(Abstract )An improved reliable multicast routing protocol is presented based on On-demand Multicast Routing Protocol(ODMRP). The protocol using NACK aggregation is to contain number of control group as precondition. The loss events of data packet in amount are centralized in an aggregated NACK. The aggregated NACK is added into Join Table group to realize the retransmission by father node to get reliable ODMRP communication. Simulation result shows that the packet delivery ratio of the improved protocol enhances mostly up to 2.5%.
