Abstract

Ambient backscatter communication (AmBC) has recently attracted a lot of attention as a solution for next-generation internet of things (IoT) applications due to its capability to interact with peer devices with extremely little power usage (in μW). Security being a major concern in IoT applications, we look at the AmBC system from a physical layer security standpoint. In this paper, we focus on a realistic scenario in which numerous tags, a multi-antenna reader, and a multi-antenna eavesdropper are present, and the nodes are in motion concerning each other. The influence of speed, estimation error, number of antennas at nodes, and number of tags on the AmBC system's secrecy performance in terms of secrecy outage probability and intercept probability is investigated. Finally, the theoretical findings are supported with Monte-Carlo simulations.

带有移动节点的通用多标签、多天线环境反向散射分析：物理层安全视角

环境反向散射通信（AmBC）作为下一代物联网（IoT）应用的一种解决方案，最近引起了广泛关注，因为它能以极低的功耗（单位：μW）与对等设备进行交互。安全是物联网应用中的一个主要问题，因此我们从物理层安全的角度来研究 AmBC 系统。在本文中，我们将重点放在一个现实场景中，即存在众多标签、一个多天线读取器和一个多天线窃听器，并且节点之间相互运动。本文研究了速度、估计误差、节点天线数量和标签数量对 AmBC 系统保密性能的影响，包括保密中断概率和拦截概率。最后，用蒙特卡洛模拟支持了理论研究结果。

期刊介绍： Vehicular communications is a growing area of communications between vehicles and including roadside communication infrastructure. Advances in wireless communications are making possible sharing of information through real time communications between vehicles and infrastructure. This has led to applications to increase safety of vehicles and communication between passengers and the Internet. Standardization efforts on vehicular communication are also underway to make vehicular transportation safer, greener and easier. The aim of the journal is to publish high quality peer–reviewed papers in the area of vehicular communications. The scope encompasses all types of communications involving vehicles, including vehicle–to–vehicle and vehicle–to–infrastructure. The scope includes (but not limited to) the following topics related to vehicular communications: Vehicle to vehicle and vehicle to infrastructure communications Channel modelling, modulating and coding Congestion Control and scalability issues Protocol design, testing and verification Routing in vehicular networks Security issues and countermeasures Deployment and field testing Reducing energy consumption and enhancing safety of vehicles Wireless in–car networks Data collection and dissemination methods Mobility and handover issues Safety and driver assistance applications UAV Underwater communications Autonomous cooperative driving Social networks Internet of vehicles Standardization of protocols.
