摘要: 机会移动社群网络易受到不良节点干扰而导致正常通信中断,现有研究方法普遍存在忽略不良行为差异性,为此,提出了基于狄利克雷分布的可信路由转发机制.利用消息传递过程判断节点的可信度,提出应对干扰的路由转发机制.实验结果表明,在受到不良节点干扰的条件下,该机制能够准确评估节点,同时在保持低传输成本的情况下,传输成功率比传统方法提高了5%~10%.

关键词: 狄利克雷分布, 机会移动社群网络, 可信路由

Abstract: The opportunistic mobile social network is vulnerable to the interruption of normal communication due to the interference of bad nodes. Existing research methods generally have the problem of neglecting the difference of bad behavior. The article proposes a trusted routing and forwarding mechanism based on Dirichlet distribution. Firstly, the message passing process is used to judge the credibility of the node, and then the routing and forwarding mechanism for dealing with interference is proposed. Experiment shows that the mechanism can accurately evaluate nodes under the condition of poor node interference, and the transmission success rate is 5%~10% higher than the traditional method while keeping the transmission cost low.

Key words: Dirichlet distribution, opportunistic mobile social network, trusted routing
