Applying CoAP for real-time device control over public networks

Existing researches use CoAP for Internet of Things application, but the process of expanding the service scale is complicated or the researches are not suitable for the national network service. To solve this problem in this paper, we propose a method to apply CoAP for application to control device remotely. Through this, It possible to exchange data using CoAP without setting up a network in a nationwide network or large network. We apply CoAP to the proposed web-based remote control platform and check performance of the platform.
