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.
