Abstract

Portable devices such as smartphones with built-in wireless LAN to the prevalence of anyone using. But the wireless Internet connection and positioning services are limited to high-quality wireless service, they may not be available. Thus, wireless LAN infrared sensor in the same way as with angry alternative way wireless capabilities of the application automatically identify the location of the Sensor application as an alternative method is proposed. Thus, wireless LAN, such as infrared sensors and other alternzative methods of wireless features in a way where the application can recognize and automatically recognize the sensor application as an alternative method is proposed. Sensor is signals between wireless LAN and access points using the sensitivity, WLAN antenna with omni-directional signal output operation of the sensor is assumed to be recognize this by putting a direction to obtain through the proposed algorithm, Sensors such as photo-coupler without direct recognition sensor, wireless LAN and access points, the same function as the connection between the sensitivity to perform its function was to utilizing.

스마트폰과 같은 무선랜이 내장된 포터블 디바이스의 보급으로 누구나 무선랜을 사용하고 있다. 하지만 이러한 무선랜서비스는 인터넷의 접속과 위치 측위에 한정되어 있어 양질의 무선랜 서비스를 제공하는데는 한계가 있다. 따라서 무선랜의 센서화를 통해 적외선 센서방식과 같은 다른 대체방식으로 무선랜의 기능을 응용하여 자동적으로 위치를 인식할 수 있는 대체 인식 센서로서의 응용 방안을 제안하고자 한다. 센서화에는 무선랜과 엑세스포인트간의 신호감도를 사용하며, 무선랜 안테나 무지향성 신호출력으로의 조작을 가하고 이를 인식센서로 가정하여 방향을 인식하는 본 논문에서 제안한 알고리즘을 통하여 포토 커플러 등의 직접적인 센서가 없이도 인식센서와 같은 기능을 무선랜과 엑세스 포인트 간의 연결감도를 활용하여 그 기능을 수행할 수 있었다.
