This paper presents a method of Weighted Back Tracing Algorithm for localization of the Gas leakage source based on weighted back tracing algorithm (WBTA) adopted using star topology Wireless Sensor Network. The relative signal strength of gas concentration tested by modeling means of exhaust gas, from a diesel operated vehicle, exposed to TGS 2201 gas sensors. The sensor data was transmitted to the PC monitor in order to detect gas concentration in PPM calibration. The results were collected to calculate error in gas leakage source location experimentally for various positions. The error has been estimated by actual position of the gas leakage source and calculated and negligible.
