With the proliferation of portable computing devices and ascending popularity of group-oriented computing,multicast routing of mobile Ad Hoc networks remains a challenging research subject.Since nodes move around in such networks and members join and leave from the multicast group,it is difficult to manage the multicast group and to maintain routes.A multicast routing protocol based on clustering structure is proposed.Using the protocol,clustering structure is formed based on ID number and flag of node.Then multicast tree is built on-demand.In maintenance process,control packets are delivered to local clusters which are related to the multicast routing.Simulation experiments show that the protocol can maintain high packets delivery ratio and stable control messages overhead.It will provide an effective solution for multicast communication in large scale networks.
