에너지 IoT 환경에서 실시간 수요반응 서비스를 위한CoAP Observe 기반 Push Mechanism 설계 및 분석

초록

This paper studies on realtime Demand Response(DR) mechanism for improving energy efficiency in smart home and home appliance-based Energy Internet of Things(EIoT) environment while preserving quality of experience for energy producer and consumer. The objective of this paper is the design and implementation of real-time DR protocol using Constrained Application Protocol(CoAP) / JSON based Observe capability in order to provide real-time energy management of smart home and appliances in EIoT. At first, this paper studies on Open Automated Demand Response(OpenADR) mechanism and shows the necessary of real-time interactive demand response and energy management services in EIoT environment. Next, this paper designs OpenADR push mechanism using CoAP Observe capability. Finally, this paper implements and compares the push and pull mechanisms to verify the advantages of the proposed push mechanism in terms of performance and efficiency in real-time environment.
