RFID is a technology that used to identify the objects automatically. But identifying multiple objects simultaneously caused for collision which reduces the efficiency of the system. Because of the collision, some tags cannot be identified. This is a major disadvantage of the RFID system. The collision will lead to loss of data and tag identification. There are various anti-collision algorithms used to avoid the collision in multi-tag environment. Every anti-collision algorithm is efficient than earlier algorithms including time complexity. But the problem exists. The anti-collision algorithms are basically classified into two categories. They are ALOHA based algorithms and tree based algorithms. The new anti-collision algorithm that introduced in this paper is based on the ALOHA protocol which can improve the time complexity. And different anti-collision algorithms are analyzed.
