Applications of ad hoc networks are increasing in recent years because of their ease of deployment. Mobile ad hoc networks multimedia applications require an efficient and effective quality of service-aware multicast routing scheme. Supporting quality of service in an ad hoc environment is a major challenge due to unpredictable and rapidly changing topology. In this article a novel cluster-based QoS aware multicast routing protocol (CQMRP) for mobile ad hoc network is presented. In this scheme the multicast routes are constructed in a distributed manner. Analysis shows that the control overhead generated by the proposed QoS aware multicast routing scheme is less than the other related schemes. The simulation result shows that the packet delivery ratio of the proposed scheme is better than HQMRP in higher mobility scenario. In addition to that it is highly adaptable to topology changes.
