Abstract

The study and development of Internet of Things (IoT) applications, web and mobile, is on the increase. Applications, working with data obtained from different areas such as transportation, smart homes, health care, public services, industry and many others. Previous studies have focused on managing the obtained data. However, managing the heterogeneous resources that get that data is an area that demands more attention. This work addresses the management of resources in the Internet of Things. This is achieved by proposing a virtual-resource edge layer, which enables access and configuration to constrained physical resources. The architecture presented focuses on the use of virtual resources as a management concept and identifies different approaches in the performance evaluation on edge computing devices. Using the IoT protocol CoAP, virtual resources are exposed in the edge network. An evaluation of a Go CoAP virtual resource is presented.

5. Conclusions

This work abstracted the complexity of IoT resource access and configuratioin to an edge computing layer that is managed via CoAP protocol. Our virtual resource performed in an expected manner, responding to all requests no matter the concurrency level they faced. The virtual resource layer could interact between each compound components as easy as consuming a RESTfull service, in this case a CoAP RESTfull service. The proposed architecture constitutes an economic solution as the evaluation of the data is done in the IoT edge network and only useful information is transferred to the cloud. This is the first step in the construction of a complete edge-computing environment in which virtual resources are introduced as a recommended option for management in diversified IoT networks. Thus, we can fulfil the vision of the Internet of Things. As a future work, this research will introduce a tested with a large number of sensors and actuators to measure the overall application. Also, the work will include distributed virtual resources.
