Research on the improvement of multicast Ad Hoc On-demand Distance Vector in MANETS

Tree-based multicast routing provides fast and most efficient way of routing establishment for the communications of mobile nodes in wireless Ad Hoc networks. MAODV (Multicast Ad Hoc On-demand Distance Vector) is one commonly known tree-based multicast routing protocol, which has minimal control overhead and route acquisition latency. This paper presents a way to improve the throughput of the system and reduce the number of mobile nodes participating in multicast routing algorithms, which will significantly reduce the routing-related control overhead. A systematic performance evaluation is done by performing certain simulations under NS-2. The applicability of these protocols to diverse situation are also studied and discussed.
