Abstract:
-Localization in wireless sensor networks is an open challenge. The work is based on the localization of mobile nodes in wireless sensor networks (WSN) by using the Received Signal Strength Indicator (RSSI) method. A trilateral localization algorithm based on RSSI has been proposed to localize the mobile sensor nodes. It is advantageous to apply RSSI based algorithm as it has solved the problems of cost, power utilization and reliability in wireless sensor networks. Furthermore, RSSI based algorithm has been compared with the existing techniques. Results shown in the paper are the evident of the situations where RSSI is considered best techniques of localization.
