A balanced energy adaptive routing protocol with sector based node selection in underwater WSNs

In this paper we propose an energy balanced routing algorithm. Our scheme called Balanced Energy Adaptive Routing protocol, forwards data packets towards the sink through dense energy area to protect the nodes with relatively low residual energy. The key point in our proposed protocol is the presence of three conceited virtual fields. The first field, called virtual sector, is responsible for establishing the routing pattern which ensures the movement of the data packet towards the sink. Sensor node's energy is the second field which ensures that packets are always forwarded along the higher energy nodes. The third field is the residual energy field, it intends to protect the low energy nodes. Eventually the final verdict is taken with all three virtual potential fields.
