A path based reliable middleware framework for RFID devices

The rapid interest in large scale RFID deployment has introduced interesting opportunities and challenges which includes handling of massive amount of RFID generated data, taking care of the error prone nature of the data and being able to provide a scalable solution for the applications. There has been research work that focuses mainly on item tracking applications but not item location applications. We propose a general infrastructure that is able to serve the item tracking applications as well as item location applications using the path based spatial and temporal stamping of RFID generated data. The system takes advantage of the data flow information at the system level to improve system performance.
