Context-Aware IoT Systems using Real-Time Data Analytics

The tremendous growth of the Internet of Things (IoT) has induced the proliferation of millions of interconnected devices that constantly generate massive volumes of real, time heterogeneous data. The majority of usual IoT systems are not capable of handling such a huge amount of data efficiently and responding to changes in the environment and user requirements. This article proposes a novel context, aware IoT framework where real, time data analytics capability is exploited to provide the adaptation and intelligence features in decision, making. The framework under discussion accomplishes local data preprocessing through edge computing and advanced context inference in the cloud through analytics. It thus facilitates the timely and proper understanding of both user and environmental conditions. Four main aspects of the system operation are signal acquisition from sensors, situation definition, continuous data analysis, and automatic implementation of actions. Experimental tests showed that the new framework is able to make devices more responsive and at the same time it reduces the amount of calculations and data transfer. Also, it leads to a higher precision of the context, driven actions as compared to a standard IoT setup. The present findings show that introducing context, awareness to an IoT system while offering the latter real, time analytics infuses it with agility, robustness, and excellent performance. The method has been demonstrated to be applicable to various areas such as smart homes, healthcare monitoring, industrial automation, and smart cities where high operational efficiency and user satisfaction are achieved through timely, context, aware decisions.
