Executive Summary

Target tracking is an important application type for Wireless Sensor Networks (WSN). Recently, various approaches [1- 11] are proposed to maintain the accurate tracking of the targets as well as low energy consumption. Clustering is a fundamental technique to manage the scarce network resources [12-19]. The message complexity of an application can be significantly decreased when it is redesigned on top of a clustered network. Clustering has provided an efficient infrastructure in many existing studies [1-8]. The clusters can be constructed before the target enters the region which is called the static method [1-4] or clusters are created by using Received Signal Strength (RSS) from target which is called the dynamic method [5-8].
