In this paper, the authors present a new approach to energy efficient routing in wireless sensor network. Here multiple routing paths are created based on the energy status of the nodes and they are used one after the other resulting in utilizing the energy equally from all the nodes in the network. The periodic update messages are minimized by using back up node and having every node broadcast its energy status to its neighbors prior to its death i.e. when energy of a node goes below minimum threshold.
