在Ad Hoc网络中,动态拓扑及自由移动的特点使恶意节点发起各种攻击造成网络资源不可用。为此提出移动频率(MF,Mobile Frequency)评估节点移动情况。同时,在AODV的基础上,提出一个基于节点信任度和能量的路由方案,该方案中节点信任度受移动频率影响,下一跳节点的选择由信任度和能量共同决定,并通过区分可信与不可信节点,孤立恶意节点来保证路径上的节点都有足够能量并且安全可信。
In Ad Hoc network, the characteristics of dynamic topology and free movement make malicious nodes initiate various attacks and make network resources unavailable. For this reason, we proposed the Mobile Frequency (MF) to evaluate the movement of nodes. At the same time, a routing scheme based on node trust and energy is proposed based on AODV. In this scheme, the node trust is affected by the mobile frequency. The next-hop node is decided by trust and energy, And untrustworthy nodes, isolated malicious nodes to ensure that the nodes on the path are sufficient energy and safe and reliable.
