Energy conservation is a critical issue in wireless sensor networks for node and network life, as the nodes are powered by batteries. One way of doing so is to use only local information available to the nodes in the network. This article evaluates a number of power-aware routing protocols based on local information only. The simulation shows that basing the routing decision on the remaining power of neighbouring nodes is not by itself enough. Instead, using the directional value and the sum of power remaining at the next neighbours gives the routing protocol a broader perspective about the condition of the network from a local point of view and enhances the decision process.
