Wireless Sensor Networks play a vital role in applications like disaster management and human relief, habitat monitoring, studying the weather and ecosystems, etc. Since, the location of deployment of these WSNs is usually remote, the source of energy is restricted to battery. A Significant amount of work has been done by researchers in the past to achieve energy efficiency in WSNs. In this paper, the authors propose a scheme to optimize the power utilization in a WSN. Many of the WSN applications form a tree topology for communication.
