摘要
在RFID系统中,由于多标签引起的冲突一直是影响系统性能的主要问题。ALOHA算法是解决标签碰撞问题最有效的方法之一。当系统中标签数过多时,帧时隙ALOHA算法和动态帧时隙ALOHA算法,都会降低系统效率。因此我们提出一种利用二进制树形分组的时隙ALHOA算法。由于只需要对标签进行简单分组就可以有效的提高ALOHA算法的效率,所以此方法更具有实际意义。
In RFID system, one of the important problems is the collision among tags, which lowers the efficiency of the system. ALOHA algorithm is one of the most effective methods to solve the collision problem. Both Frame Slot ALOHA algorithm and Dynamic Framed Slotted Aloha algorithm will reduce the system efficiency when there are thousands of tags. Working on the improvement of the grouping methods, we propose an algorithm named split-ALOHA with a novel grouping method that split tags as a binary tree. As only simple division of tags can effectively enhance the efficiency of ALOHA algorithm, so this method has more practical significance.
