This paper presents an RFID outdoor localization system that is able to localize hundreds of active transponders in the area of one square kilometer using three RFID receiving stations. The RFID outdoor locator is designed for the tracking of casualties during mass disasters. Active transponders are included in triage tags that are fastened to all casualties during the first wave of rescue operations...
Object localization is a key primitive in pervasive computing environments, where numerous applications depend on the rapid and accurate position estimation of objects. We present a general RFID-based localization framework that reliably determines the positions of objects with unprecedented accuracy and speed. This is achieved by varying the power levels of the RFID readers, calibrated against reference...
Out of several location sensing systems developed over the past few years, Radio Frequency Identification is one of the efficient techniques that uses radio waves for wireless communication. In this paper Radio Frequency Identification is used as a Colony based localized technique for accurate tracking of objects in Smart Homes. In order to accurately determine the position of an object, a backtracking...
