A proposed Energy Efficient Distance Based Cluster Head (DBCH) Algorithm: An Improvement over LEACH

Wireless Sensor Networks are known for their wide range of applications in which no human intervention is required. But the main challenge of Wireless Sensor Networks lies in achieving communications with low energy consumption. In order to overcome the problem of energy consumption, a well-known clustering algorithm, LEACH (Low Energy Adaptive Clustering Hierarchy) was designed. However, LEACH has some disadvantages. In this paper, we propose a new clustering algorithm based on LEACH. It establishes a new Threshold which includes the node energy and distance between node and base station and distance between cluster head and base station for measuring the threshold value. Simulation results show that proposed algorithm is better than LEACH in balancing the node energy and thus enhancing the network lifetime.
