A Proposed Framework for Context-Aware Semantic Service Provisioning

Web-Hosted Internet of Things (IoT) applications are the next logical step in the recent endeavor by academia and industry to design and standardize new communication protocols for smart objects. Context Awareness is defined as the property of a system that employs context to provide related information or services to the user, where the relationship is based on the user's task. Therefore, context-aware service discovery can be defined as utilizing context information to discover the most relevant services for the user. Merging context-aware concepts with the IoT facilitates IoT system developments that depend on complex environments with many sensors and actuators, user, and their environment. The main objective of this study is to design an abstract framework for provisioning smart objects as a service based on context-aware concepts while considering constraints of bandwidth, scalability, and performance. The proposed framework building blocks include data acquisition and management service and data aggregation, and rules reasoning. The proposed framework is validated and evaluated by constructing an IoT network simulation and testing accessing the service in the traditional method and according to the proposed framework and comparing the results.
