    Opis:
    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.

    Opis:
    In this paper, an autonomous wearable sensor node is developed for long-term continuous healthcare monitoring. This node is used to monitor the body temperature and heart rate of a human through a mobile application. Thus, it includes a temperature sensor, a heart pulse sensor, a low-power microcontroller, and a Bluetooth low energy (BLE) module. The power supply of the node is a lithium-ion rechargeable battery, but this battery has a limited lifetime. Therefore, a photovoltaic (PV) energy harvesting system is proposed to prolong the battery lifetime of the sensor node. The PV energy harvesting system consists of a flexible photovoltaic panel, and a charging controller. This PV energy harvesting system is practically tested outdoor under lighting intensity of 1000 W/m². Experimentally, the overall power consumption of the node is 4.97 mW and its lifetime about 246 hours in active-sleep mode. Finally, the experimental results demonstrate long-term and sustainable operation for the wearable sensor node.

    Opis:
    Promoting the use of public transport is increasingly urgent in our society, both to reduce traffic congestion, air pollution and stress levels, and to ensure the high level of mobility demanded by citizens. The lack of continuous on-trip assistance for public transport users discourages many travellers. Thus, the main objective of this work is to design a personal digital travel companion for outdoor location and event detection based on Bluetooth Low Energy, which can be used for intelligent transport technology. After analysing the functional requirements, the proposal is implemented as a mobile application for beacon-based event detection. The system includes an algorithm aided by fuzzy logic to determine the action to be carried out by the user at all times, being able to distinguish between different possible events when more than one beacon is detected. To defend the scheme against possible attacks based on beacon forgery or user tracking, the proposal includes different forms of authentication for data sent from beacons and data sent from the mobile application. The results obtained in simulations show that the proposed system is a viable guidance solution for public transport, including energy saving as one of its main advantages.
