[0061] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.
[0062] The trust value management method of sensor nodes in a wireless sensor network based on IPv6 tree topology structure includes the following steps:
[0063] S1: The trust value is evaluated periodically between sensor nodes, and the period length is Δt;
[0064] S2: Each sensor node reports the evaluation result of its trust value to neighbor nodes to the data aggregation sink node;
[0065] S3: The data aggregation sink node combines the trust value evaluation results of all neighbor nodes of a certain sensor node and the trust value evaluation result of the data aggregation sink node for the sensor node according to the received trust value evaluation results;
[0066] The trust value evaluation includes at least any one or more of the trust evaluation di...
