摘要
恶意节点在一段时间内发送相当数量的RREQ消息,正常节点则广播入侵节点的RREQ信息,从而造成正常节点能源、存储资源和网络带宽耗尽,网络遭受破坏。研究了AODV路由协议的缺陷,针对路由请求RREQ消息广播的特性,实现了RREQ泛洪攻击。用NS对攻击过程进行仿真实验,用网络性能的两个重要变量(数据分组递交率和网络延迟)来衡量攻击结果。实验证明,RREQ泛洪攻击十分有效。
This paper studied the vulnerabilities of AODV routing protocol.Based on route request RREQ message and its broadcast features,the paper realized the RREQ flooding attack.Invasion node sent a number of RREQ frames every second,other normal nodes broadcast RREQ information of Invasion node to the all network so that the power,the cache and the bandwidth of normal node were exhausted.The network didn't work normally.In the paper,attack process was simulated by NS.Two variables were measured,packets delivery rate and network delay.The simulation results proved that the RREQ flooding attack method can damage the network effectively.
