Zigbee technology is here to stay. With current market trends it is to be understood that it will play a vital and major role in low rate wireless personal area networks.Zigbee networks facilitate numerous applications such as consumer electronics, home area networks, health care monitoring and environmental monitoring. Effective routing in wireless sensor networks is critical to conserve energy resources for the longevity of the network. In this paper we propose energy efficient cluster tree architecture for home area network. The reconfigurable architecture improves the Zigbee network performance by distributing equivalent load among its data fusing heads on basis of leftover energy. Simulations show that using such self organizing cluster tree topology is most effective in terms of energy consumption as compared to simple Zigbee mesh networks.
