (Wi-Fi) network interfaces and communicate in a decentralized manner. Mobility is a key feature of MANETs. Each node may work as a router and the network can dynamically change with time; when new nodes can join, and other nodes can leave the network. In this thesis, comparative results of the Queueing Mobility Model and mobility models such as random walk/Brownian model have been carried out via Matlab software simulation. The study investigates the impact of mobility prediction models on mobile nodes' parameters such as the speed, the arrival rate and the size of mobile nodes in a given area. The results have indicated that mobile nodes' arrival rates may have influence on MNs population.

This book explains Wireless Sensor Networks energy constraints of battery-powered sensor nodes necessitate energy-efficient communication. The major existing solutions are based on classical layered protocols approach, which leads to significant overhead. It is much more efficient to have a unified scheme which blends common protocol layer functionalities into a cross-layer module. In this paper, a efficient crosslayer protocol (XLP) is introduced, which achieves congestion control, data fragmentation, routing, and medium access control in a cross-layer fashion. Our approach combines medium access organization with routing. in a cross-layer simulation platform, the state-of-the- art layered and cross-layer protocols have been implemented along with XLP for performance evaluations. XLP significantly improves the communication performance and outperforms the traditional layered protocol architectures in terms of both network performance and implementation complexity.

Mobile Ad hoc Networks or MANETs are networks in which multiple nodes, each possessing a wireless transceiver, from a network among them via peer-to-peer communication. There has been significant research activity over the past 5-10 years into performance of such networks with the view to develop more efficient and robust communication protocols. However, the vast majority of the research has concentrated on either developing appropriate mobility models for node movement or on developing performance metrics. The channel itself has been ignored. Some previous work had been done using Rayleigh channel model and Log-Normal model. However this work is based on Ricean channel fading model, which have not done till date.In the current work a more realistic wireless channel model is considered. In particular, we will consider one of the most well known wireless channel models, Ricean fading channel model. In this documentation, effects on the performance of mobile ad hoc networks due to presence of fading in Ricean channel is done by simulating experiments on QualNet simulator and then analyzing them.

Doctoral Thesis / Dissertation from the year 2014 in the subject Engineering - Computer Engineering, grade: Sobresaliente Cum Laude, , language: English, abstract: In the past, people were focused on how to build efficient highways and roads. Over time, focus shifted to mechanical and automotive engineering, in the pursuit of building faster cars to surmount greater distances. Later on, electronics technology impacted the construction of cars, embedding them with sensors, advanced electronics, and communication devices, making cars more intelligent, efficient, and safe to drive on.The applications and advantages of using Vehicular Networks (VNs) for enhancing road safety and driving efficiency are diverse, which explains why research in this area has recently emerged. In this Thesis, we focus on Vehicular Adhoc Networks (VANETs), which are a particular subclass of Vehicular Networks, that involves a set of equipped vehicles communicating with each other via wireless antennas, without requiring the use of any infrastructure.In order to enhance the warning message dissemination process, usually necessary in VANET safety applications, we propose an adaptive broadcast dissemination scheme that automatically chooses the optimal broadcast depending on the complexity of the map and the instantaneous vehicle density in the area. Its main goal is to maximize the message delivery effectiveness, while generating a reduced number of messages, and thus, avoiding or mitigating broadcast st...

The present book deals with how to use the precious wireless resources that are usually wasted by under-utilization of networks. We have been particularly interested to all resources that can be used in an opportunistic fashion using different technologies. We have designed new schemes for better and more efficient use of wireless systems by providing mathematical frameworks. In this sense we focused on cognitive communication networks, where a cellular service provider can reserve a portion of its resources to secondary users or virtual suppliers. Delay tolerant networks are used as an alternative to the significant increase of the traffic load in cellular networks. In areas where the network infrastructure implementation is geographically difficult, the use of ad-hoc networks seems an appropriate solution. Indeed, we have developed a new analytical model of IEEE 802.11e used in this type of network protocol.

Deployment of wireless sensor networks is rapidly increasing day by day to monitor physical environments for critical everyday applications. The main challenge for wireless sensor networks is establishing a reliable and fault tolerant communication channel and able to respond quickly and efficiently to the base station. Usually large numbers of micro sensors are deployed and replacing the battery in many cases is not an option thus long system lifetimes are required. Standalone measures such as choosing low power micro sensors are not alone sufficient to achieve energy efficiency, also applications have various limitations depending upon their architecture which makes it further more exigent to design networks without degrading the performance. This book focuses on identifying the performance challenges based on the statistical data obtained by analysing traffic trends in OPNET Simulator and proposes an enhanced RREP packet for AODV to improve its performance.
