Editor: Mateus-Coelho, Nuno; Cunha, Maria Manuela Cruz Resumo: The Internet of Things is nowadays available everywhere, collecting data that can be used for different purposes. These end-devices are available in different formats, and depending on the use case, they need different features in order to function properly. Due to their specific requirements, some of these devices need to be portable, so a battery is an important component. Additionally, choosing the right communication protocol for these particular use cases is essential for establishing a network connection while minimising energy consumption. This will ensure that the collected data is transmitted for further analysis. This paper aims to provide an overview of LoRa, LoRaWAN, and Duty Cycling, along with their advantages and disadvantages in terms of energy efficiency on Internet of Things devices. Lastly, a suggested architectural design is proposed based on an energy-efficiency strategy, and some scenarios are assessed and compared in order to determine which could be preferred when it comes to an energy efficient solution.

M.; Coutinho, C. Editor: Coelho, Nuno Mateus; Cunha, Maria Manuela Cruz Resumo: Public cloud services consist of infrastructure, platforms or software hosted by third-parties which are made available over the Internet to end users. Organizations have adopted cloud services when selecting new applications or migrating application workloads to cloud providers, mainly because of their flexibility, scalability, and low entry cost. Security has been a topic of debate because of privacy concerns and the public cloud's inherent exposure to the Internet. The current work intends to assess how cloud services can be a strategic tool in improving an organization's cybersecurity posture. Not only some attack vectors can be reduced but cyber resilience can be setup faster using readily available cloud services. In this article we perform a systematic literature review on these topics, and design a decision support system to help application architects select cloud services from different Cloud Service Providers and make the best use of them to improve an organization's security posture and cyber resilience.

M.; Coutinho, C. Editor: Mateus-Coelho, Nuno; Cunha, Maria Manuela Cruz Resumo: Small and medium-sized enterprises (SMEs) are increasingly vulnerable to cybersecurity threats, risking their operations and growth. This paper examines SMEs' specific weaknesses and identifies effective protection strategies. Combining quantitative tests and qualitative surveys and interviews, the study highlights key challenges like limited resources, lack of expertise, and emerging technology threats. It investigates the impact of quantum computing, which could compromise current encryption methods, and Artificial Intelligence (AI), which can enhance threat detection. The findings guide SMEs in adopting new technologies, improving employee training, and bolstering cybersecurity. The paper aims to develop tailored cybersecurity plans to ensure SMEs' safety and success in the digital age.

Editor: Mateus-Coelho, Nuno; Cunha, Maria Manuela Cruz Resumo: Water, an essential resource for both human life and industry, is at risk due to overconsumption, pollution, and climate change. Addressing this issue, this research presents the development of a multiparameter monitoring and control system using Internet of Things (IoT) technology. Combining several sensors, including a camera for reading water meter values, a soil humidity sensor, and a conventional water leak detector, the system aims to detect and prevent water leaks, thereby contributing to water conservation. Furthermore, the system will integrate real-time weather data to provide a comprehensive solution for both indoor and outdoor settings. Initial implementation includes the water detection and humidity modules, with ongoing efforts to integrate the water meter module and refine the system using meteorological data. This holistic approach not only mitigates water waste but also promotes efficient water usage and raises user awareness. This research holds significant potential for several applications, offering both economic and environmental benefits.
