Energy Efficient Clustering Routing Algorithm in Wireless Sensor Networks

A wireless sensor node can only be equipped with a limited power source due to the several hardware constraints. Moreover, for most applications, replenishment of power resources is impossible. WSN lifetime, therefore, shows a strong dependence on battery lifetime. Thus the sources that consume energy during the operation of each node should be analyzed and maintained efficiently. In this paper, we propose a energy efficient clustering routing algorithm based on LEACH (EE_LEACH), which aims to balance energy consumption in WSN through modification of the threshold and multi-hop data transmission. Simulation results show that the algorithm can save node energy consumption effectively and prolong the network lifetime.
