Abstract

In this paper, an overlapping-resistant Internet of Things (IoT) solution for a Bluetooth Low Energy (BLE)-based indoor tracking system (BLE-ITS) is presented. The BLE-ITS is a promising, inexpensive alternative to the well-known GPS. It can be used in human traffic analysis, such as indoor tourist facilities. Tourists or other customers are tagged by a unique MAC address assigned to a simple and energy-saving BLE beacon emitter. Their location is determined by a distributed and scalable network of popular Raspberry Pi microcomputers equipped with BLE and WiFi/Ethernet modules. Only simple triggered messages in the form of login records (LRs) are sent to a server, where the so-called path vectors (PVs) and interest profile (IPr) are set. The authors implemented the prototype and demonstrated its usefulness in a controlled environment. As it is shown in the paper, the solution is highly overlap-resistant and mitigates the so-called multilocation problem.

摘要

本文提出了一种基于蓝牙低能（BLE）的室内跟踪系统（BLE-ITS）的抗重叠物联网（IoT）解决方案。BLE-ITS 是 GPS 的一种很有前途、价格低廉的替代品。它可以用于人流量分析，例如室内旅游设施。游客或其他客户通过分配给简单节能的 BLE 信标发射器的唯一 MAC 地址进行标记。他们的位置由配备 BLE 和 WiFi/Ethernet 模块的流行树莓派微型计算机的分布式和可扩展网络确定。只有简单的触发消息以登录记录 (LR) 的形式发送到服务器，在服务器中设置所谓的路径向量 (PV) 和兴趣简档 (IPr)。作者实现了该原型，并在受控环境中证明了其有用性。如本文所示，该解决方案具有高度的抗重叠性，并缓解了所谓的多位置问题。
