Architecture Development for Efficient Sensor Tag Management

The possible integration of sensing information with RFID data can be accomplished by using sensor tag instead of using RFID tag only. Although EPCglobal provides standard architecture framework for processing RFID information, the diverse RFID applications and services necessitate collection and manipulation of integrated RFID-sensing information at the same system. Systems deploying sensor tag can achieve both ID data and sensing data simultaneously. However, it is a big system challenge to monitor sensing data and manage sensor tags using existing standards. Moreover, efficient control and management of sensor tag moods and states is also an issue in saving tag battery power and storing necessary sensing information in sensor tag memory. To fulfill all application requirements and manipulation of RFID-sensing data require efficient management of sensor tag. In this paper, we propose a new system architecture for efficient sensor tag management based on EPCglobal framework.
