摘　　要：移动自组网络拓扑结构的开放性和动态性使得传统的路由协议容易受到恶意节点的各种攻击。文章提出一个直接信任与推荐信任相结合的信任计算模型。通过基于波动的系统云灰色预测模型计算直接信任,利用不同类型的推荐节点计算推荐信任,动态确定直接信任与推荐信任的权重得出总信任值。以该信任模型为基础,文章设计了基于波动识别的可信组播路由协议BTCMRP。该协议通过信任计算可以识别并排除网络中的恶意节点,有效应对路由攻击。在路由维护中提出了转发组节点复用机制,解决了多源网格结构中组播路由开销过大的问题。仿真结果表明,与已提出的基于信任的组播路由相比,BTCMRP协议提高了投递率,降低了路由开销和平均延时。Due to the openness and dynamic natures of the mobile ad hoc network topology,traditional routing protocols are vulnerable to various attacks from malicious nodes.This paper proposes a trust calculation model combining direct trust with recommendation trust.Direct trust is calculated by fluctuation-based system cloud grey prediction model,recommendation trust is calculated by different types of recommendation nodes,and the weights of direct trust and recommendation trust are determined dynamically to get the total trust value.Based on this trust model,this paper designs a fluctuation-based trust multicast routing protocol BTCMRP.The agreement can identify and eliminate malicious nodes in the network through trust calculation,and effectively deal with routing attacks.In routing maintenance,the forwarding group node reuse mechanism is proposed,which solve the problem of excessive multicast routing overhead in multi-source grid structure.The simulation results show that compared with the proposed trust-based multicast routing,BTCMRP improves the delivery rate and reduces the routing overhead and average delay.
