Abstract

Wireless sensor network includes hundreds or even thousands of sensor nodes, which are devices with low energy and often impossible to be replaced or recharged. For this reason, efficient use of energy is one of the major challenges in these networks. One way for increasing energy efficiency in such networks is clustering. Clustering protocols such as LEACH, TEEN, SEP and DEEC randomly select the cluster heads for the clustering process. This causes the cluster heads to be close together, decreasing the efficiency of protocols. For this reason, we proposed a new approach called EBDCH. In this method, when cluster heads are close together, we distribute them based on the energy situation. The proposed approach runs on the clustering protocols. The simulation results show that with the implementation of the proposed method, throughput is increased and network lifetime is improved compared to protocols LEACH, DEEC, SEP and EEHC respectively at 26%,28%,37% and 36%.
