In order to meet the requirements of data transmission reliability, a geotechnical environment security monitoring system based on wireless sensor network is proposed. The optimization control strategy uses the deadline miss rate as the QoS performance evaluation index. For the data transmission between the sensor node and the coordinator node, the PID controller is used to calculate the network bandwidth requirement of all sensor nodes, and then the system optimal problem is solved to realize the dynamic. The transmission period of the sensor node is adjusted to maintain the deadline miss rate at a normal set level, thereby improving the QoS of the network. Experiments show that the optimized control strategy improves the performance of the system and has good practicability in geotechnical environmental safety monitoring.
