에너지 IoT 환경을 위한 Multicast 방식의Lightweight 수요반응 프로토콜 제안 및 분석

초록

Open Automated Demand Response (OpenADR) has been developed as a standard protocol to provide intelligent demand response services for utility companies and demand response operators. In the residential space, demand response technology is being used to increase energy efficiency while increasing user satisfaction with the concept of intelligent energy consumption rather than simple power saving. However, demand response services to residential areas are expanding. In the residential space, many users and IoT devices are connected in a point-to-multipoint manner. Therefore, existing OpenADR 2.0b messaging protocol, HTTP / XML based data modeling and unicast message transmission are not appropriate. In this paper, we propose a lightweight demand response protocol by using Broker which is based on multicast message transmission method in Smart Energy IoT environment, implement multicast based demand response Message Queuing Telemetry Transport (MQTT) protocol and compare the performance to that of OpenADR protocol.
