Closing the connectivity gap between rural and urban areas is a challenging task. However, it is an excellent opportunity for digital innovation and for boosting the development and implementation of new networking technologies. In this demo proposal, we introduce two software utilities that, when used in conjunction, ease the design and evaluation of networking scenarios based on Flying Ad Hoc Networks (FANETs). They also allow the implementation and application of multiple optimization techniques to solve the microservices deployment problem for MSA-based applications in UAV networks. The evaluation of such deployments of MSA-based applications is addressed under a network emulator. Both software tools aim to provide a framework to improve the Quality of Service (QoS) of Unmanned Aerial Vehicles (UAV) based networks that allows the network operator to choose (and compare) the best method for each situation. © 2025 IEEE.

Process discovery represents a high percentage of the time demanded along the business process management lifecycle. Texts in natural language, or process descriptions, can be explored as a critical information source. Extracting information automatically from these documents is challenging due to their ambiguity and complexity. While various (semi-)automated solutions are proposed in the literature, functional code access is rare, and tool deployment is almost nonexistent. This research introduces an accessible web interface that allows users to upload process descriptions and interact with the text, automatically identifying the main process elements from the Business Process Model and Notation. Interactions include highlighting elements associated with specific participants. An evaluation experiment with ten potential real-world users was conducted to assess the tool's benefits. The experiment compared performance in answering questions related to process descriptions across three scenarios: using plain text, using the proposed tool, and using ChatGPT. Results indicated an advantage in using the tool, particularly regarding time consumption. Data collected on ChatGPT usage also provided insights into how users leverage this technology for problem-solving. © 2025 The Author(s).

During the last years, applications requirements have been changing and the Information and Communication Technology (ICT) sector had to evolve and explore new solutions to approach the requirements of applications of the future such as telepresence, augmented reality, metaverse, holoportation, etc. One of the aspects that could serve as a basis to satisfy the stringent QoS requirements of the applications of the future is the reduction of the latency caused by TCP retransmissions. Through the proactive location of a novel network function, namely Transport Assistant (TA), the delay caused by TCP retransmissions is reduced, thus improving the network QoS and satisfying the QoS required by the applications. In this paper, a Machine Learning solution based on Logistic Regression (LR) is proposed to predict which is the part of the network that is prone to negatively impact the network performance. Through experiments based on the training of historical data, the LR-based solution is able to predict the correct location of the TA with a precision average of 95% and accuracy of 90%. Such good results in the prediction help to make better decisions and therefore to save time and resources, improving the network management. © 2023 IEEE.

In recent years, the number of devices connected to the Internet (and hence the data traffic) has significantly increased. The adoption of the Internet of Things paradigm, the use of the MicroServices Architecture for applications and the possibility of deploying such applications at different layers (fog, edge, cloud), makes the selection of an appropriate deployment a critical task for network operators and developers. In this paper, an emulation framework is proposed to allow them make a decision for the network, computing and application deployment in the cloud continuum, while satisfying the required Quality of Service. The framework is compatible both for IP and SDN network paradigms and is extensible to different types of scenarios thanks to its approach based on Docker containers. The evaluation over a realistic network scenario shows that it is extensible to any scenario and deployment required by the research community working on the cloud continuum. © 2023 IEEE.

New trends in software development have proposed different interaction mechanisms for software applications. For instance, the Software as a Service (SaaS) model has defined a new delivery and access method, and installation and update processes in the user's computer are not required, software is hosted in a server and can be used over Internet instead. Middleware platforms are required in SaaS frameworks in order to support software services. Currently, web applications are taking full advantages of SaaS benefits, because they can be delivered over Internet and developed according to a service model. However, web applications are still under a maturity process and a low degree of efficiency and reusability are achieved. This paper proposes a web service-based framework according to component software engineering (CBSE), with the aim of developing efficient and reusable web applications. Moreover, web services are the middleware technology that provides full accessibility for this type of components. © 2011 IEEE.

The Internet is the most powerful engine for social and economic growth, and it needs to be accessible to everybody. However, the possibilities for people living in rural areas to use digital services through broadband access are reduced compared to the inhabitants of urban zones. In this paper, digital services are brought closer to people living in rural areas where there is lack of Internet connectivity by means of an Unmanned Aerial Vehicle (UAV) based network. Decomposing loT applications into microservices and deploying them into UAV s allow to reduce their latency and hence to improve the associated quality of service, which is strict for this type of applications. Simulation results show the effectiveness of the proposed solution, comparing the latency experienced by the applications in case there is lack of Internet connectivity with the situation in which one of the UAV s is able to reach a ground base station. © 2022 IEEE.

Under the auspices of the most recent education legislation, teachers are urged to apply competence-based evaluation to monitor students' progress towards the effective acquisition of key competences. As students have different learning needs and develop key competences at their own pace, we propose an alternative approach that would help teachers register students' tasks and evaluate them against such competences within an eportfolio that in turn forms part of an e-learning platform. In addition to this evaluation, the integration of support tasks adapted to each student's needs could encourage acquisition and independent learning. © 2012 IEEE.
