Cloud-based Architecture for Deploying a Distributed Ambient Assisted Living Environment

Ambient Assisted Living (AAL) is starting to become the norm as more and more smart devices and sensors are installed in people’s homes. This is an important aspect in improving the quality of life, especially for the elderly and for people with disabilities.The solution presented in this paper approaches this paradigm in a large scale deployment context, as it proposes an AAL architecture on three layers (Edge, Dew, and Cloud), which is capable of handling high amount of sensor data in near realtime. Using a distributed system of rules engines, the system is able to take actions based on the acquired data. An important novel concept is the “new home deployment”, which facilitates the integration of the devices from a new installation site - the software setup of the new edge infrastructure is done by using a dedicated Cloud service. In order to showcase the practicality and efficiency of the architecture, this paper presents the intricacies of the employed services and service-interaction when deploying the solution on the OpenStack Cloud platform.
