论文摘要
在5G和Be-Beyond行业4.0的框架中，拒绝服务的攻击是一种不断上升的威胁，可以严重损害系统性能。因此，在本文中，我们处理了室内工厂部署中障碍检测和缓解的问题。我们设计了两个基于伪随机的副载体的干扰探测器，并使用正交频分多路复用，并考虑使用频率跳跃和用户设备的随机调度来解决缓解措施。然后，我们通过超可靠的低延迟通信流量和障碍物错过的检测概率来评估系统的性能。考虑到工厂地板的第三代合作伙伴项目空间渠道模型，进行了模拟，该工厂驻扎在工厂外，试图破坏工厂内部的通信。数值结果表明，使用分布式访问点部署并利用天线之间的通道相关性来掩盖检测时，弹性的弹性会提高，而频率跳跃有助于减轻缓解的方法，仅对严格的bler要求进行措施。
In the framework of 5G-and-beyond Industry 4.0, jamming attacks for denial of service are a rising threat which can severely compromise the system performance. Therefore, in this paper we deal with the problem of jamming detection and mitigation in indoor factory deployments. We design two jamming detectors based on pseudo-random blanking of subcarriers with orthogonal frequency division multiplexing and consider jamming mitigation with frequency hopping and random scheduling of the user equipments. We then evaluate the performance of the system in terms of achievable BLER with ultra-reliable low-latency communications traffic and jamming missed detection probability. Simulations are performed considering a 3rd Generation Partnership Project spatial channel model for the factory floor with a jammer stationed outside the plant trying to disrupt the communication inside the factory. Numerical results show that jamming resiliency increases when using a distributed access point deployment and exploiting channel correlation among antennas for jamming detection, while frequency hopping is helpful in jamming mitigation only for strict BLER requirements.
