Abstract

Multicast routing is an efficient method to lead data packets from one source group to several nodes as destination group. Although multicast routing algorithms could be efficient in many situations but their routing mechanism like as route request flooding packets likely results in poor performance in comparison to unicast routing algorithms. In this research, two efficient methods are proposed to improve the performance of On Demand Multicast Routing Protocol (ODMRP). The main proposed method tries to establish a small, efficient, and high‐quality forwarding group. This is achieved by augmenting the Join Query packets with additional information such as speed, power level of node, and link bandwidths. Besides, the control overhead is further reduced by restricting the domain of control packet flooding (by restricting the domain of control packet flooding). The performance evaluation shows that the proposed scheme increases the packet delivery rate by up to 40%, while reducing average end‐to‐end delay and consumed power by about 35% and 45%, respectively.

Summary

Introduction

A mobile ad hoc network (MANET) [1,2,3,4] is formed by wireless mobile nodes which dynamically set up themselves to initiate and maintain a wireless network without any predefined infrastructure. Mesh-based multicast routing algorithms establish a mesh to forward data packets to receiver group. They could be more efficient than tree-based algorithms due to redundant routes in mesh topology. For establishing the delivery structure, a standard approach is to use network sending of control packets in throughout of network Two new methods have been proposed to improve the performance of the multicast routing protocols in MANETs. The first method exploits fuzzy logic control to deal with imprecise and partial information during the construction phase of a forwarding structure.
