随着移动Ad Hoc网络逐渐成为实现复杂战场环境信息传递的重要方式，网络安全逐渐引起重视。针对Ad hoc网络易遭受恶意节点攻击而造成大量丢包现象的安全问题，分析了目前针对移动Ad hoc网络AODV协议的几种典型的攻击模型，运用简单的缓存概念，提出了一种基于AODV的安全路由协议AODVCA，并以黑洞攻击为例，对各种性能指标进行了仿真和分析。结果表明此协议能够很好地预防和解决Ad hoc网络中恶意节点的路由攻击。

With mobile Ad Hoc network becoming the important way of delivering message in the complex battlefield circumstance,the network’s safety is attached importance.On the basis of introducing some typical attacking model of AODV protocol in the mobile Ad hoc network,this paper mainly analyses the damage to the Ad hoc network by the attacker. A security routing protocol named AODVCA based on the easy cache conception is proposed. As the example of black-hole attack,this paper simulates and analyses kinds of function index,and results obtained through simulations demonstrate that the improved protocol is better than AODV to in attack and reducing network congestion and packet loss rate.
