摘要
Abstract
Aiming at the security problem of WMN,we propose an improved trust model ESTrust.It uses the number of interactions between observation node and evaluating node within several time periods to construct the time series,and predicts the number of interactions between the two nodes within next time period through cubic exponential smoothing method.The relative difference ratio of the predicted and actual number of interactions is used to calculate the direct trust value of the evaluating node.It introduces the entropy method to allocate the weight coefficients on the direct trust values of the evaluating node for every observation node in network,and conducts weighting operations on these direct trust values to get the synthesised trust value of evaluating node.Simulation results show that compared with AODV routing protocol and Beth trust model,the presented ESTrust model has better service quality and lower communication cost when there are malicious nodes in WMN.关键词
