The idea is to provide, in an integrated way, a set of smart and context-aware services that improve the quality of life and social integration of elderly. This paper shows the design of the platform from the lowest levels for sensing health parameters of elderly and their location, up to the highest level of smart assistance services. Furthermore, we describe a smart health services for detection of falls and assistance to elderly, as an example of application of our platform that we are already experimenting with.
