Abstract—Based on the ODMRP (On-Demand Multicast Routing Protocol) in MANET (Mobile Ad hoc NETwork), a reliable ODMRP (R-ODMRP) is proposed for preferable throughput and especially suited for high-speed MANET, which includes packet acknowledgement, lost packet recovery, secure authentication and QoS based packet delivery. With the exploration of active network, R-ODMRP constructs the multicast routing based on the cluster, establishes a distributed mechanism of the acknowledgment and recovery of packet delivery. Along with cluster key distributed in one cluster, this protocol can authenticate the consistency of multicast source and receivers depending on local security strategy. The specific mesh links are adaptively chosen by virtue of the descriptive QoS vectors meanwhile, the forwarding nodes can flexibly schedule different multicast packets according to the types of the multicast applications. The performance of the proposed schemes is evaluated based on the network simulator and achieves a significant improvement.
