An ad hoc network is a dynamically reconfigurable wireless network with no fixed wired infrastructure. The primary concerns in ad hoc networks are bandwidth limitation and unpredictable dynamic topology. The On-Demand Multicast Routing Protocol (ODMRP) was designed for multicast routing in ad hoc networks. In this paper, we propose a cluster-based on demand multicast routing protocol(SC-ODMRP) to the lack of extension of flat multicast routing protocols in large scale ad hoc networks. Simulation results show that using clustering base ODMRP improves network performance in terms of end-to-end delay and control packets. Also we propose a link stability approach to design a stable multicast algorithm. By this approach data delivery will be increase, and overhead will be decrease.
