Optimized Multicast Routing for Improved Survivability of Mobile Ad Hoc Networks

A Wireless Ad hoc Network consists of mobile nodes with energy constrained batteries. In this paper, we have proposed an Optimized Lifetime Multicast Tree (OLMT) algorithm that constructs a minimum energy multicast tree resulting in minimum total transmission power consumption,thereby increasing the lifetime of the network. We observe that, simulations carried on NS2 provides significant improvement in the number of multicast requests realised when compared with earlier works.
