A Power-Aware Dual-Tree-Based Multicast Routing Protocol for Mobile Ad Hoc Networks

[[abstract]]A mobile ad hoc network (MANET) is an interconnected system of mobile hosts without a fixed infrastructure. In MANETs, each mobile host has multi-hop transmission capability, and it has to serve as a router. Because of the dynamic topology and limited resources of mobile hosts, the routing scheme in MANETs presents an important challenge. To improve battery power efficiency in MANETs, many routing algorithms have been proposed. Similarly, a stable routing path is equally important for MANETs. In this paper, a power-aware dual-tree-based multicast routing protocol (PDTMRP) for MANETs is proposed. Battery power was used in the route discovery to eliminate unstable paths. To achieve the load balance two multicast trees were constructed. Finally, simulations were conducted to show that the proposed routing scheme outperforms the MAODV routing scheme
