Abstract: Abstract: Since there is no uniform standard to assess the reliability of Wireless Sensor Networks, a reliability evaluation model based on fuzzy neural network was proposed. Firstly, the reliability was analyzed from the point of view of the topology, protocol stack and reliability mechanism of wireless sensor networks, and the performance indexes affecting reliability were extracted. Secondly, some performance indexes were selected, and the reliability evaluation standard value matrix was established, and generating sample data by interpolation; WSN reliability evaluation model was established based on Fuzzy Neural Network. In this model, input is performance index extracted from the WSN, and output is the reliability of wireless sensor networks. Finally, according to the model program flow chart to prepare the simulation program and training model using sample data. According to the test results, the evaluation results of the reliability model are basically consistent with the actual situation. The model can evaluate the wireless sensor network from the system level.
