Federated semantic nodes to scale search process in the IoT

The Internet of Things (IoT) refers to extending the Internet to heterogeneous components such as actuators, sensors or other smart devices. In this vision, the IoT foresees novel usage of such devices through applications enabling new device-device or device-people associations. Recent interest in providing digital extensions for these things has lead to billions of connected devices offering their services or data through different platforms, some of them wrapped with semantic descriptions to realize aforementioned associations through accurate search processes. However, the ubiquitous aspect of the IoT and the potential mobility of the devices that compose it, avoid adopting a centralized approach to search and manage these associations for scalability reasons. As devices composing the IoT are localized, we believe that designing a framework composed of geographically distributed and cooperating nodes with local reasoning capabilities is a much more scalable approach to realize the original IoT vision. We describe our vision by creating a federated network composed of such nodes that declare their location, process semantic descriptions of devices and share deduced associations with other peers that are selected based on their location nearness.
