چکیده
In this paper, bin-slotted hybrid search algorithm (BHS) combined slotted ALOHA procedure with bin-tree procedure is proposed and analyzed. Also, the performance of proposed anti-collision algorithm is evaluated as comparing the BHS algorithm with a standard bin-slotted algorithm (BSA) through the simulation. The performance of the proposed BHS algorithm is improved by dynamically identifying the collided-bit position and the collided bins stored in the stack of the reader. As the results, the reduction ratio of the number of request command that the reader sends to tags in its interrogation zone and the total recognition is about 59% for 1000 tags as compared with those of BSA algorithm. Therefore, the tag identification performance is fairly improved by using the proposed BHS algorithm in resolving a collision problem.
