 Abstract
Recently, a communication protocol for connectivity between various sensors and actuators is issue the key technology in IoT(Internet of Things). IETF(Internet Engineering Task Force) CoAP(Constrained Application Protocol) protocol supports the communication between things like sensors and actuator nodes in a limited environment. Smart-phone will work for the data processing of the sensors and the management of IoT nodes at the next generation communication environment. In this paper, we design the connection for smart-phone and IoT node based using IETF CoAP protocol, and implement the middleware with the proposed data refinement on smart-phone. The middleware detects and eliminates a error data and duplicated data using the proposed data refinement. The proposed data refinement scheme supports to transfer a reliability information in the constrained environment.
