Dynamic share energy provisioning service for one-hop multiple RFID tags identification system

Internet of Things applications using RFID sensors are a challenging task due to the limited capacity of batteries. Thus, energy efficient control has become more critical design with RFID sensor integrating complex tag identification processing techniques. Previous works on power efficient control in multiple RFID tags identification systems often design tag anti-collision protocols in identification process, and seldom consider the features of tags are able to detect energy within its radio rang among each other. This paper is dedicated to developing a share energy provisioning (SEP) strategy for energy-limited multiple RFID tag identification system. First, SEP can dynamically adapt the variable energy resources due to the cognitive radio technique. Second, SEP combines the energy control with tags groups in wait time T, through classifying the tag into different groups according to its distances. Third, it introduces the optimization theoretical analysis energy for multiple RFID tags identification system, so as to minimize the time and energy of it takes to send tags data to reader. Finally, it shares the energy resource as different energy harvest under energy-limited RFID systems. Experimental results demonstrate the energy efficiency of the proposed approach.
