Nowadays, the Portuguese population is aging at a fast pace. The situation is more severe in the interior regions of the country, where the rural areas have few people and have been constantly losing population; these are mostly elderly who, in some cases, live socially isolated. They are also often deprived of some types of social, health and technological services. One of the current challenges with respect to the elderly is that of improving the quality of life for those who still have some autonomy and live in their own residences so that they may continue living autonomously, while receiving the assistance of some exterior monitoring and supporting services. The Internet of Things (IoT) paradigm demonstrates great potential for creating technological solutions in this area as it aims to seamlessly integrate information technology with the daily lives of people. In this context, it is necessary to develop services that monitor the activity and health of the elderly in real time and alert caregivers or other family members in the case of an unusual event or behaviour. It is crucial that the technological system is able to collect data in a nonintrusive manner and without requiring much interaction with the elderly. Smartband devices are very good candidates for this purpose and, therefore, this work proposes assessing the level of acceptance of the usage of a smartbands by senior users in their daily activities. By using the definition of an architecture and the development of a prototype, it was possible to test the level of acceptance of smartbands by a sample of the elderly population—with surprising results from both the elderly and the caregivers—which constitutes an important contribution to the research field of Ambient Assisted Living (AAL). The evaluation showed that most users did not feel that the smartband was intrusive to their daily tasks and even considered using it in the future, while caregivers considered that the platform was very intuitive.

The world population growth is increasing the demand for food production. Furthermore, the reduction of the workforce in rural areas and the increase in production costs are challenges for food production nowadays. Smart farming is a farm management concept that may use Internet of Things (IoT) to overcome the current challenges of food production. This work uses the preferred reporting items for systematic reviews (PRISMA) methodology to systematically review the existing literature on smart farming with IoT. The review aims to identify the main devices, platforms, network protocols, processing data technologies and the applicability of smart farming with IoT to agriculture. The review shows an evolution in the way data is processed in recent years. Traditional approaches mostly used data in a reactive manner. In more recent approaches, however, new technological developments allowed the use of data to prevent crop problems and to improve the accuracy of crop diagnosis.

A body area network (BAN) comprises a set of devices that sense their surroundings, activate and communicate with each other when an event is detected in its environment. Although BAN technology was developed more than 20 years ago, in recent years, its popularity has greatly increased. The reason is the availability of smaller and more powerful devices, more efficient communication protocols and improved duration of portable batteries. BANs are applied in many fields, healthcare being one of the most important through gathering information about patients and their surroundings. A continuous stream of information may help physicians with making well-informed decisions about a patient’s treatment. Based on recent literature, the authors review BAN architectures, network topologies, energy sources, sensor types, applications, as well as their main challenges. In addition, the paper focuses on the principal requirements of safety, security, and sustainability. In addition, future research and improvements are discussed.

The number of users of the parking lots from the campus of the Polytechnic of Leiria, a higher education institution in Portugal, has been increasing each year. It is becoming a major concern to the organization to address the high demand for a free parking spot on campus. In order to ease this problem, this paper proposes the design of a smart parking system that can help users to easily find a free parking spot, using an integrated system that includes sensors and a mobile application. The system is based on the information about the occupation status of parking lots generated by parking sensors. This information is available in the mobile application that consumes a REST webservice and is presented to end-users, thus contributing to the decrease of time wasted on the quest of finding a free spot. The software architecture consists on a set of decoupled modules that compute and share the information generated by sensors. This architectural approach is noteworthy because it maximizes the system scalability and responsiveness to change. It allows the system to expand with the integration of new applications and perform updates on the existing ones, without an overall impact on the operations of the other system modules.

Ambient Intelligence promises to transform current spaces into electronic environments that will be responsive, assistive and sensitive to human presence and where all happens beyond user perception. Current computing interfaces, such as keyboards, mice, etc. will be removed at all or replaced by human ways of interaction like voice, gesture, emotions, etc. In order to materialize this new way of interaction between computing and people, we proposed a virtual butler able to make the link between ambient intelligence in general or smart spaces in particular and people. In fact, this is our second attempt to achieve that. Although tailored for smart homes, this virtual butler could be applied to other types of smart spaces and environments, such as shopping malls, airports, industry, etc. The developed virtual butler is able to interact with users by voice and it is sensitive to user location (and other context information).

The emergence both of World Wide Web and distributed systems solutions allowed many communication paradigms to appear, being the client-server the most common today. Here, we present an agent-based platform for the mobile agents computing paradigm. The platform components have been designed to allow the development, execution, tracking and the ability to move JavaScript mobile agents through the local network and Internet. All components are based on the JavaScript programming language in order to reach desktop and mobile operating systems, such as Android and iOS. This initiative arose as a way of dealing with problems raised by the considerable amount of existing Java based mobile agents platforms, which force the installation of the Java Virtual Machine on the devices, making complicated their execution in operating systems like macOS and others non-Java friendly operating systems, including mobile ones.

The evolution of technology in interconnection solutions such as Networks or the Internet, have allowed many communication architectures to be born and a varied interconnectivity. Here, we present a project that relies on the mobile agent computing paradigm. A middleware using the JavaScript language that allows the execution and ability to move mobile agents through the local network and Internet. This initiative arose as a way of dealing with problems raised by the considerable amount of existing Java based mobile agents middleware, which force the installation of the Java Virtual Machine in the devices, making complicated its execution in operating systems like macOS, iOS and others non-java friendly O.S. Our middleware works steadily in all operating systems, requiring only the installation of node.js. For mobile platforms the middleware is developed using React-native that allows it to run on mobile operating systems such as Android and iOS.

Wireless Body Area Networks (WBANs) supporting healthcare applications are in early development stage but offer valuable contributions at monitoring, diagnostic, or therapeutic levels. They cover real-time medical information gathering obtained from different sensors with secure data communication and low power consumption. As a consequence of the increasing interest in the application of this type of networks, several articles dealing with different aspects of such systems have been published recently. In this paper, we compile and compare technologies and protocols published in the most recent researches, seeking WBAN issues for medical monitoring purposes to select the most useful solutions for this area of networking. The most important features under consideration in our analysis include wireless communication protocols, frequency bands, data bandwidth, transmission distance, encryption, authentication methods, power consumption, and mobility. Our study demonstrates that some characteristics of surveyed protocols are very useful to medical appliances and patients in a WBAN domain.

With the increased improvements in healthcare, life expectancy has also increased. This has led to aging of the world's population. Families often have busy lives and do not have the time to give the elderly the support they need, taking these attending more and more households. The households are responsible for the medication, delegating greater responsibilities to employees. This leads to exist a huge responsibility for the health of elderly by part of the homes that host them. The homes that receive the elderly are responsible for the medication of them, delegating big responsibilities to the employees of the institution. They as human beings could make mistakes, may have negligence in giving the medication or even do not give it to them. Even more of them have less financial capabilities due by the country economic situation and often they have to let the medication for surviving. The Unidose Platform for Homes (UPH) come as a solution to counter and resolve this problems. It is possible to use the Unidose system which allows the medication sale by unit become more economical and also doing the prevention of taking the medication for not allowing negligence or shortages of takes. With the utilization of the platform the elderly lives and employees of the homes will stay much calmer, with less preoccupations improving their quality of life.

Wireless Sensor Networks, in particular Wireless Body Area Networks, is a technology suggested by the research community as allowing elderly people, or people with some kind of disability, to live in a safer, responsive and comfortable environment while at their homes. One of the most active threats to the autonomous life of blind people is the quantity and variety of obstacles they face while moving, whether they are obstacles in the footpath or obstacles coming out from the walls of buildings. Hence, it is necessary to develop a solution that helps or assists blind people while moving either in indoor or outdoor scenarios, simultaneously allowing the use of the use of white cane or the Seeing Eye dog. In this article, the authors propose the use of an ultra-sound based body area network for obstacle detection and warning as a complementary and effective solution for aiding blind people when moving from place to place. According to the cost estimates of the solution and to the negligible setup time, this could be a real effective complementary solution for blind people.

Ambient Intelligence promises to transform current spaces into electronic environments that are responsive, assistive and sensitive to human presence. Those electronic environments will be fully populated with dozens, hundreds or even thousands of connected devices that share information and thus become intelligent. That massive wave of electronic devices will also invade everyday objects, turning them into smart entities, keeping their native features and characteristics while seamlessly promoting them to a new class of thinking and reasoning everyday objects. Although there are strong expectations that most of the users’ needs can be fulfilled without their intervention, there are still situations where interaction is required. This paper presents work being done in the field of human-computer interaction, focusing on smart home environments, while being a part of a larger project called Aging Inside a Smart Home. This initiative arose as a way to deal with a large scourge of our country, where lots of elderly persons live alone in their homes, often with limited or no physical mobility. The project relies on the mobile agent computing paradigm in order to create a Virtual Butler that provides the interface between the elderly and the smart home infrastructure. The Virtual Butler is receptive to user questions, answering them according to the context and knowledge of the AISH. It is also capable of interacting with the user whenever it senses that something has gone wrong, notifying next of kin and/or medical services, etc. The Virtual Butler is aware of the user location and moves to the computing device which is closest to the user, in order to be always present. Its avatar can also run in handheld devices keeping its main functionality in order to track user when s/he goes out. According to the evaluation carried out, the Virtual Butler is assessed as a very interesting and loved digital friend, filling the gap between the user and the smart home. The evaluation also showed that the Virtual Butler concept can be easily ported to other types of possible smart and assistive environments like airports, hospitals, shopping malls, offices, etc.

PH is a vital physiological parameter that can be used for disease diagnosis and treatment as well as in monitoring other biological processes. Metal/metal oxide based pH sensors have several advantages regarding their reliability, miniaturization, and cost-effectiveness, which are critical characteristics for in vivo applications. In this work, WO3 nanoparticles were electrodeposited on flexible substrates over metal electrodes with a sensing area of 1 mm2. These sensors show a sensitivity of −56.7 ± 1.3 mV/pH, in a wide pH range of 9 to 5. A proof of concept is also demonstrated using a flexible reference electrode in solid electrolyte with a curved surface. A good balance between the performance parameters (sensitivity), the production costs, and simplicity of the sensors was accomplished, as required for wearable biomedical devices.

We are assisting to the fastest grow of senior population ever and that tendency has brought several challenges for governments, families and for the elderly. The society was not prepared for that. On the one hand, there are many elderly who live alone in the cities and, on the other hand, active people is moving to the cities looking for a better life while leaving behind the villages where they born and grow and the older family members. On the other side, everyone is expecting the aid of technology in order to solve or at least minimize this problem. This paper present a video-calling service targeted for elderly social and technological exclusion and promoting socialization while using recent technology embedded into well-known electronic devices like TVs. The evaluation of results showed that when assisted technology is encapsulated into everyday objects, older people can use it seamlessly, without any learning curve.

The technological advances in medical sensors, low-power microelectronics and miniaturization, wireless communications and networks have enabled the appearance of a new generation of wireless sensor networks: the so-called wireless body area networks (WBAN). These networks can be used for continuous monitoring of vital parameters, movement, and the surrounding environment. The data gathered by these networks contributes to improve users’ quality of life and allows the creation of a knowledge database by using learning techniques, useful to infer abnormal behaviour. In this paper we present a wireless body area network architecture to recognize human movement, identify human postures and detect harmful activities in order to prevent risk situations. The WBAN was created using tiny, cheap and low-power nodes with inertial and physiological sensors, strategically placed on the human body. Doing so, in an as ubiquitous as possible way, ensures that its impact on the users’ daily actions is minimum. The information collected by these sensors is transmitted to a central server capable of analysing and processing their data. The proposed system creates movement profiles based on the data sent by the WBAN’s nodes, and is able to detect in real time any abnormal movement and allows for a monitored rehabilitation of the user.

In the past, wireless sensor networks emerged and so did some state-of-the-art applications that ran above them. Most of those applications followed the centralized model and were mainly focused on environmental data gathering, where sensor nodes sensed data from the environment to be sent to an external data server for later processing. Further research took wireless sensor networks to new application areas and, today, this technology gained the ubiquitous status. However, the use of wireless sensor networks is still reserved to experts, mainly due to the huge gap between user applications and the network. This fact has led us to successfully develop a new software stack, capable of running in any sensor node even in the most resource-constrained ones. The new software stack offers a truly service-oriented approach to design and implement applications and follows a widely accepted programming language and programming paradigm.

Ad-hoc networks present new challenges due to its mobility, lack of infrastructure and resource limited devices. This means that service discovery (and usage) protocols targeted for traditional networks are not suitable for ad-hoc networks because they usually rely on the fixed and high availability characteristics of nodes to run important services. Ad-hoc networks need service discovery protocols compliant with its mobility and changing topology. In this paper we present a practical solution capable of provide automatic service discovery and usage over ad-hoc networks of resource poor sensor nodes. The solution was not developed from the ground-up. Instead, it was based on a (successfully) solution for traditional networks but then modified to address ad-hoc networks while keeping it original semantics.

Wireless Sensor networks (WSNs) have been referred to as one part of the background infrastructure required to achieve ubiquitous computing, where smart spaces are included. For instance, WSNs could be especially useful to compute the user context or even `context' of mobile resources in general. To serve this purpose, wireless sensor network must expose some sort of service discovery and usage capability and be compatible with the nowadays ubiquitous technologies. In this paper we present a practical approach to bring WSNs, specially the ones built from resource poor sensor nodes, to participate into smart environments as ubiquitous devices. The approach addresses device heterogeneity, uses the state of the art and ubiquitous TCP/IP communication stack, is service driven and do not rely in any external resource rich device. As a result, we successfully created a Java based service discovery and usage protocol that is compliant with ad-hoc networks and resource constrained devices and a framework capable of produce the source and binary code ready to run on both resource constrained sensor nodes and PCs.
