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.
