| 摘 要： | AODV(Ad hoc on-dem and d istance vector)路由协议效率高,控制开销小,操作简单,但本身没有任何安全机制,对安全性攻击尤其是黑洞攻击表现脆弱。针对该问题,文中在详细分析了AODV路由协议的运行原理和数据黑洞攻击问题实质的基础上对AODV协议进行了改进。利用G loMoS im仿真工具对改进的AODV路由协议进行了仿真实验,结果表明,该方案可以有效的解决数据黑洞攻击问题,同时不会过多地增加时延和协议开销。

| Abstract: | AODV(Ad hoc on-demand distance vector) routing protocol is widely used in Mobile Ad hoc networks for its high efficiency,small control overhead and simplicity.But it does not have any born security mechanism,and is vulnerable to security attacks especially the black hole attack.In this paper the working processes of AODV routing protocol and the essence of black hole attack are analyzed in detail,and a solution to Black Hole Attack is proposed.The performance of the security enhanced AODV protocol is simulated by using GloMoSim simulation tool.The results of the simulation show that the security enhanced solution can solve the problem about black hole attack effectively with relatively lower time delay and processing overhead. |
