Abstract: Ambient Assisted Living (AAL) systems main purpose is to improve the quality of life of special groups of people, including the elderly and people with physical disabilities. Driven by the critical ongoing changes in all modern, industrialized countries, there is a huge interest in IT-based equipment and services these days, to facilitate daily tasks and extend the independency time for these groups. Thence, AAL systems can benefit from the huge advances of both intelligent systems and communication technologies as promising growing research fields. The implementation of such complicated yet vital system should be established on solid bases relying on a standard architecture to satisfy and respond to the needs of heterogeneous stakeholders. This article proposes a Service Oriented Architecture model for Ambient Assisted Living Platform as a Service based on Wireless Sensors Network, it starts by presenting a classification of ambient assisted living services. Secondly, it describes some user and environmental challenges that have an impact on the service qualities. The discussion of architectural trends for AAL systems is included, and the description of challenges in designing and implementing of an effective one. Finally, this paper introduces a new vision of prototypical AAL systems architecture.
