Abstract

This paper analyzes the effects of transient faults implemented by power supply disturbance (PSD) fault injection method on a narrowband internet of things (NB-IoT) technology. NB-IoT is a widely used technology for wide-area applications that is providing real-time information to system operators. However, either intentional or unintentional transient faults can potentially result in inappropriate control actions, jeopardizing the security, resilience, and reliability of NB-IoT network. PSD fault injection method drops power supply voltage of NB-IoT transmitter chip for different durations and voltage levels. To connect circuit of fault injection to NB-IoT network, a host computer is programmed as a fault injection manager. In this configuration, sending packets is done through one of NB-IoT chips, and receiving them is done on server side. The results of empirical fault injections showed that the fault tolerance of NB-IoT technology needs crucial improvement. To address this issue, an active retransmission technique (ART) method is proposed. ART involves leveraging time redundancy and retransmission of particular number of packets depending on the acceptable level of reliability and performance overhead. This approach has contributed to enhancing the resilience of NB-IoT.

NB-IoT设备的可靠性框架：解决瞬态故障和静默数据损坏

分析了采用电源干扰（PSD）故障注入方法实现暂态故障对窄带物联网（NB-IoT）技术的影响。NB-IoT是一种广泛应用于广域应用的技术，为系统运营商提供实时信息。然而，无论是有意还是无意的暂时性故障，都可能导致控制动作不当，从而影响NB-IoT网络的安全性、弹性和可靠性。PSD故障注入方法在不同的持续时间和电压水平下降低NB-IoT发射芯片的供电电压。为了将故障注入电路连接到NB-IoT网络，将一台主机编程为故障注入管理器。在这种配置中，通过一个NB-IoT芯片发送数据包，在服务器端接收数据包。经验故障注入结果表明，NB-IoT技术的容错能力亟待提高。为了解决这个问题，提出了一种主动重传技术（ART）方法。ART涉及利用时间冗余和根据可接受的可靠性和性能开销级别对特定数量的数据包进行重传。这种方法有助于增强NB-IoT的弹性。
