Notification Oriented Paradigm Applied to Ambient Assisted Living Tool

Abstract

The rising in life expectancy is reflected in an increase in the elderly population and numerous actions become necessary to ensure the elderly a proper quality of life and independence in performing daily tasks. One of the applications of the Internet of Things technology (IoT) is the creation of smart environments with interactive devices allowing integration between the physical environment and the individual. A viable application of intelligent environments is the Ambient Assisted Living (AAL), which can enable elderly and people with some kind of limitations be assisted in their daily routine, independently and safely. In this context, in order to provide support technology, this research aims to evaluate the adhesion of Notification Oriented Paradigm (NOP) to IoT. NOP provides means for the development of robust systems, distributed, consistent, and rule-based systems for smart environments. Thus, to verify this adherence, it was created an application where is possible to manage rules and sensors dynamically and in real time, besides to enable notifications between sensors connected in different environments. This application can run on a microcomputer Raspberry Pi that simulates the rules and sensors in a virtual environment, acting as a simulator. The result of the simulation was evaluated by measuring the execution time of a set of rules notified among different environments. The results achieved for execution time, in the range of milliseconds, are sufficient for the demands required by systems in real scenarios, thus demonstrating the effectiveness of the intelligent systems developed by means of NOP.
