Efficient Multicast Routing in MANET

Abstract

Mobile ad hoc network (MANET) is dynamic, self-configuring, distributive, infrastructure-less and self-organized wireless network having collection of independent mobile nodes which are free to move arbitrarily. MANET uses a multicast communication in various applications in which close collaboration of teams is very crucial. In this paper, we propose optimized expanding ring search (OERS) protocol which uses modified expanding ring search method during route discovery process and also analyse the performance of proposed protocol and multicast ad hoc on demand distance vector (MAODV) routing protocol for varying node speed parameter value. For experiment purpose, we have also considered different numbers of receiver nodes in multicast group. Using different performance metrics like, normalized routing load, throughput, end-to-end delay and packet delivery ratio, performance comparison has also been conducted for varying node speed and varying number of receiver nodes. It has been observed that performance of OERS and MAODV protocols is affected by the node speed value and number of receiver mobile nodes in the multicast group. Considering all scenario results, OERS outperforms the MAODV.
