Cluster-Based Trust Evaluation Scheme in an Ad Hoc Network
移动自组网中一种基于分簇的信任评估方案

The important intent of the trust evaluation scheme is to resist the secure risk of misbehavior of node in an ad hoc network, and a cluster-based trust evaluation scheme is proposed in this thesis. The head issues a trust value certificate that can be referred to by its non-neighbor nodes. In this way, an evaluation of an unfamiliar node's trust can be done very efficiently and precisely. In this paper, we present a trust evaluation metric using this scheme and some operations for forming and managing a cluster. In contrast to the traditional schemes, it overcomes the limited information about unfamiliar nodes and reduces the required memory space. An analysis of the proposed scheme over some security problems is also presented.
