Anticollision


Simultaneous transmissions in RFID systems lead to collisions. Communication between a single reader and a single tag can go without any collision. But when a single reader is communicating with morę than one tag or two or morę readers are operating in a closer network, probability of colliding of data arises. To solve this problem, we use some protocols like ALOHA, binary tree, query tree etc.
