Although many courses in computer science and software engineering require students to work on practical assignments, these are usually toy projects that do not come close to real professional developments. As such, recent graduates often fail to meet industry expectations when they first enter the workforce. In view of the gap between graduates’ skills and industry expectations, several institutions have resorted to integrating open-source software development as part of their programs. In this pilot study, we report on the results of the contributions of eleven students to the FIWARE open-source project as part of their final year project. Our findings suggest that both teachers and students have a positive perception towards contributing to the FIWARE open-source initiative and that students increased their knowledge of technologies valued by the industry. We also found that this kind of project requires an additional initial effort for the students as well as for the instructor to monitor their progress. Consequently, it is important that the instructors have previous experience in FIWARE, as many of the students need help during the process.

This article presents a comprehensive study of human physiology to determine the impact of body mass index (BMI) on human gait. The approach followed in this study consists of a mathematical model based on the centre of mass of the human body, the inertia of a person in motion and the human gait speed. Moreover, the study includes the representation of a building using graph theory and emulates the presence of a person inside the building when an emergency takes place. The optimal evacuation route is obtained using the breadth-first search (BFS) algorithm, and the evacuation time prediction is calculated using a Gaussian process model. Then, the risk of the building is quantified by using a non-sequential Monte Carlo simulation. The results open up a new horizon for developing a more realistic model for the assessment of civil safety.

In recent years, a new business paradigm has emerged which revolves around effectively extracting value from data. In this scope, providing a secure ecosystem for data sharing that ensures data governance and traceability is of paramount importance as it holds the potential to create new applications and services. Protecting data goes beyond restricting who can access what resource (covered by identity and Access Control): it becomes necessary to control how data are treated once accessed, which is known as data Usage Control. Data Usage Control provides a common and trustful security framework to guarantee the compliance with data governance rules and responsible use of organizations’ data by third-party entities, easing and ensuring secure data sharing in ecosystems such as Smart Cities and Industry 4.0. In this article, we present an implementation of a previously published architecture for enabling access and Usage Control in data-sharing ecosystems among multiple organizations using the FIWARE European open source platform. Additionally, we validate this implementation through a real use case in the food industry. We conclude that the proposed model, implemented using FIWARE components, provides a flexible and powerful architecture to manage Usage Control in data-sharing ecosystems.

The European electronic IDentification, Authentication and trust Services (eIDAS) regulation makes available a solution to ensure the cross-border mutual recognition of electronic IDentification (eID) mechanisms among Member States. However, the basic set of attributes currently provided by each country only contains citizens’ personal and legal attributes, preventing e-services to take full advantage of citizens’ domain-specific information, such as academic or medical data. In this article, we propose an extension of the eIDAS specification to support academic attributes as part of citizens’ profiles. In addition, we present an architecture to enable the connection of eIDAS nodes to national attribute providers to enrich citizens’ profiles with additional academic attributes. We have deployed the eIDAS extension in the specific case of the Spanish eIDAS infrastructure, and we have connected it to an attribute provider of the Technical University of Madrid (UPM). We have also improved a set of institutional services of that university by enabling the connection to eIDAS and enhancing the features offered to students based on their academic profiles retrieved from the eIDAS extended infrastructure. Finally, we have evaluated the resulting services thanks to real students from two different countries, concluding that the widespread adoption of the proposed solution in the academic services of European universities will greatly improve their quality and usability.

We are experiencing a new digital revolution in which data are becoming a key pillar for business and industry. Promoting data sharing, without compromising data sovereignty and traceability, is fundamental since it provides a heterogeneous ecosystem with the potential to enrich the variety of applications and services that take part in this digital revolution. In this scope, the use of secure and trusted platforms for sharing and processing personal and industrial data is crucial for the creation of a data market and a data economy. Protecting data goes beyond restricting who can access what resource (covered by identity and access control respectively): it becomes necessary to control how data are treated, which is known as data usage control. Data usage control provides a common and trustful security framework to guarantee the sovereignty and the responsible use of organizations’ data by third-party entities, easing and ensuring data sharing in ecosystems such as industry or smart cities. In this article, we present an architecture proposal for achieving access and usage control in shared data ecosystems among multiple organizations. The proposed architecture is based on the UCON (Usage Control) model and an extended XACML (eXtensible Access Control Markup Language) Reference Architecture, relying on key aspects of the IDS (International Data Spaces) Reference Architecture Model. Its modular design and technology-agnostic nature provide an integral solution while maintaining flexibility of implementation.

This paper describes a proof of concept of a Fast-Data architecture to generate early response alerts on unforeseen events. For achieving that, in this work is presented the implementation of a fully integrated system capable to handle and process streaming data in order to generate an alert response for each generated event. The deployment stated are composed by a simulated wireless sensor network for generating environmental values, a centralized Kafka server for data segmentation and a machine learning model deployed in a Spark cluster for generating the emergency alerts. Also, a simulation was conducted assuming that a fire had affected the simulated scenario in order to determine and evaluate the system's behavior. Finally, the classification model is presented as an early system alternative based on real-time processing and can be used in different areas of occupational safety.

In this paper, we present an analysis of the different database systems for storing the information gather by a wireless sensor network. In this work we present different test scenarios in order to evaluate the Fetch Time and the use of Mebibyte in Relational (MySQL, PostgreSQL) and No-SQL (MongoDB, Couch, Neo4J) databases. For achieving this goal, the database instances are deployed in Docker containers for providing the same deploy, host platform and, also present a performance analysis of the resources for each database. Moreover, we conduct a case of study focus in the storage of the asynchronous information collected by a WSN in a reactive evacuation system, this is information is handled by a Kafka cluster and Zookeeper topics. Finally the tests made in this work provide the information needed for making the correct elections of the database in this type of systems.

This paper states the development of a machine learning model capable of classifying whether a person who has cardiac problems is able to escape from a building if it is affected by an earthquake. The data used to train the model was obtained from a simulation which considered some parameters like earthquake magnitude, BMI, cardiovascular disease, person location within the building, and current evacuation routes. The result of this implementation presents a model able to determine whether a person inside the building could or could not go out of it depending on the parameters previously described, for achieving this goal the use of supervised learning algorithms like KNN and Decision Tree was needed. Also, the case study presents two scenarios, the first scenario presents an evaluation metric at normal walking speed and the second at fast walking speed for a person to escape from an affected building.

This paper introduces a conceptual review of Smart Cities to present a novel concept denominated Resilient Smart Cities (RSC). In this work, we provide a brief literature for IoT from the point of view of Smart Cities and its components: network, standards, services and requirements and how this digital ecosystem could be affected by unforeseen events. On the other hand, this article shows an overview of how the technology infrastructure and services can be affected by natural risks and consider as a solution the development of RSC. Moreover, a new architecture which includes the fundamental services that need to be preserved and prioritized in a Smart City has been considered for building a Resilient Smart City. Finally, a discussion about challenges and opportunities for the development of Smart Cities are mentioned.

In this paper, a distributed communication model is proposed to be implemented as part of a reactive evacuation management system. This implementation includes elements of wired and wireless network communications, which are used for sending and receiving information about the environment inside of a building. In this type of systems, where the sensor nodes of the network are continuously communicating, it presents a challenge for the classification and processing of the information. The aim behind this design, is using Zookeeper topics in order to allow Kafka server for transmitting the information of an alert state, this technique allow for the system to manage real time data transmission coming from the sensor nodes. Moreover, with this data, we can indicate an evacuation route through the reactive activation signaling. As this is an on-going study, we only illustrate our implementation with structural diagrams, but exclude the performance evaluation results in this paper.

In this paper, we explore the application of the Internet of things paradigm to the field of emergency management, proposing the combination of sensor networks and heterogeneous technologies actuators with an adaptive signaling system in order to provide a fast, reliable and safe adaptive path localization procedure The proposed system takes into account not only the search of the shortest evacuation route, but also the nature of the emergency, therefore avoiding or minimizing potential risk from, for example, stored goods or the, current, status of the emergency exits. Additionally A case study for a sport stadium is also presented to better illustrate the proposed solution.

In developing countries like Ecuador, the farmers don't have access to the technology needed to increase field production or reduce the water and energy waste typical of old farming methods. This paper presents the implementation of a low cost smart irrigation system that uses a modified wireless sensor network to provide the technology tools to those farmers in developing countries willing to change their method of production. Most of the system parts were designed, manufactured and integrated with low and local components minimizing the use of expensive imported parts in order to reduce the implementation cost and create new work opportunities. This project was focused in the substitution of components, hardware integration, protocol selection and modification, design for easy and non-specialized worker assembly.
