摘要: 提出了一种用于车载自组网(VANETs)的可靠信任传播模型,该模型通过引入属性相似度概念在陌生节点间建立信任关系,并进一步建立了一种新的动态包转发规则,从而实现了车载自组网的可信路由, 并给出了一种计算属性相似度的推荐方法. 仿真结果表明,所提出的信任传播模型具有较高的准确性.

关键词: 车载自组网, 信任传播, 属性相似度, 路由

Abstract: A scheme to enhance trust propagation in vehicular Ad hoc networks (VANETs) is proposed. By introducing the concept of attribute similarity, the trust routing is achieved to find some potential friendly nodes among strangers. Based on similarity degree, a new forwarding behavior is put forward. Also the recommendatory methods to calculate the similarity degree of attribute are given. Simulation results show the proposed trust propagation scheme is precise.

Key words: vehicular Ad hoc networks, trust propagation, attribute similarity, route
