通信与传感相遇的数据辅助传感:介绍

Data-aided Sensing where Communication and Sensing Meet: An Introduction

Jinho Choi

摘要:

由于有许多物联网(IoT)应用需要从大量传感器或设备实时收集数据集,因此需要集成传感和通信,以便从设备高效上传。在本文中,我们介绍了数据辅助感测(DAS)的概念,其中基站(BS)利用已经上传的数据的子集,并可用于选择下一个设备进行有效的数据汇集或感测。因此,使用DAS,物联网应用程序中的某些任务(包括联邦学习)可以通过从少量选定设备上传来完成。考虑两种不同类型的DAS:一种是集中式DAS,另一种是分布式DAS。在集中式DAS中,BS决定上传顺序,而在分布式DAS中,每个设备可以决定何时在多个上传轮中上传其自己的本地数据集。在分布式DAS中,采用随机接入,其中每个设备的接入概率根据其本地测量来决定,以实现高效上传。

英文摘要:

Since there are a number of Internet-of-Things (IoT) applications that need to collect data sets from a large number of sensors or devices in real-time, sensing and communication need to be integrated for efficient uploading from devices. In this paper, we introduce the notion of data-aided sensing (DAS) where a base station (BS) utilizes a subset of data that is already uploaded and available to select the next device for efficient data collection or sensing. Thus, using DAS, certain tasks in IoT applications, including federated learning, can be completed by uploading from a small number of selected devices. Two different types of DAS are considered: one is centralized DAS and the other is distributed DAS. In centralized DAS, the BS decides the uploading order, while each device can decide when to upload its own local data set among multiple uploading rounds in distributed DAS. In distributed DAS, random access is employed where the access probability of each device is decided according to its local measurement for efficient uploading.
