In recent years, Wifi-based localisation systems have gained significant interest because of the lack of Global Positioning System (GPS) signal in indoor and certain open areas. Over the past decade, many datasets have been introduced to enable researchers to compare different localisation techniques. Existing datasets, however, have failed to cover open areas such as parks in cases where GPS is still unavailable, and there is a lack of Wifi access points. Also, the existing datasets only focus on getting Wifi fingerprint collected and labelled by users. To the best of our knowledge, no dataset provides Received Signal Strengths (RSS) collected by Wireless Access Points (APs).
In this work, we offer two datasets publicly. The first is the Fingerprint dataset in which four users generated 16,032 accurate and consistently labelled WiFi fingerprints for all available Reference Points (RPs) in a central and busy area of Murdoch University, known as Bush Court. The second is the APs dataset that includes 2,450,865 auto-generated records received from 1000 users’ devices, including the four users, associated with Wifi signal strengths. To overcome the Wifi coverage problem for the Bush Court, we attached our previously designed Wireless Sensor Nodes (WSNs) to existing garbage bins, enabling them to provide real-time environmental sensing and act as soft APs that sense MAC addresses and Wifi signals from surrounding devices.

使用智能垃圾箱的无GPS开放区域的基于Wifi的本地化数据集
近年来,基于Wifi的定位系统引起了人们的极大兴趣,因为室内和某些开放区域缺少全球定位系统(GPS)信号。在过去的十年中,引入了许多数据集,以使研究人员能够比较不同的定位技术。但是,在GPS仍不可用且缺少Wifi接入点的情况下,现有数据集无法覆盖公园等空旷地区。此外,现有数据集仅专注于获取用户收集并标记的Wifi指纹。据我们所知,没有数据集提供无线接入点(AP)收集的接收信号强度(RSS)。
在这项工作中,我们公开提供了两个数据集。第一个是指纹数据集,其中四个用户为默多克大学中心和繁忙区域(称为布什法院)的所有可用参考点(RP)生成了16,032个准确且一致标记的WiFi指纹。第二个是AP数据集,其中包括从1000个用户的设备(包括四个用户)接收的2,450,865条自动生成的记录,这些记录与Wifi信号强度相关。为了解决布什法院的Wifi覆盖问题,我们将以前设计的无线传感器节点(WSN)附加到现有的垃圾箱中,使它们能够提供实时的环境感知,并充当软AP来感知周围的MAC地址和Wifi信号设备。
