摘要

物联网（IoT）已广泛应用于各个工业领域。为了在基于物联网的应用中实现超自动化，需要高效的无线传输技术来提高物联网节点的响应速度。频域竞争（FDC）是一种很有前途的基于竞争的信道接入机制来满足这一要求。然而，FDC的多传输多接收特性和物联网芯片同步精度的限制将导致载波频率偏移（CFO），从而导致频繁的传输冲突和零传输。考虑到整数和分数CFO，本文从理论上分析了FDC吞吐量，并通过大量仿真验证了模型的准确性。

Throughput analysis of frequency-domain contention under realistic conditions for hyperautomation

ABSTRACT Internet of Things (IoT) has widely been deployed in various industrial fields. To achieve hyperautomation in IoT-based applications, it calls for high-efficient wireless transmission technologies to improve the response speed of IoT nodes. Frequency-domain contention (FDC) is a promising contention-based channel access mechanism to meet this requirement. However, the nature of FDC’s multiple-transmission-multiple-reception and the limit of IoT chip’s synchronization accuracy will lead to carrier frequency offset (CFO) and hence frequent transmission collisions and null transmissions. Considering integer and fractional CFO, this paper theoretically analyzes the FDC throughput and verifies the accuracy of our model via extensive simulations.

期刊介绍： Enterprise Information Systems (EIS) focusses on both the technical and applications aspects of EIS technology, and the complex and cross-disciplinary problems of enterprise integration that arise in integrating extended enterprises in a contemporary global supply chain environment. Techniques developed in mathematical science, computer science, manufacturing engineering, and operations management used in the design or operation of EIS will also be considered.
