Radio Frequency Identification (RFID) system is a new communication technology to identify the objects using electromagnetic waves. The main superiority of RFID systems in comparison with other identification systems, such as barcodes, is its ability in simultaneous identification process, but when more than one tag wants to communicate with the reader, collision problem occurs and wastes time and increases energy consumption. This reduces efficiency of the identification process in RFID systems. Collision problem happens when the reader has to identify more than one tag at the same time. Consequently, it is essential to develop an efficient anti-collision algorithm to save …
