Efficient and cost effective tracker in monitored area network [t-man] using RFID

Abstract

In this paper we analyze how radio frequency identification (RFID) technology can be used to efficiently and cost effectively achieve and improve the tracing and tracking in a monitored area network. In particular we describe implementational issues associated to tracing or tracking of any mobile platform (person, robot etc) equipped with a RFID transmitter. We present a `t-monitored area network' model which is more flexible and dynamic and can achieve appropriate location sensing, on the basis of which it would be able to trace the path of a mobile agent in real-time. Our solution works on a standard local area network using a specially designed hardware. Our analysis and practical results are based on actual hardware implementation and promises a very fine granularity in time for consistent location update requests. Our design do not intend to find the exact location coordinates of a RFID tag, which is although acceptable in most of the applications unlike defense where accuracy is crucial, for which our system is modular and flexible enough to allow later modifications as per the specific requirement with some addition or subtraction in the overall cost. Our analysis and practical results indicate that the hardware system designed is low-cost and efficient
