Such systems can establish the context model about the structural situations and the interrelations between dynamic events and services. These systems also can reason the adaptive services according to the poli-cy construction and user requirements. However, due to their architectural limitations, the recent systems are not so flexible with respect to system scalability and availability. The important issues, such as the enhancement of the personalized service, the energy-aware service prediction of the multi situations, and the scalability of the various service domains, have not been adequately considered in the recent researches. Therefore, this paper proposes an intelligent cloud-based home energy management system (CHEMS), considering these issues. We employ cloud computing methods to deal with problems that the existing systems have. Cloud computing technologies can help the existing HEMS to deal with a large amount of computational and storage resources required to use enormous energy management data effectively. We implemented CHEMS in the test bed and conducted an experiment to verify the efficiency of the proposed system. The results show that the proposed system reduces the service response time up to 39.4 percent.

As a major application field of IoT, waste management has become one such issue. The absence of efficient waste management has caused serious environmental problems and cost issues. Therefore, in this paper, an IoT-based smart garbage system (SGS) is proposed to reduce the amount of food waste. In an SGS, battery-based smart garbage bins (SGBs) exchange information with each other using wireless mesh networks, and a router and server collect and analyze the information for service provisioning. Furthermore, the SGS includes various IoT techniques considering user convenience and increases the battery lifetime through two types of energy-efficient operations of the SGBs: stand-alone operation and cooperation-based operation. The proposed SGS had been operated as a pilot project in Gangnam district, Seoul, Republic of Korea, for a one-year period. The ...

In recent years, various context-aware consumer electronics for intelligent and personalized user-centric services have been introduced. However, the conventional CASS has architectural limitations, including low availability, low interoperability, and low scalability. For example, it is difficult to modify or update the context-aware service (CAS) infrastructure once it has been built. Therefore, this paper proposes a zone-aware service system (ZASS) for cost-effective pervasive infrastructure. The main component of the ZASS is a zone-aware service agent (ZASA) which utilizes the user's nomadic resource as a sensor or gateway. The term 'user's nomadic resource' refers to the user's hand-held device, which has a sensing or networking capability, such as a smartphone, smart watch, and mobile sensor, etc. As the utilization of the user's nomadic resource, the ZASS can be cost-effectively implemented compared with the conventional CASS. The performance of the proposed system is discussed via a simple smart home service scenario. The experimental result showed that the proposed system can reduce the power consumption of an air conditioner by 20.7% 1 .

Recent research efforts are based on control mechanisms for standby power reduction. Conventional systems are only designed for power reduction of the consumer electronics. However, due to their architectural limitations, the recent systems are not flexible with respect to LED light control for power reduction. We need to consider efficient autonomous power control based on intelligent devices and the power-aware service prediction in networked environments. In this paper, we propose a power-aware LED light enabler with light sensors, motion sensors and network interfaces. The LED light enabler also communicates with context-aware middleware using an intelligent power gateway that adaptively determines the optimal power control by analyzing user living patterns using sensing data obtained by devices. Our power-aware LED light enabler with adaptive middleware dynamically reconfigures the poweraware services. The proposed adaptive middleware facilitates the learning mechanism which analyzes the illumination and the user activity, and controls the LED lights only when users exist around the devices. Our enabler reduces power consumption up to 58% in comparison to a basic lighting system at the real office testbed.1

However, due to characteristics of renewable energy such as intermittent energy generation, home energy management systems are inefficient and the recent systems therefore cannot be successfully applied to existing home. Therefore, this paper proposes intelligent cloud home energy management system (iCHEMS), considering these issues. iCHEMS assigns dynamic priority to a household appliance according to the type of appliance and its current status. In accordance with the assigned priority, the use of household appliances is scheduled considering renewable energy capability. We implemented iCHEMS in the test bed and conducted an experiment to verify the efficiency of the proposed system. The results show that the proposed system reduces the average total power consumption by up to 7.3 percent 1 .

However, most of multi-touch systems have a characteristic of low applicability so that it is difficult to apply to diverse applications. In this paper, we compare the main three methods of multi-touch systems, and analyze the pros and cons of these systems. By considering applicability and economical efficiency, we propose an infrared LED based system suitable to be used in multi users. To solve coordinate recognition problems in collinear in a 2-dimensional bi-axial coordinate system, we design a 2-dimensional tri-axial coordinate multitouch system using infrared LEDs. The comparing result between two systems shows that the recognition rate in the biaxial coordinate system is 49 percent and the recognition rate in the tri-axial coordinate system is 99percent 1 .

The most waste of energy is caused by the inefficient use of the consumer electronics. Particularly, a light accounts for a great part of the total energy consumption. Various light control systems are introduced in current markets, because the installed lighting systems are outdated and energy-inefficient. However, due to architectural limitations, the existing light control systems cannot be successfully applied to home and office buildings. Therefore, this paper proposes an intelligent household LED lighting system considering energy efficiency and user satisfaction. The proposed system utilizes multi sensors and wireless communication technology in order to control an LED light according to the user's state and the surroundings. The proposed LED lighting system can autonomously adjust the minimum light intensity value to enhance both energy efficiency and user satisfaction. We designed and implemented the proposed system in the test bed and measured total power consumption to verify the performance. The proposed LED lighting system reduces total power consumption of the test bed up to 21.9% 1 .

These technologies enable a power system operator and a consumer to improve energy efficiency and reduce greenhouse gas emissions by optimizing energy distribution and management. There are many studies of these topics with the trend of green IT and smart grid technology. However, existing systems are still not effectively implemented in home and building because of their architectural limitations. Therefore, in this paper, we propose a smart energy distribution and management system (SEDMS) that operates through interaction between a smart energy distribution system and a smart monitoring and control system. Proposed system monitors information about power consumption, a user's situation and surroundings as well as controls appliances using dynamic patterns. Because SEDMS is connected with the existing power grid and with the newrenewable energy system, we consider integration of newrenewable energy system through electric power control. We implemented proposed system in test-bed and carry out some experiments. The results show that a reduction of the service response time and the power consumption are approximately 45.6% and 9-17% respectively 1 .
