中文摘要：

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。

英文摘要：

In the MANET,Malicious nodes launching various attacks would make the resources unavailable,thus MF（Mobile Frequency） is proposed to evaluate node＇s movement.Meanwhile,a security routing scheme based on trustworthiness and energy is suggested according to AODV protocol.In this scheme,the node＇s trustworthiness is affected by their MF.Trustworthiness and energy decide together the selection of next hop.And the scheme,through the distingushing of trusted and distrusted nodes,and ensures the sufficient energy and reliability of the nodes in the route path.
