摘要
无线干扰使战术Ad hoc网络面临严重安全威胁,甚至可以完全阻断网络通信,因此,急需提出适用于战术Ad hoc网络的干扰检测方法。提出了一种基于数据包重发次数和数据包传输率的战术Ad hoc网络响应式干扰检测方法,并在ns-3环境下仿真实现。仿真表明该方法可快速有效检测出干扰。
Jamming attack is the most important threaten to tactical ad hoc networks, In the wont scenario, it can completely block all network communications. Thus, New Algorithm for jamming detection is required, especially for tactical ad hoc networks. In this paper, We present a novel mechanism to detect reactive jamming in tactical ad hoc networks, which is based on the required number of re-transmission attempts of transmitted packets and packet delivery rate (PDR) of received packets. The simulation is implemented in ns-3 network simulator. Simulation indicates that jamming can be detected by our algorithm quickly and efficiently.
