Abstract

Ad-hoc network are flexible, self-configurable, easy and fast to deploy. There is a growing need to supports better than best-effort quality of services (QoS) in mobile ad-hoc networks. A lot of research has been done mainly in the area of routing and isolated Ad-hoc network. The QoS is very challenging and important in the multimedia and real time application environments. Therefore a QoS architecture for Ad-hoc network is necessary that can internetwork with infracture based QoS approach. In this research paper the performance analysis of the scheduling scheme that is mostly used in the MANET’s network is done. The comparison is based on the end-to-end delay, maximum throughputs and jitter (delay variance). It is found that DiffServ is the best scheduling technique as compare to WRR,WF and Strict priority technique.

Abstract

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any existing infrastructure. Two mobility models Random Waypoint and Group mobility are commonly used in MANET scenario. In this paper, the effects of various mobility models on the performance of three routing protocols Bellman Ford, Adhoc On Demand Distance Vector(AODV) and Zone Routing Protocol(ZRP) have been studied. For experiment purposes, two mobility scenarios: Random Waypoint, Group Mobility have been considered. These two Mobility Models are selected to represent possibility of practical application in future. Performance comparison has also been conducted across varying node mobility. Experiment results illustrate that performance of the routing protocol varies across different mobility models and mobility. Results show that the protocol performance may vary drastically across mobility models and performance rankings of protocols may vary with the mobility models used.
