JWCN_V2_N2_RP2 Milad HajMirzaei Journal On Wireless Communication Networks 2320 - 2351 2 2 17 21 RFID, Collision, ID Distribution, Anti-Collision, Tag Collisions Milad Hajmirzaei proposes an efficient algorithm called IMAS (Improved Multi slotted scheme with Assigned Slots) algorithm which overcomes the problem caused by Tag collision. During the transmission of information from one reader, the collision occurs when more than one tag transmit its ID to reader simultaneously. When more than one tag with a same prefix respond in a slot, the collision will be detected by reader. More than 200 tags are used for experiment and the collision is less IMAS.
