DSR协议下3种攻击的影响比较与仿真研究

针对移动Ad Hoc网络的动态拓扑容易遭受各种网络攻击的特点，研究和比较现有的多种攻击模型，在动态源路由(DSR)协议下提出将黑洞节点按主动攻击和被动攻击进行分类的方法。在NS2网络仿真平台上实现包括RREQ洪泛攻击、被动型黑洞攻击和主动型黑洞攻击在内的3种攻击模式。通过仿真实验评估和比较这3种攻击对网络性能的影响，得出结论，就破坏性而言，RREQ洪泛攻击强于黑洞攻击，而主动型黑洞攻击强于被动型黑洞攻击。

Impact Comparison and Simulation Research of Three Attacks Under DSR Protocol

This paper compares several attack 'models aiming at mobile Ad Hoc network's prosperity of routing vulnerable, and presents a classification that divides black hole attacks into two specific types, such as passive black hole attacks and active black hole attacks under Dynamic Source Routing(DSR) protocol. It implements three attack patterns, including the RREQ flooding attacks, the passive black hole attacks and the active black hole attacks, on DSR protocol using the Network Simulator 2(NS2). It demonstrates different performances of the network under these attacks and compares their fatality, so as to draw the conclusion that RREQ flooding attack is more harmful than the two kinds of black holes, and additionally, among black hole attacks, an active one is more dangerous.
