利用OPNET模拟器分析AODV在黑洞攻击下的性能
Performance Analysis of AODV under Black Hole Attack through Use of OPNET Simulator
摘要：
移动自组织网络是一种动态的无线网络，没有任何基础设施。这些网络对许多类型的攻击都很脆弱。其中一种攻击就是黑洞。在这种攻击中，恶意节点将自己伪装成具有到特定节点的最新或最短路径，以将数据包吸收到自己。本研究将探讨黑洞攻击对以AODV为路由协定的Ad Hoc网路的影响。此外，我们调查的解决方案，以提高这些网络的安全性。利用OPNET仿真器进行的仿真结果表明，在存在恶意节点的情况下，数据包的投递率显著降低。
英文摘要：
Mobile ad hoc networks (MANETs) are dynamic wireless networks without any infrastructure. These networks are weak against many types of attacks. One of these attacks is the black hole. In this attack, a malicious node advertises itself as having freshest or shortest path to specific node to absorb packets to itself. The effect of black hole attack on ad hoc network using AODV as a routing protocol will be examined in this research. Furthermore, we investigate solution for increasing security in these networks. Simulation results using OPNET simulator depict that packet delivery ratio in the presence of malicious nodes, reduces notably.
