摘要:
无线自组织网络是开放的合作式网络,并且可以在没有任何复杂的基础设施前提下迅速形成网络结构。这种易用性使得众多移动节点需要通过自组织网络进行通信。然而,对于移动自组织网络同时也存在大量的安全威胁。泛洪攻击和黑洞攻击是在移动自组织网络中两种有代表性的典型威胁。重点研究了通过使用两种攻击方式在不同条件下对使用AODV路由协议的移动自组织网络进行模拟攻击,同时采用阻断消息传输和泛洪预防手段进行相应的网络防御。最后,对丢包率、网络延时、路由开销等参数在NS-3网络模拟器中进行测试。实验结果表明,通过不同攻击方式采用相应的防御策略可以改善网络性能抵御攻击行为。

Abstract:
Mobile ad hoc networks are open and cooperation networks, and can quickly form a network structure in the absence of any complex infrastructure premise. This ease of use makes a number of mobile nodes need to communicate via an ad hoc network. However, there are large numbers of security threats for mobile ad hoc networks. Flood attacks and the black hole attacks in the mobile ad hoc network are two threats which are representative and typical. By using two kinds of attacks in different situations using AODV routing protocol for mobile ad hoc network simulated attacks, while using avoiding message transmission able and flood attack prevention means corresponding network defense. Finally, the packet loss rate, network delay, routing overhead and other parameters tested in the NS-3 network simulator. Experimental results show that can improve network performance by using the appropriate defense strategy aiming at different attacks.
