摘 要: 为提高无线Mesh网络面对路由攻击时的路由性能,提出一种基于模糊评判的风险评估机制。该机制通过对邻居节点的监测,获得其行为表现信息,进而采用模糊评判方法评价节点的风险值,该风险值不仅包含节点本身对目标节点的直接评价,还包含由邻居节点提供的间接评价,保证了评估结果的全面性和准确性。仿真结果表明,该算法能够准确、有效地评估节点的安全状态,实现路由的安全保障,从而提高网络的性能。

Abstract: In this paper, we proposed a risk evaluation mechanism based on fuzzy evaluation, which can improve the routing performance under the attacks in wireless Mesh networks. In this mechanism, every node monitors its neighboring nodes to obtain information about their behavior and then evaluates their risk values by using fuzzy comprehensive evaluation method. A node achieves the final risk value of the target node by integrating the evaluation of the node itself and its neighboring nodes, which can ensure the comprehensiveness and accuracy of the evaluation results. The simulation results show that the mechanism can accurately evaluate the security state of nodes, secure the routing and get a better network performance.
