“…In this section, we explain the basic working environment in nursing homes and their motivation, which is crucial to conduct our study. Then, we describe previous works [2,[7][8][9][10] and explain the requirements for the development of our proposed system, as described in Section 3.

“…To realize the above system, it is necessary to monitor a resident in the nursing home. First, as a prototype system, we presented a novel system [7,8] in which users have BLE beacons and installed scanners on the environment side. In this system, we divided a nursing home into several areas and installed scanners in each one.…”

As the world’s population of senior citizens continues to grow, the burden on the professionals who care for them (carers) is also increasing. In nursing homes, carers often write daily reports to improve the resident’s quality of life. However, since each carer needs to simultaneously care for multiple residents, they have difficulty thoroughly recording the activities of residents. In this paper, we address this problem by proposing an automatic daily report generation system that monitors the activities of nursing home residents. The proposed system estimates the multiple locations (areas) at which residents are situated with a BLE beacon, using a variety of methods to analyze the RSSI values of BLE signals, and recognizes the activity of each resident from the estimated area information. The information of the estimated activity of residents is stored in a server with timestamps, and the server automatically generates daily reports based on them. To show the effectiveness of the proposed system, we conducted an experiment for five days with four participants in cooperation with an actual nursing home. We determined the proposed system’s effectiveness with the following four evaluations: (1) comparison of performance of different machine-learning algorithms, (2) comparison of smoothing methods, (3) comparison of time windows, and (4) evaluation of generated daily reports. Our evaluations show the most effective combination pattern among 156 patterns to accurately generate daily reports. We conclude that the proposed system has high effectiveness, high usability, and high flexibility.

The Internet of Things (IoT) has recently revolutionized the concept of connectivity from humans to surrounding objects through the Internet infrastructure. To Enable the wide range of IoT use cases, several communication technologies are introduced. Among the others, short range radio technology is an essential part of IoT for enabling the local area networks. Bluetooth Low Energy (BLE) version 5 is recently developed by Bluetooth Special Interest Group (SIG) which claims to be better suit for IoT use cases. However, the complexity of BLE 5 protocol and the lack of system-level simulator hinder the detailed analytical study of this new technology. To this end, we develop comprehensive system-level tool for simulating BLE 5. Some of the most important features of BLE 5 are developed and results are investigated in this paper. We investigate the BLE 5 with new physical (PHY) layer from networking perspective by analyzing end-to-end delay, battery life time, packet error rate and throughput in open office environment. To this end, we investigate the scalability of the network for different PHYs. The results show that, in this case study, the coded PHYs have weaker performance when network becomes congested.

“…The number of these devices has significantly increased compared to the world population, and by 2020 it is predicted that the number of devices connected to the internet will reach 50 billion [1]. It is common to see the smartphone applications used for transferring data from sensors to the central device [3,10,21]. However, large-scale approaches, like hospitals or smart cities, require more than standalone smartphone applications.…”

BLE (Bluetooth Low Energy) technology is an ideal tool for implementing IoT (Internet of Things) applications, as it consumes little power and provides wireless communication. There are many applications using this technology already available on the market. These products are classified as personal applications while using the BLE-supported tablets or smartphones for transmitting data and are not institutional. There are numerous studies showing that the number of IoT sensors and devices will increase rapidly. However, personal approaches cannot manage a large number of devices. In this study, a BLE gateway device which interconnects BLE and WiFi networks was developed. This device is also capable of transmitting IoT node information to a server or cloud on the Internet. The proposed design uses only BLE and WiFi stack chips and does not require an additional microcontroller unit for running gateway applications. This makes the design cost-effective and power efficient, which are important for the IoT environment.
