路由攻击对移动Ad Hoc网络的影响分析

典型的移动Ad Hoc网络路由协议,如AODV等均没有考虑其安全性,面对恶意节点的攻击时,表现得非常脆弱.以拒绝服务攻击为例,对运用AODV路由协议的网络平均端对端时延、丢包率、包到达率、路由负荷等性能指标进行模拟和分析.结果表明,当网络中存在此类攻击行为时,各项性能恶化严重.因此,需要设计一种有效的安全机制,通过模拟试验来检验其对抑制攻击的有效性,并应用于AODV以外的其他路由协议之上,以增强其可移植性.

The Effect of Routing Attacks on Mobile Ad Hoc Network

The typical routing protocols of mobile Ad Hoc networks such as Ad Hoc on-demand distance vector(AODV) leave out of consideration about their security.They are very fragile when the malicious nodes attack them.The performance of average end-to-end delay,packet drop ratio,packet delivery ratio and routing load are simulated by adding the denial of service(Dos) attack on the AODV.Computer simulation results show that the network performance is deteriorated sharply if there have DoS routing attack in the Ad Ho...
