摘要 合理部署光纤传感器物联网节点,可以提升物联网感知效果,解决物联网节点覆盖死角问题,延长其使用寿命,为此研究基于数据传输成功率的光纤传感器物联网节点部署方法。利用证据理论融合数据传输感知概率模型中光纤传感器物联网节点附近区域的综合感知概率;依据综合感知概率构建光纤传感器物联网节点区域覆盖模型,获取节点覆盖强度;利用萤火虫群算法移动覆盖强度即荧光素浓度较小的节点,计算其移动概率,判断其移动方向,最终完成部署;通过混合机制优化萤火虫群算法,提升部署性能。实验证明:所研究方法可有效部署光纤传感器物联网节点,且分布均匀;可以有效缩短节点移动距离,降低能耗;平均数据传输成功率与节点覆盖率高达99.6%与100%。 The rational deployment of optical fiber sensor network nodes can improve the perception effect of the Internet of things, solve the problem of covering dead angle of the Internet of things nodes, and prolong its service life. Therefore, the deployment method of optical fiber sensor network nodes based on success rate of data transmission is studied. Using evidence theory to fuse the comprehensive perception probability of the area near the network node of optical fiber sensor in the data transmission perception probability model, and to construct the network node coverage model according to comprehensive perception probability to obtain node coverage intensity. The firefly swarm algorithm is used to move the nodes with low luciferin concentration, calculate their moving probability, judge their moving direction, and finally the deployment is completed. The firefly swarm algorithm is optimized via hybrid mechanism to improve deployment performance. The experimental results show that the research method can effectively deploy the network nodes of optical fiber sensing objects and distribute evenly, effectively shorten the moving distance of nodes and reduce energy consumption. The average data transmission success rate and node coverage rate are as high as 99.6% and 100% respectively.
