Location estimation is important for many applications in wireless networks. Now-a-days it is being used for military applications and location tracking. RSSI is a measure of signal strength to estimate the distance and to detect intruder by using fingerprinting technique by setting RSSI threshold value. There exists several approaches for analysis of Wi-Fi network which has demerits in terms of accuracy. Signal strength measurement technique includes range based, range free, and fingerprinting approach. Range based method is based on different physical characteristics including RSSI, Time Of Arrival (TOA),Time Difference Of Arrival (TDOA), Angle Of Arrival (AOA).RSSI is used in the proposed work which is obtained from the location database.
