Abstract

Wireless Sensor Networks (WSNs) have become one of the most motivating research areas. In this paper we have proposed an Optimized Distributed Energy Efficient Clustering scheme for Heterogeneous WSNs (ODEEC) to prolong the network lifetime and stability period. This protocol proposes an optimization of the Cluster Head (CH) selection by modifying the probability function of heterogeneity. The network field is classified into two parts inner region and outer region. The sensor nodes decide to become cluster head nodes or not based on their positions from Base Station (BS) as well as the probabilities of heterogeneity model. Simulation results show that ODEEC achieves better performance among the relevant protocols in terms of throughput as well as network lifetime and stability period.
