移动自组网中一种基于模糊集合的分层信任模型

摘要

提出一种基于模糊集合的分层信任模型.该模型采用模糊集合对信任关系进行建模,引入向量贴近度为推荐信任分配权重,并充分考虑分层(分簇)结构移动自组网的特点,强调了系统的可扩展性、动态适应性、鲁棒性和资源开销最小.%This paper presented a hierarchical trust model based on the fuzzy set theory. It used fuzzy sets to model the trust relationships,introduced vector closeness degree for distributing the weights of recommendation trust, fully considerated the characteristics of hierarchical(clustering) mobile Ad hoc networks, and emphasis on characteristics of adaptability, robustness and resource-saving.
