%X This paper presented a kind of relative mobility of nodes based adaptive demand-driven multicast routing pro- tocol RMNAM. RMNAM protocol inherits the on-demand features of ADMR protocol, and introduces the concept of relative mobility of nodes. On the one hand, the protocol uses the relative mobility of nodes as an important factor in multicast forwarding tree, which improves the robustness of the multicast paths; on the other hand, the protocol optimi- zes the transmission switching strategy of source node by consulting the global repair frequency and the average relative mobility of nodes to promote adaptability. The simulation results show that RMNAM protocols improve ADMR proto- col in the packet delivery ratio and transmission delay, and it keeps the advantages of effectiveness and scalability com- pared with ODMRP.
