Wireless Sensor Network Technology Based on Security Trust Evaluation Model
Keywords:Trust evaluation model, Multi-factor, Bayesian model, Wireless sensor
Because the current research on wireless sensor networks is not thorough enough, with such shortcomings as lack of objectivity and insufficient accuracy of the trust evaluation model of network nodes, this paper proposes a trust evaluation model with multi-factor comprehensive consideration and Bayesian model, an improved trust evaluation model, by combining trust management mechanism, trust factor, fuzzy set and D-S evidence theory, solving factor singleness and imprecise evaluation in the original model. The simulation results show that the proposed model has good dynamic adaptability, higher detection rate and lower detection error rate, and it consumes less energy and improves the security of the network.
