- Smart mobility: a surveyPublication . Faria, Ricardo; Brito, Lina; Baras, Karolina; Silva, JoséInternet of Things (IoT) describes a world where everyday objects are always connected to the Internet, allowing them to communicate and interact with each other. By connecting these everyday objects to the Internet and making them available everywhere at any time, IoT allows to remotely monitor, manage, and gather status information about them and their surrounding environment. IoT is a revolutionary concept that brought new experiences to everyday life and enabled Smart City initiatives all over the world. These initiatives are using a combination of technology paired with physical infrastructure and services, to improve people’s quality of life. One of the high priority domain to support the Smart City’s vision is the field of Smart Mobility. This paper reviews the current IoT approaches and concepts related to Smart Cities and Smart Mobility. In addition, it analyzes distinct features and numerous applications covering both Intelligent Transportation and Real Time Traffic Management Systems.
- Smart mobility: a mobile approachPublication . Faria, Ricardo; Brito, Lina; Baras, Karolina; Silva, JoséThe Internet of Things (IoT) is one of the key ingredients for the real ization of Smart Cities. IoT devices are essential components of the Smart Cities infrastructure, as they can provide information collected from the environment through sensors or allow other systems to reach out and act on the world through actuators. IoT data collection, however, is not limited to sensors and machines, but to data from social networks, and the web. Social networks have a huge im pact on the amount of data being produced daily, becoming an increasingly cen tral and important data source. The exploitation of these data sources, combined with the growing popularity of mobile devices, can lead to the development of better solutions to improve people’s quality of life. This paper discusses how to take advantage of the benefits of mobile devices and the vast range of information sources and services, such as traffic conditions, and narrow, closed or conditioned roads data. The proposed system uses a real-time collection, organization, and transmission of traffic and road conditions data to provide efficient and accurate information to drivers. With the purpose of supporting and improving traffic data collection and distribution, an Android application was developed to collect in formation about extraordinary events that take place in a city, providing warnings and alternative routes to drivers and helping them to improve their time manage ment. The developed solution also exploits the existing gaps in other applications, implementing a more specific solution for the Madeira Island traffic condition problems.
- Overview of context-sensitive technologies for well-beingPublication . Freitas, André; Brito, Lina; Baras, Karolina; Silva, JoséToday smart devices such as smartphones, smartwatches and activity trackers are widely available and accepted in most developed societies. These devices present a broad set of sensors capable of extracting detailed information about different situations of daily life, which, if used for good, have the potential to improve the quality of life not only for individuals but also for the society in general. One of the key areas where this type of information can help to improve the quality of life is in healthcare since it allows to monitor and infer the current level of well-being of the smart devices carriers. In this paper, some of the available literature about well-being sensing through context-aware data is reviewed. Also, the main types of mechanisms used in these studies are identified. These mechanisms are related to monitoring, generalization, inference, feedback, energy management and privacy. Furthermore, a description of the mechanisms used in each study is presented.
- Towards a novel optical access networks management solution: addressing general management complexityPublication . Gonçalves, Tiago; Baras, Karolina; Brito, LinaPast technological advances and an increasing need to communicate have led to the creation of the current telecommunications networks. A critical part of a telecommunications network is the access network, since it must bridge the clients with the services provided, ensuring an efficient connection between them. In the last few years, both governments and organizations from several countries have adopted large fiber optics implementations in their access networks, given its broadband capabilities. However, the structure of such networks can become very complex, forcing organizations to use means that allow them to efficiently manage such complexity. Several software solutions available on the market are capable of providing management features for these networks, but the complexity of these solutions can negatively affect management, making it lengthy and error-prone. In this paper, we describe the initial development of a software solution, consisting of a set of integrated tools that will make optical access networks management more efficient by addressing the complexity limitations of the current solutions. One of the tools, presented in this paper, was tested with a local ISP (Internet Service Provider) and showed to be capable of overcoming the limitations faced by the organization on managing their optical access network.
