Optimal Cluster Head Election Algorithm for Mobile Wireless Sensor Networks

Abstract

Mobile Wireless Sensor Networks (MWSN) comprise of small sized sensors with limited energy. Due to mobility their energy drains even faster than static WSNs. Clustering is a technique used for conserving of energy in MWSNs. This work presents an improved cluster head election mechanism which minimizes number of time CH election takes place in a MWSN. Further with this technique chances of cluster left unattended by cluster head also gets reduced, thereby improving data flow in MWSNs.
