Although there are many smart devices and networked embedded object applications usingWorld WideWeb technologies, it is still a big step to go towards a true Web of Things. It is e.g. difficult to build ubiquitous WoT applications that work in and accross multiple environments. Approaches which aggregate WoT ressources by centralizing all the resource information, have problems: total dependency on external infrasture, lack of private WoT management, inflexible communication patterns and limited dynamic ressource discovery and mapping. To solve these problems, we propose uBox, a localWoT platform which can be a stand-alone server to make your WoT environment, with interfaces to connect the other local WoT platforms. This way, which we call uBoXing, we can create World Wide WoT platform with a distributed architecture. This paper describes the concept of a distributed resource management architecture, and how we implement the concept into software. Also, we will discuss the platform with the example application in SmartTecO environment.

11. 1st step:Local Web-of-Things using uBox In home, office or school, users should place uBox and create their own Web-of-Things by registering http-based devices. This enables users to control variety of devices with an unified API. People create applications privately in a sandbox uBox@WoT 2011 12.06.2011 11

12. uBoxes are interconnected to other uBoxes over P2P network. Users can connect not only their local devices but also global devices as well from their uBox as an entry point. People share sensors and applications uBox@WoT 2011 2nd step:Large Scale Web-of-Things using uBox 12.06.2011 12
