Power aware reliable routing to support real time traffic in mobile ad-hoc network

A mobile Ad hoc network (MANET) is a collection of wireless nodes that forms a network without central administration. The nodes in such kind of network serve as routers as well as hosts. The nodes can forward packets on behalf of other nodes and run user applications. The energy consumption of the nodes is a critical factor in the operation of a mobile ad hoc network. The existence of a node with low energy may degrade the performance of the system as the node participate in the route discovery phase, but due to low energy it does not forward the packet or it does not participate in message forwarding phase. Such type of node selection will degrade the system performance, minimizes the packet delivery ratio, and maximizes delay thus increasing energy consumption. So an important objective is to consider Energy Aware design of network protocols for Ad hoc network environment. The proposed scheme is incorporated with the route discovery phase of AODV and by simulation using NS/2 it is observed that the proposed algorithm is better than AODV in terms of packet delivery ratio and network lifetime.
