%X 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.
