Power Aware Metrics for Wireless Sensor Networks
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. In this
paper, we evaluate 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
neighboring nodes is not enough by itself. Instead, using
the directional value and the sum of power remaining at
the next neighbors gives the routing protocol a broader perspective
about the condition of the network from a local
point of view and enhances the decision process.
