Localization is one of the most fundamental problems in wireless sensor networks, since the locations of the sensor nodes are critical to both network operations and most application level tasks. To solve the localization problem for find out the location of sensor nodes in wireless sensor network, a Anchor based localization scheme for wireless sensor networks with energy efficiency is presented in this paper. The authors develop a standardized clustering-based approach for the local coordinate system formation wherein a multiplication factor is introduced to regulate the number of cluster head nodes and neighbor nodes and the degree of connectivity among cluster head nodes.
