Determining Region of Confidence for the Purpose of Localization in Wireless Sensor Network

Abstract

Localization of a sensor node and target tracking have become an extremely important issue for many applications over WSN. To detect a sensor node is easy if there is no error found between the sensor and reference node. But in real life there is a high possibility that error exists. There are various techniques to determine the position of sensor node but here we are not concern about the techniques. Here we mainly emphasize on calculation of the error percentage between experimental and theoretical distance. The BTS works here as reference node. Here, we have worked with three BTSs in 2D environment. When the BTS wants to measure the distance of the targeted sensor node it increases its range of circumference. After increasing the range of the three BTS they intersect and create a common overlapping area. Our work is to estimate this area.
