Pervasive Architecture for Object Tracking using RFID tags

A completely visible Pervasive Transaction Environment where it is possible to link all related distributions of physical objects and trace their mobility through their entire life process, has been elusive. We propose an architecture for pervasive real-time tracking of object distribution and subsequently present an efficient mechanism for performing Recall of RFID tagged objects that were previously distributed but turned out defective. We mathematically model the distribution and recall process and get a stochastic estimate of the average spread of object distributions and the number of recall messages required. Currently we are extending on our architecture and trying to develop a prototype of the architecture and the application layer protocol to manage the mobility of the tagged objects in a multi-organization scenario.
