Based on the IOT network model, this paper analyzes the delay characteristics of the IOT, and constructs the object function of the gateway node reconfiguration of IOT. By monotone decreasing inertia weight strategy, the coding particle swarm optimization is optimized, and the reconfiguration objective function of the gateway node of IOT by using the optimized particle swarm optimization algorithm is solved. Experimental results show that the channel utilization ratio of the proposed method is higher than 90%, the success rate of information transmission is more than 80%, and the data transmission delay is less than 0.5\u00a0s, which indicates that the proposed method has high channel utilization, high transmission success rate and low data transmission delay.<\/jats:p>","DOI":"10.3233\/web-210456","type":"journal-article","created":{"date-parts":[[2021,11,12]],"date-time":"2021-11-12T11:16:53Z","timestamp":1636715813000},"page":"27-40","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["A
