Routing Algorithm For Power Awareness In MANET

In Mobile Ad hoc networks (MANETs), portable mobile nodes communicate directly with each other without any central infrastructure. In the absence of central infrastructure, a node establishes communication network and act as router as well. Nodes are battery operated and mobile hence network topology changes frequently. In MANET, resources are limited. Battery power of the node is one of the important resources. Ad hoc On demand Distance Vector AODV is a reactive protocol which establishes the network connection when needed. When any node has some data for communication, AODV protocol will establish the route. In AODV, route breaks when nodes run out of battery power. Purpose of this work is to maximize the network lifetime by avoiding the routing through nodes with less battery power. Routing will be through the nodes with sufficient battery power. Power aware routing algorithm is developed and simulated using NS-2. Further more we have compared the results with conventional AODV and demonstrated that remaining battery energy of the nodes increases.
