Abstract :
Abstract:To provide a method for positioning ( source ) Using an array of sensors This study was conducted in 1394 . For this purpose, the positioning location Wireless communications networks were used. Receiver signal strength Indicator (RSSI) and time Difference of Arrival (TDOA) are main techniques that have been used in sensor node localization. Four anchor nodes were placed on corners of a square and the blind folded nod with the sounder at TDOA and RSS measurements was taken by averaging several consecutive readings. Then the blind folded node was localized using the LLS and CWLS estimator and methods of SI and SX. Combined algorithm The research will be presented The case that the source is close to the Sensors And when the source is away from the sensor Was a good answer . In general it can be concluded that positioning accuracy using combined method TDOA and RSS and intelligent Algorithms can be improved. Key word: Sensor array, positioning, Time difference of arrival, Received Signal Strength, Multipath, Line of Sight.
