Intelligent Deployment Method of Wireless Sensor Network Edge Nodes for Smart Classroom
In order to reduce the communication delay after deployment and improve the efficiency of data transmission and network use in smart classrooms,an intelligent deployment method of wireless sensor network edge nodes for smart classrooms is proposed.As the optimization goal of good communication in the smart classroom scenario,the objective function of intelligent de-ployment of edge nodes is built to minimize the cost of deploying edge nodes,set the traffic constraints,data flow constraints and node computing capacity constraints for the objective function,adaptively adjust the inertia weight,particle update speed and Pareto opti-mal solution preservation strategy of the particle swarm optimization algorithm,design a multi-objective improved particle swarm opti-mization algorithm to solve the objective function,and achieve the intelligent deployment of wireless sensor network edge nodes for smart classrooms.The test results show that the minimum network latency and data transmission latency of this method are 0.97 s and 0.14 s respectively when the optimization objective is network coverage;When the optimization objective is node security connec-tivity,the maximum network delay is 1.68 s,and the maximum data transmission delay is 0.68 s;The overall connectivity is high,with no missing nodes;The average network computing power is 250.55 MB/s;When the edge nodes in the wireless sensor network is 2 000,it tends to stabilize,with the time complexity of 3 times.In summary,the proposed method has lower latency,better de-ployment,and better performance,ensuring the communication and transmission quality of the smart classroom wireless sensor net-work.
