Abstract:
This paper proposes and evaluates a new clustering algorithm: Weighted Election Probabilities Clustering Scheme (WEPCS) for Heterogeneous Wireless Sensor Networks (HWSNs). WEPCS is an improvement of the Energy Efficient Heterogeneous Clustered (EEHC) protocol. The modification proposed allows the election of Cluster Heads (CHs) using different weighted probabilities. The WEPCS algorithm aims mainly to improve network stability period and the network throughput. An Experimental evaluation is presented and the results show that the WEPCS achieves longer life time and more throughput than the existing clustering protocols in heterogeneous environments.
