Abstract: An energy-efficient routing is implemented in this paper for wireless sensor networks. Most of the existing routing schemes assign energy-related costs to network links. The main objective in this paper is to reduce the energy consumed by the network links and to obtain the shortest paths for the nodes to balance the flowing traffic within the network and increase its lifetime. Most of the existing schemes are not known the optimal link cost values and the maximum achievable lifetime, So framework is provided in this work to analytically derive the best achievable performance that can be obtained by Lifetime efficient routing algorithm based on the shortest-path approach. Given a network configuration and an energy consumption model, the framework provides the optimal link cost assignment which yields the maximum lifetime in a distributed shortest-path routing strategy.
