Abstract: Multicast sessions arc expected to be an efficient communication scheme especially for multimedia applications in mobile Ad hoc networks. A new resource allocation algorithm was proposed for wireless Ad hoc networks with multi-rate multi-cast capability. It uses a price-based approach to solve the multi-rate multi-cast problem. And it can adaptively allocate network traffic such that the aggregate utility for all sessions is maximized. Simulation results show that the proposed algorithm not only has good convergence, but also its multi-rate multi-cast capability allows users with different channel to achieve maximum performance, thereby increasing the network throughput.
