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.
Highlights
Innovation in the tourism sector is linked to modern solutions such as Internet of Things (IoT), distributed sensor networks (DSN), cloud computing, mobile communication, and machine learning [1]
The measurement was repeated for three different beacon interval (BI): 0.32 s (2690 analyzed received signal strength indication (RSSI) values), 1.28 s (672 analyzed RSSI values), and 5.12 s (180 analyzed RSSI values)
The results show a slight improvement in the signal quality for longer beacon intervals
Summary
Innovation in the tourism sector is linked to modern solutions such as Internet of Things (IoT), distributed sensor networks (DSN), cloud computing, mobile communication, and machine learning [1]. Smart tourism should provide tour information and tour guidance services before, during, and after the trip. It requires the implementation of additional solutions to support the process of their development. Two main groups of requirements for smart tourism solutions can be distinguished. The first group is related to customers (visitors). They should be able to remotely plan a specific date and route of the tour and to obtain proposed paths of seeing and basic information about expositions, as well as weather forecasts or free parking places. An appropriate tour report including the tourist’s profile of interest and related information would be appreciated after a finished visit
