Energy aware Routing in Location based ad-hoc networks

In wireless ad-hoc networks, there are several characteristics different with wired networks. The differences are changing of network topology, limited resources like bandwidth and energy and so on. In these days as the energy issue becomes more important, it is required to research about the efficient resource allocation methods optimized in wireless networks. In the paper, we improve LAR (Location-Aided Routing) which is one of the most famous location based routing methods. This kind of technique uses information about the location of mobile node through GPS technique. Our new protocol considers both areas of routing and energy. At first, propose a more efficient routing method which minimizes the spread of unnecessary control messages. Secondly, an energy aware method is proposed to select proper transmission power by the distance between nodes. And finally, we make a new function to select next hop which considers both of distance and energy. The result of simulation shows that performance of lifetime is improved about 12% compared with LAR.
