We have been studying Cloud HNS, which is a new type of home network system using the cloud. In this paper, we consider value-added services that can be provided by introducing a smart TV as an appliance of Cloud HNS. First, we discuss requirements, role and benefits of a smart TV in the integration with Cloud HNS. Then, we propose concrete scenarios of value-added services achieved by the integration.
In this paper, a household electric appliance remote controller operated without touching it is proposed. A prototype was prepared in order to evaluate the effectiveness of the proposed method.
The growth of the research and development on IoT (Internet of Things) devices, such as smart appliances, sensors, and network robots is significant, and there is increasing possibility of smart operation using such devices. In order to take full advantage of IoT devices, this paper proposes the multiagent-based cooperation infrastructure. As the core functionalities of the infrastructure, we propose...
To improve response time of time-sensitive application in a network using low speed communication link, implementation design of a middleware bundle adjusting bandwidth between applications is proposed and performance of the design is experimentally evaluated. The experiment shows that worst case delay of a high-priority packet is reduced from 4230 ms to 218 ms.
We have been studying log contexts using large-scale house log collected in home network system (HNS). A log context is defined with both the current and past situations of a house, where the current situation is characterized by the current status of an appliance (or a sensor), while the past situations are derived from the house log. In this paper, we propose context-aware services for smart TVs...
The paper proposed an optimal household load scheduling framework for home energy management systems to minimize the electricity bill and maximize users' comfort. The framework considers not only renewable energy and demand response requirement but also characteristics of home appliances and comfort level. Simulation results demonstrates its effectiveness.
Many standardization activities have been done for controlling and managing home networks and appliances during past ten years. Such activities include UPnP/DLNA, ECHONET and Continua Health Alliance and so on. However, there is no compatibility among those standards. To solve those problems, we have developed overlay networking protocols and device metadata technologies as a solution for controlling...
In this study, we propose an algorithm that enables home appliances (air conditioners) and lighting fixtures to estimate real-time occupant metabolic rate based on their heart rate and provide better thermal conditions for occupants in smart home environment. Occupant metabolic rate refers to the heat production of occupants, and smart home appliances can use this data to control environment factors,...
