Virtualizing Sensor for the Enablement of Semantic-aware Internet of Things Ecosystem

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 embedded service oriented architecture (SOA) for resource-constrained devices make it possible to expose the functional aspects of smart objects in the form of IoT web services. However, these IoT services are highly susceptible against a number of security attacks due to both the open nature and resource limitation of smart objects. This paper proposes a framework to address the service virtualization and security issues in order to ease off the IoT services development. Our exploration shows that the vigilant amalgamation of e-SOA, virtualization, semantic web technologies, sensor technologies paves the way to address the connectivity, security and monitoring issues of IoT.
