摘要
目前舰船通信网络中的RFID标签防碰撞方法,对网络中时隙规划能力弱,导致舰船通信网络中的RFID标签防碰撞过程存在通信开销大问题,因此针对这个问题,重新研究基于二时隙算法的舰船通信网络中RFID标签防碰撞方法。构建舰船通信网络中RFID标签碰撞模型,确定RFID标签帧值;充分利用二时隙算法对网络中,时隙的规划能力,使网络负载与帧值相一致,防止RFID标签碰撞。实验结果表明,与其他方法相比,此次研究的舰船通信网络中RFID标签防碰撞方法,对时隙利用率更高,产生的通信开销更低。
At present, the anti-collision methods of RFID tags in ship communication network have weak ability of time slot planning in the network, which leads to the problem of high communication cost in the process of anti-collision of RFID tags in ship communication network. Therefore, in view of this problem, this paper re studies the anti-collision method of RFID tags in ship communication network based on two time slot algorithm. The collision model of RFID tag in ship communication network is constructed to determine the frame value of RFID tag;the ability of two time slot algorithm to plan the time slot in the network is fully utilized to make the network load consistent with the frame value to prevent RFID tag collision. Experimental results show that compared with other methods, the anti-collision method of RFID tag in ship communication network has higher utilization rate of time slot and lower communication cost.
