Wireless jamming has been a long-standing issue both in critical infrastructure research and real-world applications, with particular importance in systems that deal with long communication distances and low received signal strength. Air traffic control is one such system, experiencing a rising number of reports of outside interference with the underlying wireless technologies. In this article, we discuss the particular issue of malicious wireless jamming on crowdsourced networks of low-cost ADS-B receivers, which increasingly support modern air traffic management. Using both simulation and laboratory trials, we first show the practical impact of reduced reception and coverage of typical receivers in a crowdsourced sensor network. Following this, we investigate network-wide countermeasures based on redundant coverage, which can defend at most 50.74% of the evaluated real-world network. To improve jamming resilience in nonredundant areas, we analyze and implement a low-cost multichannel receiver and show that it can effectively recover up to 50% of the messages even under heavy jamming conditions.

论众包空中交通监控中的干扰攻击


无线干扰一直是关键基础设施研究和实际应用中长期存在的问题，在处理长通信距离和低接收信号强度的系统中尤其重要。空中交通管制就是这样一个系统，有关外部干扰底层无线技术的报告越来越多。在本文中，我们讨论了低成本 ADS-B 接收器众包网络上恶意无线干扰的特殊问题，这些接收器越来越支持现代空中交通管理。通过模拟和实验室试验，我们首先展示了众包传感器网络中典型接收器的接收和覆盖范围减少的实际影响。随后，我们研究了基于冗余覆盖的全网对策，最多可以防御所评估的真实网络的 50.74%。为了提高非冗余区域的抗干扰能力，我们分析并实现了一种低成本多通道接收器，结果表明，即使在严重干扰条件下，它也能有效恢复高达 50% 的消息。
