摘要：
In view of the problem that the content sharing rate is low and the cost is high in mobile social networks (MSNs), which is caused by connection uncertainty between and limited network resources of users, a user similarity-aware content sharing mechanism in mobile social networks was proposed. By analyzing behavior of users, user's steady state and the change state could be perceived, and the steady state and the change state interest of user's, the interest similarity between users could be obtained. And then the user similarity and logical relationship were obtained by combining user interaction degree and user activity area similarity degree. Finally, based on the user similarity, virtual community could be established with dynamic changes of user interest, which can achieve low-cost and high success rate of content sharing. The results show that the proposed mechanism can effectively improve the success ratio of content sharing while greatly reducing the network overhead rate. © 2017, Editorial Board of Journal of Huazhong University of Science and Technology.
