Multimedia Traffic Over MANETs: Evaluation and Performance Analysis

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 131)

Abstract

Providing required QoS guarantees in wireless mobile ad-hoc networks (MANETs) is much more challenging than in wired networks. This is mainly due to its characteristics such as frequently changing topology, un-centralized control, interference, multi-hop routing and collisions due to contention for channel access. Efficient and reliable routing in such an environment is very difficult task. In particular, it is essential for wireless routing protocols to provide some sort of QoS guarantees by incorporating metrics like achievable throughput, delay, jitter, packet delivery ratio, etc. In this paper, we compare and analyze the performance of various wireless routing protocols over MANETs. The source nodes are modeled using video trace files generated from real time video streams using H.264/SVC codec. Our basic goal of this paper is to analyze and exploit the in-built support for real time multimedia applications over MANETs. Performance evaluation and analysis of various wireless routing protocols over huge number of different scenarios is conducted. The results that evaluate the network performance are obtained using simulation in terms of packet delivery ratio, routing overhead and average end-to-end delay. The routing protocols are analyzed against the effects of change in network scalability (both in terms of size and number of nodes) and network load. Results obtained from simulations shows that it is possible to transmit multimedia applications traffic with limited support for video quality over MANETs.
