Abstract

In WSNs localization is an important issue for many applications as it increases the lifetime of the nodes, power consumption calculations, data routing etc., we optimized the localization of Wireless Sensor Nodes at a given network area where we used some known location Anchor nodes for better results. By considering the anchor nodes as reference nodes at given area, the localization of unknown sensor Nodes Location be able to be estimated, to approximate the sensor nodes triangulation method was adopted. In this paper Delaunay Triangulation (DT) method was implemented for exact estimation of unknown nodes in the network area. DT method proves better localization algorithm compared with other methods.  Anchor nodes measures the RSSI of nearest neighbour nodes, based on RSSI values DT method approximates the nearest neighbour nodes and DT triangles are formed.
