A composed energy aware metric for WSNs

In the current power aware- Directional Source Aware Routing Protocol (DSAP), the node with the most power and with the shortest path will be chosen for the next hop. The problem with this protocol is that, the same nodes might be chosen over and over again and will result in the depleting of energy in the nodes and will also cause unbalanced power dissipation in the network. In this paper, a new metric to solve this problem is proposed. In order to test the proposed metric, a simulation model was developed. This paper will start with the introduction of wireless sensor network and the DSAP. This is then followed by the explanation on the new metric and also results obtained from the simulation. Finally, the conclusion will be presented.
