安全路由协议设计是移动自组网所面临的重大课题之一.针对移动自组网中3种典型的安全路由协议(ARAN,Ariadne,SEAD)进行了深入研究,对其性能与特点进行了细致的比较与分析.同时,在网络模拟器ns2中实现了上述协议并进行了性能测试.实验结果显示:尽管上述安全路由协议能在一定程度上提高安全性,但其性能及额外开销随网络拓扑的动态变化也急剧变化.模拟分析结果对移动自组网中安全路由协议的设计与分析有着较好的指导意义,为相关设计打下了良好的基础.

Designing secure routing protocols is one of the most critical and challenging aspects for MANET.So far,many secure routing protocols have been proposed in recent literatures.However,little research effort has been performed for comparison and analysis of these protocols.In this paper,detailed comparison and analysis are performed for three mainstream secure routing protocols,named ARAN,Ariadne and SEAD.Also these protocols are implemented in ns2,and extensive simulations are conducted.Simulation results show that although these security routing protocols increase the security of MANET,their performance and additional costs also increase significantly with the rapid change of network topologies.The experimental and analytical results provide a fundamental and comprehensive comparison with previous safety routing protocols,and these results are also very meaningful for future designs.
