基于信号强度的分组帧时隙ALOHA防碰撞算法
Grouping Framed Slotted ALOHA Anti-collision Algorithm Based on Signal Strength
摘要
Abstract
To solve the low throughput of current ALOHA anti-collision algorithms, the Signal Strength Grouping Framed Slotted ALOHA( SSGFSA) algorithm is proposed,which exploits the energy transmission characteristics between Radio Frequency Indentification( RFID) reader and tags,improves the Framed Slotted ALOHA( FSA) algorithm to group tags,and distributes tags into frame slot according to received energy strength for reducing the probability of collision. Simulation results show that the maximum throughput of the algorithm is up to 50%,better than the theory value of the FSA algorithm and Collision Grouping Algorithm( GCA) in the case of the ratio of the tag number and the frame time slot number is less than 1 . 8 .关键词
