摘要
针对移动Ad hoc网络的特点,信任机制被提出并广泛应用,以保障网络的安全性。通过对现有信任模型的研究,一种基于模糊逻辑的信任模型被提出来。该信任模型中影响信任的因素包括节点的独特性,节点的稳定性和节点的历史行为。通过对各因素的模糊化,推理其对应的输出值,并计算各因素的权值分配,最后综合各输出值计算出节点的信任值,根据该信任值帮助节点做出信任决策。
According to the characteristics of mobile Ad hoc network, trust mechanisms have been proposed and widely used to protect the security of the network. After studying on the current trust models, this paper proposes a new trust model based on fuzzy logic. Factors which affect trust in the model include the unique nature of the nodes, the stability of nodes and the historical behavior. These factors will be calculated to output values by fuzzification. Using the weight distribution, the output values will be aggregated into the last trust value. Nodes can make the trusting decision with the help of the trust value.
