Abstract: Currently, trust evaluation models mainly research the trust of nodes communication and few of these models research the trust of data consistency. However,trust evaluation of data consistency requires that sensing area happens only one event in a period of time,otherwise events can not be distinguished from each other accurately and legitimate node may be mistaken as malicious nodes. To resolve this problem, we proposed a method of trust evaluation of data consistency which is suitable for multi-event is concurrent. Simulation results show that, when multi-event is concurrent in sensing area, networks can distinguish events from each other accurately. It also can discover and exclude malicious nodes and reduce the false positive rate.
