路由协议的安全性是移动自组网络安全中最重要的一环
AODV路由协议因简单和控制开销小而广泛用于自组网络
但其没有任何安全机制保障
为此
本文探讨了AODV路由协议存在的主要安全隐患
对协议进行必要的改进
增加攻击检测功能
并为网络中节点建立信誉机制
二者相互作用共同完成协议安全性保障.利用NS进行仿真
结果表明改进后的算法能够检测到网络中节点的恶意行为并迅速做出反应
实现对网络内部及外部攻击的防范.
Security of routing protocols is the most important secure factor in the mobile Ad Hoc networks.AODV protocol is used widely in the Ad Hoc networks for its simplicity and small control overhead
but it does not have any security mechanism.With some potential insecure factors in AODV protocol analyzed
some necessary improvements are made to AODV protocol
including adding attack detection and building up credence mechanism
which would collaboratively guarantee the network security.Simulation results indicate that it can react quickly when some malicious behaviors in the network are detected and effectively protect the network from kinds of attacks.
