Energy Saving Routing Algorithm Based on Stable Zone in Mobile Ad Hoc Networks

In mobile ad hoc networks, the nodes are powered by batteries. So one of the most important merits when evaluating a given protocol is its ability to decrease node energy consumption and prolong network lifetime. Concerning this problem, an improved routing algorithm based on extreme prediction is presented for a mobile ad hoc network. It is an energy-saving and stable routing algorithm in which the stable zone is divided by the distance between two nodes and the link availability is calculated according to the area where the node is. The availability of a route is the minimum link availability which consist the whole route and the most stable path is chosen to send information data. And the node adjusts its transmitting power referring to the location of the next hop. Simulation results show that the proposed algorithm decreases network energy consumption effectively compared with basic DSR (Dynamic Source Routing) protocol, and by extension, prolongs the lifetime of the whole network.
