There are many different energy aware routing protocols proposed in the literature, most of them focus only on energy efficiency by finding the optimal path to minimize energy consumption. These protocols should not only aim for energy efficiency but also for energy balance consumption. In this work, energy balanced data gathering routing algorithm is developed using the concepts of potential in classical physics (16). Our scheme called energy balanced routing protocol, forwards data packets toward the sink through dense energy areas so as to protect the nodes with relatively low residual energy. This is to construct three independent virtual potential fields in terms of depth, energy density and residual energy. The depth field is used to establish a basic routing paradigm which helps in moving the packets towards the sink. The energy density field ensures that packets are always forwarded along the high energy areas. Finally, the residual energy field aims to protect the low energy nodes.
