In this paper, we propose an Internet of Things (IoT) virtualization framework to support connected objects sensor event processing and reasoning by providing a semantic overlay of underlying IoT cloud. The framework uses the sensor-as-aservice notion to expose IoT cloud's connected objects functional aspects in the form of web services. The framework uses(More)
The future Internet will embrace the intelligence of Web 3.0 and the omnipres-ence of every day connected objects. The later was envisioned as the Internet of Things. Security and interoperability concerns are hindering the service innovations using the Inter-net of Things. This paper addresses secure access provision to Internet of Things-enabled services(More)
This paper proposes a semantic enhanced service proxy framework for internet-of-things cloud. The framework exposes IoT cloud's smart objects as services by virtue of service orientation and virtualization. The framework uses an adapter oriented approach to address the issue of connectivity with different types of smart objects. We employ a query based(More)
—The Internet of things (IoT) is a network of smart objects that bridges the gap between the physical and the digital world. The prevalence of IoT leads towards a new digital ecosystem for building novel applications and services. However, heterogeneity in devices, technologies and standards are causing to impede the widespread adoption of IoT. Advances in(More)
This paper proposes a virtualized Internet of Services (IoS) space framework for connected objects. The framework allows to expose the connected objects sensor capabilities, functionalities and data as virtual sensor services and advertise these services to social network sites in addition to service registries for the enablement of a connected people IoS(More)
This paper proposes a semantic enhance social-aware user profile to address the issues of capturing and modeling user information for personalized services and contents. We also identify design requirements for user-centric profile to enhance its applicability in different domains and usage scenarios. In addition, the paper also provides the refinement(More)
Web based social communities are one of the most widely used applications nowadays. Recently, privacy concerns within these communities have increased significantly. This paper proposes a framework which addresses these challenges by introducing a distributed social community mechanism and relation based content access management by exploiting Semantic Web(More)
This paper addresses issues of service access, and policies to control access to these services. It introduces the mobile phone as a service aggregator and control centre for sensor networks. Semantic policies are used to extend the encryption-based radio link protection by an application layer protection. Two scenarios are introduced, covering home access(More)
Policies are familiar approach to preserve security and privacy of the Web contents and services. This paper is going to address the policy based constrained access to the home contents and services but in the context of distributed but connected devices. A community concept equipped with trust metric is introduced to facilitate such restricted access. The(More)
