Traffic-Energy Balanced Routing Protocol with Two-direction Routing

Ad hoc network is usually built up by battery-powered nodes, so the energy is limited, and the networkpsilas lifetime often depends on several hot nodes. This paper puts forward a routing protocol AODV-TEB (ad hoc on-demand distance vector - traffic-energy balanced) to solve this problem. In AODV-TEB, each node calculated its traffic load per second, and got its left battery, then formed a nonlinear weight of the node. When the battery was high, the weight mainly depended on the traffic load. When the battery was low, the weight mainly depended on the battery. Unlike a single-direction routing protocol, each node in AODV-TEB selected its up-link node and its down-link node according to their weights, the smaller, the better. The weight of a route was the maximum weight of the nodes on the link. AODV-TEB got all available routes to the destination, and selected one with the smallest weight. According to the simulations, AODV-TEB averaged the lifetime of the nodes, therefore prolonged the lifetime of the network. And when the battery was enough, AODV-TEB avoided competing with other users for hot nodes, hence reduced the probability of collision, and improved the packet delivery ratio.
