The reader collision problem (RCP) is the key problem affecting the reading efficiency in RFID systems. A novel anti-collision protocol-DREAM protocol is proposed to solve the reader collision problem in RFID systems. The new protocol dynamically selects temporal control centers to perform as cluster headers based on interference conditions and arranges the communication sequence of readers reasonably to completely avoid signal collisions among multiple readers. Both analytical and simulation results show that comparing to the current advanced PULSE protocol, DREAM protocol increases the reading efficiency significantly and meanwhile reduces the power consumption.
