Smart home is expected to offer various intelligent services by recognizing residents along with their life style and feeling
2、s. One of the key issues for realizing the smart home is how to detect the locations of residents. Currently, the research effort is focused on two approaches: terminal-based and non-terminal-based methods. The terminal -based method employs a type of device that should be carried by the resident wh
3、ile the non-terminal-based method requires no such device.There is a growing interest in smart home as a way to offer a convenient, comfortable, and safe residential environment. In general, the smart home aims to offer appropriate intelligent services to actively assist in the residents life such a
4、s housework, amusement, rest, and sleep. Hence, in order to enhance the residents convenience and safety, devices such as home appliances, multimedia appliances, and internet appliances should be connected via a home network system, as shown in Fig. 1, and they should be controlled or monitored remo
5、tely using a television (TV) or personal digital assistant (PDA).Especially, attention has been focused on location-based services as a way to offer high-quality intelligent services, while considering human factors such as pattern of living, health, and feelings of a resident. That is, if the smart
6、 home can recognize the residents pattern of living or health, then home appliances should be able to anticipate the residents needs and offer appropriate intelligent service more actively. For example, in a passive service environment, the resident controls the operation of the HVAC (heating, venti
7、lating, and air conditioning) system, while the smart home would control the temperature and humidity of a room according to the residents condition. Various indoor location-aware systems have been developed to recognize the residents location in the smart home or smart office. In general, indoor lo
8、cation-aware systems have been classified into three types according to the measurement technology: triangulation, scene analysis, and proximity methods 8. The triangulation method uses multiple distances from multiple known points. Examples include Active Badges, Active Bats, and Easy Living, which
9、 use infrared sensors, ultrasonic sensors, and vision sensors, respectively. The scene analysis method examines a view from a particular vantage point. Representative examples of the scene analysis method are MotionStar, which uses a DC magnetic tracker, and RADAR, which uses IEEE 802.11 wireless lo
10、cal area network (LAN). Finally, the proximity method measures nearness to a known set of points. An example of the proximity method is Smart Floor, which uses pressure sensors.Alternatively, indoor location-aware systems can be classified according to the need for a terminal that should be carried
11、by the resident. Terminal-based methods, such as Active Bats, do not recognize the residents location directly, but perceive the location of a device carried by the resident, such as an infrared transceiver or radio frequency identification (RFID) tag. Therefore, it is impossible to recognize the re
12、sidents location if he or she is not carrying the device. In contrast, non-terminal methods such as Easy Living and Smart Floor can find the residents location without such devices. However, Easy Living can be regarded to invade the residents privacy while the Smart Floor has difficulty with extendi
13、bility and maintenance. Home automation has come a long way from the manual timer hooked up to the living room light. Todays smart home automatically regulates heat, air and light, distributes audio and video around the house, controls access to your home and can even remind you to exercise! New tec
14、hnologies and product advances have made home technology systems more affordable than ever and have brought home systems integration into the mainstream. According to a study done in 2004 by the National Association of Home Builders Research Center and the Consumer Electronics Association, nearly ha
15、lf of all new homes being built in the U.S. are now using structured copper smart wiring to enable the installation of new home technology systems. How it Works There are four main types of networks you can install in your home to support the available new technology. Each has its advantages and dis
16、advantages depending on whether you are wiring a new home or upgrading an existing home. Structured wiring involves running specialized high performance cabling throughout your home. It provides a highly reliable and secure network that distributes data signals for phones, computers, TVs and audio components. Its ideal for new construction but not
