Mobile ad hoc networks (MANETs) are temporary networks which are formed for a specific purpose. They are infrastructureless, autonomous and entirely distributed systems where different wireless mobile nodes are capable of arbitrary movement and power switching without breaking the network connectivity since it is physically possible. In these networks, nodes must operate both as hosts and as routers...
In Mobile Ad Hoc Networks (MANET), delays and bandwidth limitations of the wireless network system adversely affect the performance of the Voice over IP (VoIP). The calls setup time and the voice Quality of service (QoS) of VoIP calls depend on the routing protocol, the mobility model, and the number of hops between the call parties. Number of research efforts used to study the performance metrics...
In this paper, an evaluation of SIP signaling and voice QoS for SIP based VoIP using GSM voice codec system over IPv6 MANETs with Static, and Random mobility models. This evaluation study considered two types of reactive routing protocols, AODV and DSR. The study examined IPv4, IPv6, and Robust Header Compression (ROHC) as a compression/decompression system for IPv6 headers. The evaluation results...
Most of the Future Internet users will be wirelessly connected to IP clouds through different types of wireless networks. Thus, the number of applications and devices will be increased, and IPv6 insists to be applied. Voice over IP (VoIP) is one of the most popular Internet applications which provide real time voice communications between different parties and network systems. The Quality of Service...
Vehicular ad hoc networks (VANETs) have recently received considerable attention. In such networks, mobile nodes are spontaneous and uncoordinated associations of vehicles equipped with 802.11-based hardware, and change their positions dynamically. VANETs applications require data, voice and video transmission. However, Voice over IP (VoIP) may provide good services through VANETs platform. It may...
Due to the dynamically varying network topology ofad-hoc networks, the admitted quality of service suffers from frequent path breaks that require network re-establishment over new paths. Thus, rendering ad-hoc networks inappropriate for real-time interactive sessions, e.g., video or audio calls. TORA is a distributed, loop-free, multipath routing protocol for multi-hop networks which supports both...
