In the field of wireless sensor network, localization is one of the main issues. Localization is a process of finding the location of nodes in a sensor network, which provides the basis for routing, tracking and other communication aspects of network. Hence localization is a significant criterion. In a 2D plane a node requires at least three anchor nodes location information for localization. One of the main methods to improve localization accuracy is to increase the count of anchor nodes. But this is restricted due to the hardware constraint, cost, and energy consumption and so on.
