移动社交网中基于兴趣社区的消息传输方案

Interest Community Based Message Transmission Scheme in Mobile Social Networks

节点对路由消息的存储-携带-转发是移动社交网中的一种短距离通讯方式,传输性能是影响用户交互体验的关键因素,如果用户能够根据彼此间的兴趣或社区来进行消息传输,则可提高传输性能。目前,针对移动社交网中的短距离通讯,已有的研究主要是基于兴趣或者基于社区的传输方式。为了使用户得到更好的交互体验,将用户兴趣与社区相结合,提出基于兴趣社区的消息传输方案InComT(Interest Community based Transmission)。对移动社交网中单个节点的兴趣进行度量,根据得出的节点兴趣值进行社区划分,从而确定社区整体的兴趣值,并根据兴趣值来选择中继社区和中继节点,实现消息的传输。仿真结果表明,该策略在传输负载率和平均延时较低的情况下能够拥有较高的传输成功率。

The storage-carrying-forwarding of node for route messages is a short-distance communication way in the mobile social networks,and the transmission performance is the key factor that affects user interaction experience.If users can transmit the message according to the interest or the formation of the community,the transmission performance can be improved.For the short-distance communication in the mobile social network,the existing researches are mainly either interest-based or community-based transmission.In order to make users have a better interactive experience,this paper proposed InComT（Interest-Community-based Transmission）by combining user interest with community.The interest value of a single node in the mobile social networks was measured,the community was divided according to the its interest value to determine the whole community interest value and then the relay community and the relay node were selected by the interest value to realize the transmission of message.The simulation results show that the strategy can possess higher transmission success rate in the case of low transmission overhead and low average delay.
