当前的数据驱动的智能运输系统主要依靠IEEE 802.11p来收集和交换信息。尽管IEEE 802.11p在提供低延迟通信方面的表现仍然很容易受到攻击，这仍然很容易受到攻击，因为在实践中缺乏PHY层的对策技术。在本文中，我们提出了一种新颖的接收器设计Jammingbird，可容忍强烈的恒定干扰攻击。卡明鸟的推动器是两种基于MIMO的技术：耐干同步器和抑制器。总的来说，这两个新模块能够在攻击下检测，同步和恢复所需的信号，而与干扰者采用的PHY层技术无关。我们已经在车辆测试床上实施了卡明鸟，并进行了广泛的实验，以评估其在三种常见的车辆场景中的性能：停车场（0〜15 mph），当地交通区域（25〜45 mph）和高速公路（60〜70 mph）。在我们的实验中，虽然干扰攻击将基于802.11p的传统接收器的吞吐量降低了86.7％，但Jammingbird平均维持了83.0％的吞吐量。实验结果还表明，与所需的信号相比，卡米林鸟的功率强25 dB耐用信号。
Current data-driven intelligent transportation systems are mainly reliant on IEEE 802.11p to collect and exchange information. Despite promising performance of IEEE 802.11p in providing low-latency communications, it is still vulnerable to jamming attacks due to the lack of a PHY-layer countermeasure technique in practice. In this paper, we propose JammingBird, a novel receiver design that tolerates strong constant jamming attacks. The enablers of JammingBird are two MIMO-based techniques: Jamming-resistant synchronizer and jamming suppressor. Collectively, these two new modules are able to detect, synchronize, and recover desired signals under jamming attacks, regardless of the PHY-layer technology employed by the jammers. We have implemented JammingBird on a vehicular testbed and conducted extensive experiments to evaluate its performance in three common vehicular scenarios: Parking lots (0~15 mph), local traffic areas (25~45 mph), and highways (60~70 mph). In our experiments, while the jamming attacks degrade the throughput of conventional 802.11p-based receivers by 86.7%, JammingBird maintains 83.0% of the throughput on average. Experimental results also show that JammingBird tolerates the jamming signals with 25 dB stronger power than the desired signals.
