Performance of Energy Efficient Relay and Minimum Distance Clustering for Wireless Sensor Networks

In this paper, the performance of energy efficiency of cluster-based Wireless Sensor Networks (WSNs) is investigated. The authors consider the effect of Cluster Head (CH) and Relaying Nodes (RN) selection on the energy consumption in WSNs. With the Fixed Clustering Algorithms (FCA), they propose Energy Efficient Minimum Mean Distance (EEMMD) algorithm and Energy Efficient Relay and Minimum Distance (EERMD) algorithm to improve the energy efficiency for WSNs. Simulation results show that the EEMMD can slightly improve the energy efficiency. However, the proposed EERMD can largely improve both the energy efficiency and lifetime of WSNs.
