Ψ is an information ori- ented architecture built for the Future Internet using the so-called publish/subscribe paradigm. We advocate that by bringing information in the center of our solution as well as by applying Ψ’s particular security features we can achieve seamless information morphing and effective access control policies Categories and Subject Descriptors J.3 [Life and Medical Sciences]: Medical information sys- tems; H.m [Information Systems]: Miscellaneous General Terms Design, Experimentation, Standardization, Theory Keywords Content adaptation, Context awareness, Assistive informa- tion delivery, Future Internet 1. INTRODUCTION The introduction of pervasive healthcare paradigm has en- abled the awareness towards the elderly and the need for constant medical supervision of chronic patients or habitants at remote, isolated and underserved locations. In this con- text, advanced electronic healthcare services that were once available at big hospitals, are now required to be made avail- able through a network anytime, anyplace and to anyone.

The word “assistive” may also be used in a general way, including not only assisting per- sons with obvious health problems, but also empowering any human to improve the quality of life by enhancing sensing and computer based support at all levels. Thus the type of information that is exchanged in assistive environments is characterized by diversity and thus tools are needed for content adaptation. In such an environment, the notion of Future Internet and the new concepts/architectures that brings with, such as distributed and ad-hoc networking, cloud computing and elasticity in resources, Internet of Things and many oth- ers, can fit perfectly, enabling the development of advanced assistive applications. In this work we discuss the appli- cation of Future Internet technologies and architectures in assistive environments focusing on advanced networking and context awareness issues. We are particularly focused on a clean slate information oriented architecture; the Ψ archi- tecture. Ψ is a Future Internet architecture which utilizes information as its building block. It is based on the so-called publish/subscribe paradigm and it is designed to support effective and flexibly information governance and dissemi- nation. Information centric architectures appear to be ideal for pervasive healthcare environments as they achieve effec- tive information collection, provision, processing and gover- nance [11]. The rest of the paper is structures as follows: Section 2 presents the adaptation and context awareness requirements in assistive environments, while Section 3 summarizes the Future Internet technologies that can be exploited. Section 4 describes a proposed Future Internet architecture that cre- ates an assistive environment and Section 5 presents future work and concludes the paper. 2. INFORMATION DELIVERY AND CON- TEXT AWARENESS IN ASSISTIVE EN- VIRONMENTS The success of an assistive environment relies on the proper, accurate and on time delivery of information and data exchange between the involved individuals (users and operators). The latter however in addition to the complexity
