Sensor networks are currently an active research area mainly due to the potential of their applications. In this paper, the use of wireless sensor networks for Intelligent Location Identification System(ILIS) is discussed. An innovative system to locate buses in and around the city is presented in this paper. Wireless transceivers are used by the system to detect the location of buses. All the data gathered are stored and analyzed with special non duplicate data acquisitions algorithm for elimination of duplicate data.
