Low Power Localization with Location Verification for Wireless Sensor Networks

The purpose of localization in Wireless Sensor Network is to establish the position of the nodes at a particular point of time as the nodes are mobile. Locating information is not only used to realize it s position but it can also be used to increase outing capabilities and load balancing of network. This paper proposes the combination of clock algorithm and rectangle truncation (RT) localization algorithm for locating objects even in a fading-signal sensor environment. The paper further presents a location verification mechanism to increase the accuracy and consistency of the estimated object location. It can be classified as low power algorithm as it does not need any special hardware and the computations are minimized.
