Zone Based Multi-Path Disjoint Routing In Manet Using Zbmdr Protocol

Abstract

A MANET (Mobile Ad hoc Network) is an accumulation of wireless mobile nodes which are autonomous and can dynamically self-organize that creates aprovisional network topology. Numerouspossible applications of MANETs necessitate group communications among several nodes, which is supported by multicasting. In a dynamic environment, it is difficult to maintain group membership management, which is a challenging task to implement robust and scalable multicast routing. For that reason, a novel Zone Based Multipath Disjoint Routing (ZBMDR) is proposed. The proposed ZBMDR is disjoint at the zones which can establish multiple zone disjoint routes between the source and the destination network zones which help to develop the network lifetime and also to reduce the congestion and communication overhead. The proposed ZBMDR protocol is simulated using the NS-2 (NS-2.39) and the experimental results are presented.
