Abstract

Abstract:

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.

Key words: mobile social network, community, trust cloud, preference similarity, degree of close relationship
