An IoT Service Framework for Smart Home: Case Study on HEM

Nowadays, most of smart home applications are either ad hoc or close/monolithic. So it is critical to study novel software architecture/frameworks which are open, connecting multiple heterogonous devices and multiple networks, supporting multiple concurrent applications, enabling reliable data/command delivery among home gateway and cloud/smart phone, and easy to develop third party service business applications. To achieve the above demand, this paper proposes a service framework for smart home which well combines Lab of Things (HomeOS), MQTT and Azure cloud. To validate this service framework´s rationality and combine high energy consumption of the whole society, based on this service framework, we developed a smart home energy management service system, which includes two sub-systems, i.e. Home energy management application running on home gateway, and energy service system for multi-homes running on Azure cloud and operated by specialized 3rd party energy service provider.
