A Routing Algorithm base on Trustworthy Core Tree for WSN£¨RATCT£© is proposed in this paper aims to prolong network lifetime as well as increase network security in a hierarchical-cluster sensor network. Cluster heads with higher residual energy and trust level are elected from underlying sensor nodes. A minimum energy consumption(More)
In order to avoid the trust evaluation information appearing flooded in the evaluation process. This paper presents a trust evaluation matrix model based on cooperation and reputation. We has analyzed the indicator characteristic of the cooperation evaluation and the reputation evaluation separately, for the reputation, we adopt the dual semantics to carry(More)
