针对内部攻击的DSR安全性研究

Security Research of DSR against Internal Attacks

防御各种攻击是Ad Hoc网络面临的艰巨任务,针对Ad Hoc网络路由协议DSR提出一种基于邻居节点信任度机制的改进协议CT_DSR,它包括信任度管理和路由测试.仿真实验表明,改进协议CT_DSR和协议DSR相比,在牺牲少量的延迟和路由开销的情况下得到较好的网络稳定性.

Prevent various attacks is one of the most challenging tasks of Ad Hoc networks.An improved protocol named CT_DSR is proposed in this paper based on a neighbors-trust mechanism especially for the Ad Hoc networks routing protocol named DSR.CT_DSR includes credibility management and routing test.Experimental results show that CT_DSR gets better network stability than DSR.
