Prolonging the network lifetime is the most challenging task in the design of Wireless Sensor Networks (WSN). Using battery power effectively prevents sensor nodes from early death. Topology Control (TC) is one of the best attempts for saving battery power and to extend the network lifetime. TC is decisive in obtaining an energy efficient network without affecting the connectivity and other properties. Incorporation of a suitable clustering schema in a WSN, results in a reduced topology. Clustering refers to grouping of sensor nodes into non-overlapping regions and selecting the best node as cluster head for data forwarding. Though extensive research is carried out in this region, Cluster Head selection is based on energy.
