Power Aware Routing in Wireless Mobile Ad Hoc Networks

Wireless mobile ad hoc networks are gaining importance because of their flexibility, mobility, and ability to work with a limited infrastructure. If the battery of a node is drained out, then it cannot communicate with other nodes and the number of dead nodes makes the network partition. In order to overcome the network partition problem, this chapter presents different routing algorithms for wireless mobile ad hoc networks. Different routing algorithms use different metrics, namely transmission power, residual battery capacity and noncritical nodes to forward data packets from the source to destination. Minimum total transmission power routing uses the transmission power as metric to forward the packets but it cannot increase the lifetimes of the node and network. In conditional max-min battery capacity routing, it increases network lifetime and reduces power consumption over the network. Noncritical nodes with more residual battery capacity based routing models will increase the network lifetime and network throughput.
