A Regenerating Code Based Data Restoration Scheme in Active RFID System

Due to the complex and uncontrollable operating environment of high dynamic active RFID systems, the risk of individual loss of RFID tags occurs from time to time, resulting in the loss of important data. On the other hand, the storage capacity of RFID tags is limited, such that the storage space of a single RFID tag cannot meet the storage needs. Therefore, how to achieve reliable cooperative storage of active RFID systems in complex and even hostile environments is extremely important. To solve the above problems, this paper studies the efficient cooperative storage of key data in active RFID system. Specifically, a data restoration scheme is designed by using regenerating code against individual loss for active RFID systems. Moreover, the optimization of scheme parameters is studied according to different application scenarios to ensure that key data can be successfully recovered under different RFID tag loss probabilities. Finally, the simulation platform is designed to verify the performance of our data restoration scheme.
