Developed countries worldwide are facing a rapidly growing elderly population and a declining workforce, as a result of increased life expectancy and decreased birth rates. According to the United Nations, the elderly, defined as people over the age of 60, will make up 37% of the European population by 2050, from 20% in 2000. With ageing, probability increases of developing physical and cognitive impairments, requiring new and more effective ways to provide support and care. IoT technology may provide significant enhancement to quality of life for the elderly and, in general, people in need. Effective solutions for Ambient Assisted Living (AAL) require appropriate ICT algorithms, architectures and platforms, that cannot leave out of consideration the development of new and innovative approaches, particularly in the area of pervasive and mobile systems. The personal communication between elderly people, their environment, and relevant groups of care givers is an important aspect in AAL; such a need for a pervasive connectivity may leverage the IoT capabilities, to connect humans to smart objects, and put smart objects at the service of users’ needs. At the same time, the realm of Active and Assisted Living may provide a way to capitalize the vast amount of research and knowledge developed up to know in the manifold aspects and facets of IoT. This workshop aims at investigating the close relationship among IoT and AAL, to identify effective approaches towards an increased Quality of Life for the current and future ageing populations. Among the different technical issues that have to be considered when designing IoT solutions for AAL, some of them emerge as critical, i.e.: low power communication technologies and energy-saving design at different layers, and in a cross-layer approach; security and privacy issues, both at the single node/object level, and in a system/platform perspective; big data, analytics, and signal processing for AAL enabled by an IoT approach; cloud and mobile cloud architectures supporting AAL through IoT. IoTAAL will bring researchers from the IoT field and the AAL field together, to foster a better common understanding, to exchange visions and latest research results addressing IoT specialization for AAL, to discuss promising new technologies and to highlight open research challenges.
