  Abstract

OpenADR protocol was developed to provide efficient use of energy and intelligent demand resource management services in a smart grid environment. The OpenADR demand response protocol based on HTTP/XML is difficult to use in lightweight devices with limited environments in homes and buildings because of the high overhead of data traffic. Recently, in the smart home energy IoT environment, a lightweight energy demand response protocol for ultra-lightweight devices is required. In this paper, we propose and evaluate a lightweight OpenADR 2.0b protocol based MQTT.　First, we implement the proposed protocol, and validate the compatibility with the existing HTTP/XML based OpenADR protocol through the testbed. Next, we analyze a push-based real-time event delivery mechanism using the publish/subscribe feature of MQTT through the experimental evaluation. From experiment results, we validate that the proposed MQTT based OpenADR protocol not only reduced by 1/3 in terms of data traffic, but also supported a response time within 0.01 seconds regardless of the number of VENs and polling intervals in real-time event delivery.
