The document presents ubox, a distributed resource management architecture for the Web of Things (WoT) aimed at facilitating both personal and shared use of sensor and actuator networks. It highlights the challenges in interconnecting WoT islands, discovering vendors, and encouraging data sharing, while proposing a simple and localized solution for users to create their own WoT environments. Furthermore, it describes the advantages of using ubox, such as efficient communication, asynchronous messaging, and the ability to register and manage devices through a unified API.

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 sandboxuBox@WoT 201112.06.201111

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 applicationsuBox@WoT 20112nd step:Large Scale Web-of-Things using uBox 12.06.201112
