Policy-Based Clustering Multicast Routing Algorithm of Ad Hoc Networks

As the increasing of mobile Ad Hoc network applications, and the demand of group-oriented computer and communication, multicast routing technology has become the focus of the study. As the increasing of ...the scalability of the multicsat routing protocol becomes an important issue. In this paper, based on MAODV, an improvement protocol with policy-based clustering multicast routing is put forward according to the clustering system structure of ad hoc networks. The multicast routing tree is constructed by self-repression flooding policy, and policy of priority is used to maintenance the multicast routing tree. The simulation shows that the improvement could reduce the routing overhead and delay.
