Abstract: In recent years, Wireless sensor Network (WSN) node localization techniques play a significant role in several domains in censorious condition for instance tracking and monitoring of events. Distance vector hop algorithm is found to be the best among other localization algorithms due to its simplicity, low cost and less complexity. Whereas the localization accuracy is reduced at the point of least anchor node count. For the purpose of improvisation of localization accuracy, an Enhanced Received Signal Strength Indicator (ERSSI) based Advanced DV-hop (ADV) algorithm is proposed. The origin node and terminal node distance is calculated depending upon the hop length and hop to the beacon nodes using ADV algorithm. Better estimation result is achieved by using least square method. The received signal strength is estimated using projected ERSSI algorithm to enhance the stability and low power consumption. This proposed approach improves localization accuracy when compared with existing techniques. Moreover, localization accuracy is estimated based on localization error and localization error variance.
