The ageing process involves several transformations within the human body, including a decline of the skeletal muscle tissue, described as sarcopenia, and a decrease in cognitive function. As the number of ageing people is increasing, the use of technology will help in the promotion of independent living. Sensors are commonly available in many devices and they can be used for the acquisition of physical and physiological parameters for pervasive monitoring of older adults. These devices include but are not limited to mobile devices such as smartphones and smartwatches. Currently, mobile devices include a wide variety of sensors such as accelerometers, gyroscopes, magnetometers, and GPS that can be used to design and develop enhanced sensor-based systems for independent living. Numerous researchers are developing cyber-physical systems using cost-effective microcontrollers and sensors. Furthermore, Internet of Things technologies can be applied to create wireless ecosystems of sensor nodes that can provide a continuous stream of data. These data can be transformed using machine learning methods for enhanced living environments.

Nevertheless, several challenges for the implementation of sensor-based systems for independent living of older adults still exist. These challenges include the price of the implementation and installation of these systems, the complexity of methods, efficient data transmission, and energy consumption. Moreover, it is necessary to ensure the best guidelines to ensure the privacy and security of the users.

This Special Issue is focused on the presentation of state-of-the-art, ongoing projects, conceptual definition of systems, developed projects, and all facets involving sensor-based networks, services, and applications for ambient assisted living. Several health-related problems can be monitored and minimized with the use of technological equipment. The main objective is to present the recent advances in the field and provide an overview of the common advantages and limitations of the systems available in the literature for enhanced living environments. These systems are crucial to enable continuous pervasive monitoring of older adults for enhanced living environments and well-being. Original research and review articles are welcome.
