改进动态帧时隙ALOHA算法
an Improved Dynamic Frame Slotted ALOHA Algorithm
摘要
Abstract
One of the popular anti-collision algorithms, ALOHA-type algorithm shows good performance when the number of tags to read is small. However, as the number of tag increases, they generally require exponentially increasing number of slots to be identified. In the paper, we propose a new anti-collision algorithm called Improved Dynamic Framed Slotted ALOHA （IDFSA）. It estimates the number of unread tags before adjusting the size of the frame to obtain the optimal system efficiency. Simulation results show that the proposed algorithm reduces half of the system time delay by the conventional algorithms when the number of tags is 500.关键词
