In the Internet of Things1,2, the communication and resource management have been performed based on the technology in which the constrained network is implemented 6,7,8. Each vendor has made sure of developing its own encapsulated-compatible and propietary communication standards. Applications have been supported by those propietary standars to get reliable information in an efficient and secure manner from the constrained environment to the cloud 3,4,5. This has influenced users to adopt a certain technology in entire implementations to facilitate the duties of management (ITU-T M.3400). There has been some studies on facing IoT physical devices, but their main goal has been to facilitate the job of developers 10,11. Nowadays, there is not a solution to allow access to diversified IoT network resources to get their information. This causes limitations in fulfilling the vision of the Internet of Things9. This work extends that vision not only having interconnected heterogenous ”things”, but also getting information in real time about those ”things” that are working in the environment. The architecture put forward is focused on abstracting the complexity of access and configuration of heterogeneous constrained networks resources to the concept of virtual resources, offering a simplified management option. This work proposes the creation of virtual resources running in edge computing devices. Also, this study adopts the Constrained Application Protocol (CoAP) to communicate the virtual resources and the Go programming language to build them. This representation allows constrained components to be easily accessed from third parties. The direct communication with physical resources is broken up introducing virtual resource layers. The remainder of the paper is structured as follows. Section 2 presents the definition of our IoT resources. Section 3 explains the experimental setup. Section 4 presents the performance evaluation of our prototype and the paper concludes with a summary in section 5.
