Abstract

A mobile ad hoc network (MANET) is a distributed wireless network. The characteristics such as free mobility, self configuration, and fast deployment make MANETs suitable for various tasks. Multicasting can efficiently support a variety of applications and services. Most of existing multicast routing protocols in MANETs consider only one source in a multicast group and become inefficient when the protocol is extended to multi-source multicasting. In this paper, we propose a cluster-based multi-source multicast routing protocol to provide efficient multicasting in the multi-source multicast environment. The proposed shared forwarding cluster and cluster-based routing preserve forwarding efficiency as well as robustness. Simulation results show that the proposed protocol maintains the delivery ratio without losing efficiency in the multi-source multicast environment.
