A cluster-head selection algorithm for Wireless Sensor Networks

The use of Wireless Sensor Networks (WSN) is anticipated to bring lot of changes in data gathering, processing and dissemination for different environments and applications. Energy consumption is the most crucial design issue in WSN. In order to solve the issue and prolong the network lifetime, energy resources of each node in WSN need to be effectively managed. With respect to energy efficiency, the best known protocols are hierarchical in nature. Energy consumption can be reduced efficiently by using clustering based hierarchical routing protocols. In this paper, an energy-efficient clustering approach called Improved Minimum Separation Distance(IMSD) is proposed. IMSD extends the existing MSD clustering algorithm. The simulation results show that IMSD is more energy-efficient, implying that it is more effective in prolonging the network life time.
