The emergence of powerful hand held devices like cell phones, personal digital assistants (PDA), pagers coupled with the advancement of wireless communication system have paved the way for a variety of mobile computing and wireless networking technology recently. The history of wireless networking goes to early days Defense Advanced Research Projects Agency packet radio network. The advantage of wireless networking is its ability to support user mobility and has created a new breadth to problem solving in this domain, resulting in unpredictable resource requirement and uncertainty in network connectivity. Solutions to these problems have boosted the market for wireless services.Wireless ad hoc network is a collection of mobile devices forming a network without any supporting infrastructure or prior organization. Nodes in the network should be able to sense and discover with nearby nodes. Due to the limited transmission range of wireless network, multiple network "hops" may be needed for one node to another (source to destination or intermediate node) across the network. There are number of characteristics in wireless ad hoc networks, such as the dynamic network topology, limited bandwidth and energy constraint in the network. Mobile ad hoc network plays an important role in different applications such as military operations to provide communication between squads, in emergency cases in out-of-the-way places, in medical control etc.Routing protocols play a significant ...

Master's Thesis from the year 2012 in the subject Computer Science - Technical Computer Science, grade: 70%, Griffith College Dublin (Faculty of Computing ), course: MSC Computing , language: English, abstract: Modern wireless sensor network can be expanded into large geographical areas via cheap sensor devices which can sustain themselves itself with very a low power usage. The networking capability enables these sensor nodes to incorporate, collaborates, and coordinates with among each other , and this is a fundamental shift in the field of networks which differentiates sensor network nodes form other networks such as IP-datagram, Ad-Hoc and so on.Currently, routing in the wireless sensor network faces multiple challenges, such as new scalability, coverage, packet loss, interference, real-time audio and video real time streaming, harsh weather environments, energy constraints and so forth. Network routing can be called an amalgamation of routing protocol and routing algorithm. The job of the routing protocols is to provide a cohesive view of network nodes topology while routing algorithm provides the intelligence in terms of optimal path calculation.We set out to conduct a detailed study of routing protocols in a IP-datagram, wireless ad-hoc and sensor network, and also accomplished routing protocols comparison against the chosen network performance factor dropped packet ratio.Routing protocols play an important role in modern wireless communication networks.Routing pro...

Andre Perez Voice over LTE. EPS and IMS Networks

7994.77 руб.
Voice over LTE (Long Term Evolution) presents the mechanisms put in place in 4G mobile networks for the transportation of IP packets containing voice data and telephone signaling, as well as the technologies used to provide a telephone service in the IMS (IP Multimedia Sub-system) network. Despite the difficulty connected to the handover of the 4G network to the 2G/3G network, a telephone communication will not be established on the 4G network. This book analyzes the technologies that have been put in place, such as CSFB (Circuit Service FallBack), an interim solution that enables a mobile connected to the 4G network to receive an alert transmitted by the 2G/3G network. The book also goes on to develop the SIP (Session Information Protocol) on which the telephone signaling transferred by the 4G network is based, the IMS network that provides the service and defines the routing, the SRVCC (Single Radio Voice Call Continuity) mechanism that maintains communication and the TAS (Telephony Application Server) that supplies supplementary services. Contents 1. The EPS Network. 2. The LTE Interface. 3. The CSFB Function. 4. SIP and SDP Protocols. 5. The IMS Network. 6. Telephone Services. 7. The SRVCC Function. About the Authors André Perez is a consultant and teacher in networks and telecommunications. He works with industrialists and operators regarding architecture studies and leads training on the 4G and IMS networks for NEXCOM.
