摘要
传统的路由安全机制并不能适用于分布式协作的移动社交网络路由协议的设计。针对该问题,文章给出了一种基于社区的移动社交网络安全路由算法SRAC。首先,采用信任云模型计算出节点间基于社区的综合信任度;然后,给出节点间基于社区的偏好相似度,通过分析节点间的相遇信息计算出相互的联络紧密度,并综合偏好相似度与联络紧密度得出节点间的关系亲密度;最后,根据移动节点间的综合信任度和节点间的关系亲密度,设计移动社交网络的安全路由算法。实验结果表明,路由算法SRAC能够有效地抑制恶意节点对消息路由的影响。
The traditional routing security mechanism is not suitable for the design of routing protocols in distributed cooperative mobile social network. In view of the problem, a security routing algorithm of mobile social network based on community(SRAC) is proposed. Firstly, the comprehensive trust between node in the same community is calculated based on cloud model. Then, the preference similarity between nodes based on the community is given, the degree of compactness between nodes is computed by analyzing the contact in-formation, and the degree of close relationship between nodes is computed by synthesizing the preference similarity and the degree of compactness. In the end, a security routing algorithm of mobile social network is designed by synthesizing the comprehensive trust and the degree of close relationship between nodes. The results of simulation show that, the routing algorithm SRAC can effectively restrain the influence of ma-licious nodes on the routing of messages.
