在无线自组织网络中，由于资源的限制和缺乏集中控制，建立一个有效的入侵检测系统（IDS）是一项具有挑战性的任务。在这项工作中，我们提出了一个分散的监测为基础的IDS检测干扰型拒绝服务（DoS）攻击的协议栈的低层。在ad hoc网络中，不断变化的信道和网络动态会损害类似于干扰场景的服务，从而导致入侵检测的误报。为此，我们在IDS中采用了跨层设计，以区分恶意干扰行为和真正的网络故障。我们通过仿真验证了我们的设计，并建立了模型的有效性。从仿真结果中，我们观察到检测的准确性和较低的误报率有显着提高
Building an efficient intrusion detection system (IDS) is a challenging task in wireless ad hoc networks due to the resource constraints and lack of a centralized control. In this work, we present a decentralized monitor-based IDS for detecting jamming type denial of service (DoS) attacks at the lower layers of the protocol stack. The varying channel and network dynamics in ad hoc networks can impair service similar to a jamming scenario, resulting in false positives on intrusion detections. To this end, we incorporate a cross-layer design in our IDS to differentiate the malicious jamming behavior from genuine network failures. We validate our design through simulation, and establish the effectiveness of the model. From the simulation results, we observe a significant improvement in the accuracy of detection and lower false positives
