Abstract: As a new network technology, wireless sensor network is a hot research field at home and abroad. It is a new network technology, which can collect the data information distributed on the network in real time, and transmit the information to the gateway node, and finally complete the complex network monitoring and tracking work. In order to solve the challenges faced by wireless sensor networks, for the problem of target coverage in wireless sensor networks, considering the exponential distribution of unknown random event parameters, the monitoring quality of random events is statistically analyzed, and the coverage problem is optimized under the background of wireless sensor networks. Firstly, the background and current situation of wireless sensor network are introduced. The purpose of this paper is to analyze the monitoring quality of wireless sensor network. Secondly, the coverage of wireless sensor network is optimized, the corresponding network model is established, and the optimized simulated annealing algorithm is designed. Combined with statistical knowledge analysis, the monitoring quality is studied by parameter estimation. Finally, the rationality and effectiveness of the method proposed in this paper are verified by the simulation experiment, and the purpose of prolonging the network lifetime is finally achieved.
