Fast and Simple Anti-collision Protocol based on Up-down Counter and one Bit Reader Response

Abstract

This paper describes a simple fast protocol of counter based anticollision approaches. The tag processing is depending on one depth counter and conflict pointer to determine its replying order and the current replying bit. The main advantage of the proposed protocol is the simple one bit reader response in the identification process. The one bit reader response will provide the tags all information about the new state of the current depth position of replying. The tags will transmit its IDs without reader interruption until the reader detects the collision state or the identification state. Based on this idea, the identification process will be faster than the traditional counter based anti collision protocols and the overhead information will be reduced. Performed computer simulations have shown that the collision recovery scheme is very fast and simple. The simulation results shows that the proposed technique outperforms most of the recent techniques in most cases.
