A Study on Wireless Sensor Networks Localization

Poonkodi.K, Vinodhini.B, Karthik.S

Localization is one of the main issues in wireless sensor networks (WSNs), since the location of the sensor nodes are critical in network operation. Although there is lot of range based and range-free localization approaches were created to find the accurate location information of sensor nodes in wireless sensor networks, but not even a single approach to find the exact location information of the sensor nodes. In this paper, we present a comprehensive survey on sensor localization in WSNs covering both range-based and range-free approaches motivation, problem and performance.
