- IoT system to monitor the well-being of senior citizens who self-isolate during the pandemicPublication . Gonçalves, Fábio; Jesus, Cassandra Sofia dos Santos; Fernandes, Francisco; Rosa, Rafaela; Dionísio, Rogério PaisThe COVID-19 pandemic and the need for selfisolation has decreased the frequency of visits to senior citizens by family members or caregivers. Because of this, many health concerns of the elderly remained unresolved. We created a IoT system, called Zelar@CB, that monitors the daily activities of isolated elderly people who do not have access to at-home care. The proposed project detects unusual activity by monitoring the person’s usage of electrical appliances to track if the user left the stove on or if there is a change in usage. It can also detect when the user falls, and sends an alert to family members or caregivers.

- Zelar@CB: IoT system to care for elder people living in isolated rural areasPublication . Gonçalves, Fábio; Fernandes, Francisco; Jesus, Cassandra Sofia dos Santos; Rosa, Rafaela; Dionísio, Rogério PaisBecause senior citizens are at a higher risk of suffering serious complications from COVID-19, medical officials have cautioned them to stay at home. Their family and caregivers have also cut back on visits due to fear of spreading the virus to them. This situation has left many of the elderly increasingly isolated and without anyone to keep a watchful eye on their health. Zelar@CB is a wearable monitoring system that keeps track of a person’s daily routine and alerts caregivers if it suspects something is amiss. The system detects unusual activity by monitoring the person’s usage of electrical appliances to track if the user left the stove on or if there is a change in usage. The system sends an alert to family members or caregivers if it detects that. It can also detect when the user falls. The system uses a LoRa Network, combined with a low-power wearable device that can be worn as a bracelet or embedded in clothing, and an energy monitor that connects to the user’s electrical appliances. The wearable device is equipped with an accelerometer and a gyroscope. The gyroscope can detect if the user has fallen. The energy monitor is connected to the main electrical line of the home. The system monitors the power consumption of each electrical appliance and timestamps related to the users’ daily activities. Zelar@CB also uses an artificial intelligence algorithm previously trained with data on the user’s regular consumption of power. The energy monitor uses Wi-Fi to send either an SMS or email alert, or a message through the mobile application we developed. Because the amount of data produced by the energy monitor is substantial, the monitor cannot use LoRa alone. The LoRa system implements a Fair Access Policy: 10 downlink messages and 30 seconds uplink time on air per 24 hours, perdevice. Although this is adequate for the rare fall detection events, it is not enough for regular energy consumption measurements.
- Design-With-IoT and Design-For-Automation: A Proposal for Product Development Oriented for ExcellencePublication . Dionísio, Rogério Pais; Torres, PedroThis paper presents two methodologies for the design and development of new products called Design-with- IoT (DwIoT) that aims to integrate IoT technology into products, focusing on a set of guidelines for its implementation, and the concept of Design-for-Automation (DFA), important in the development of new automation oriented products in an industry 4.0 context.
- Industrial Internet of Things – security, weaknesses and most common types of attacks: a systematic literature reviewPublication . Fabri, Vladimir; Stefanović, Miroslav; Pržulj, Đorđe; Vučković, Teodora; Dionísio, Rogério PaisIn recent years there has been a growing interest in the Industrial Internet of Things (IIoT) coming from business and scientific communities alike. One of the elementary concepts of the proposed Industry 4.0 is the IIoT which proposes the implementation of the regular Internet of Things (IoT) concept on a much larger scale within the industrial facilities, thus interconnecting devices in industrial settings. While the main focus of the scientific community is on the cost/benefit analysis and practical application of the mentioned concept, one often overlooked aspect is its security. The following paper presents a comprehensive systematic literature review for the Industrial Internet of Things security. It contains a review of the most common types of attacks committed within the Industrial Internet of Things and a consequential analysis of the weaknesses those attacks exposed.
