Performance Evaluation of AODV protocol over E-TDMA MAC protocol for wireless ad Hoc networks

Abstract

In this paper, a new protocol for scheduling TDMA transmissions in a mobile ad hoc network has been considered. In this protocol, nodes may reserve time slots for unicast, multicast or broadcast transmissions. The protocol uses contention when generating the schedules, and its operation is distributed and concurrent, hence its operation is not affected by the network size but only by the node density. Consequently it is scalable and can be used in large networks. This protocol is termed E-TDMA (Evolutionary-TDMA). This last one is not based on the contention and there is a very little contention through another protocol for the MAC level that has been considered: Five Phase Reservation Protocol (FPRP). The protocol's performance has been studied via simulation of a routing protocol (AODV) over E-TDMA MAC and the change of MAC parameters in order to evaluate the impact of MAC protocol over routing protocol has been evaluated. © Springer-Verlag 2004.
