自组织网络协议及安全性分析

Analysis on Ad Hoc Network Protocol and Its Security

作为Ad Hoc网络关键功能的路由协议的安全性一直以来都是Ad Hoc网络研究的热点问题。针对AODV协议以及Ad Hoc网络面临的威胁进行了分析,研究使用无线信道对自组织网络进行黑洞攻击的方法,并使用NS2建立自组织网络攻击仿真模型,对黑洞攻击效果进行了评估,验证了黑洞攻击的有效性,为了预防此类攻击对AODV协议提出改进建议。

As a key-function of Ad Hoe network,the routing protocol and its security are always hot research topic.This paper analyzes AODV protocol and the threat faced with Ad Hoc network, studies a method of black-hole attack for Ad Hoc network by using wireless channel,and sets up simulation model for Ad Hoc network attack by using NS2.The black-hole attack effect is evaluated, and the results prove the effectiveness of black-hole attack.For preventing these kinds of attack,this paper offers a proposal for AODV protocol improvement.
