홈네트워크는 1980년대 Home Automation에서 출발한 개념으로서 가전기기의 자동 및 원격제어, 가정에 쓰이는 에너지(전기ㆍ가스 등)의 효율적 이용, 각종 방범 등을 목적으로 시작하였다. 그러나 Home Automation은 많은 비용을 수반하였고 가전장비와의 통신에 제한이 있었기 때문에 일반인들 속으로 파고들지는 못하였다. (중략)

This paper presents new type remote home automation that can control and manage hi-directionally and efficiently home appliances and home security systems in home through Internet. The system is used virtual reality technology to construct very easy user interface and used Internet as network for remote control. Here, the user interface is 3D GUI which gives user feeling to be at his home on web-browser, and also shows him present state of control objects at home. This system has been implemented on the basis of Java and VRML. In this paper we propose the internet-based remote control system, and show usefulness of the suggested system by applying to home automation system.

Home automation networks are good environments for merging sensor networks and consumer electronics technologies. It is very important to reduce the energy consumption of each sensor node because sensor nodes operate with limited power based on a battery that cannot be easily replaced. One of the primary mechanisms for achieving low energy operation in energy-constrained wireless sensor networks is the duty-cycle operation, but this operation has several problems. For example, unnecessary energy consumption occurs during synchronization between transmission schedules and sleep schedules. In addition, a low duty-cycle usually causes more performance degradation, if the network becomes congested. Therefore, an appropriate control scheme is required to solve these problems. In this paper, we propose UDC (Unsynchronized Duty-cycle Control), which prevents energy waste caused by unnecessary preamble transmission and avoids congestion using duty-cycle adjustment. In addition, the scheme adjusts the starting point of the duty-cycle in order to reduce sleep delay. Our simulation results show that UDC improves the reliability and energy efficiency while reducing the end-to-end delay of the unsynchronized duty-cycled MAC (Media Access Control) protocol in sensor-based home automation networks.

Home automation technology combines various devices in home organically with each other to ensure the convenience and improved safety of the home life refers to a technique for improving the human living. Because of the technology needed to make this house before you can act as awareness of your thoughts. In this paper, we implement the system model, such as data collection using a sensor network, and take advantage of the idea that the data itself to the home, and an introduction to the method.

In this paper, we design a ubiquitous home automation system for Korean domestic 33-Pyung Apartment based on USN environment. The core of this home automation system is to give Home the 'Intelligence' so that the house can analyze and memorize the occurrences and react spontaneously on the user requirements by means of the World Model, USN, and LBS etc. Ultimately, the resident of this intelligent home might access all of these ubiquitous environments without any feelings about the equipments and peripherals. The methods of user identification, image recognition, and the ultrasonic sensors locations have been applied to Korean domestic 35-Pyung Apartment, but they will be easily generalized to be an extended model because of the flexibility of the World Model. which are confirmed by the imaginary scenario presented at the end of the main left.

Smart Home or Home Network technology is one that continuously creates added value, making a better life. This paper designed and developed a smart home control system using smart phone. This proposed smart home system consists of home server control system, remote smart application system and home node structure. Home node structure, in detail, is composed of intrusion detection, gas leakage or gas valve control, door lock, automatic curtain, ventilation control and On/Off control modules and these modules are controlled at home server. Home server makes it easy to control home automatic control system anytime, anywhere as it provides remote interface that enables control via smartphone and user interface in itself.

This paper deals with the design and implementation of wireless sensor network protocol for smart power outlet system capable of fire detection, power monitoring, standby power cutoff, and home automation. The proposed protocol integrates both the CSMA and the TDMA protocols for low power consumption and good scalability. A prototype smart power outlet system employing the proposed protocol and a simple home automation network including the power outlet system have been implemented for evaluating the feasibility of the proposed protocol The result shows that the proposed protocol allows the power outlet system to be scalable with high power efficiency.

This paper proposes a new concept's IDSFHA(Intelligent Digital Switchgear For Home Automation) which can obtain the safety, the reliability and the easy to correspond to the request of the general electric customer or electric power company under the ubiquitous-based home automation environments The IDSFHA is designed by analyzing their requirement functions, a 32-bit micro processor is adopted as main controller to support efficiently the designed functions. The single phase power IC(ADE7753) is utilized to collect the electric power information, and makes it possible to communicate as internet among the IDSFHA and their using the ethernet convertor. In the proposed IDSFHA, the several functions are implemented such as the earth leakage level display and waveform transmitting, the electric power using fee display, voltage management, load management and load control function. Finally, the prototype of the IDSFHA is made experimently based on the designed results.
