MULTICASTING APPROACH FOR MOBILE AD-HOC NETWORKS AND ITS PERFORMANCE ANALYSIS

Abstract

A mobile Ad-Hoc Network (MANET) is a self-starting network formed on the fly by a group of mobile nodes without the aid of any centralized administration or established infrastructure. Since node in MANET is free to move arbitrarily, the network topology may change rapidly and unpredictably. So, designing an efficient routing protocol becomes a challenging issue for such a network and extensive research is going in this area. Several routing protocols have been proposed for MANET, which can be classified as proactive, reactive, and hybrid routing protocols. All of these protocols use the mechanism of blind flooding for the broadcasting of route request and route reply messages. Blind flooding results in severe broadcast redundancy leading to contention for channel access and collision in the network. Several mechanisms namely probabilistic scheme, distance based routing, location aided routing and cluster based routing have been suggested to dealing with blind flooding. Though all the...
