Abstract

Location tracking system represents position by searching objects and humans. In this paper I would like to write about RF chip support Zigbee which is called CC2420. In simulated network circumstance, we can get the information about mobile-node by sending it to sink-node. Position finding is in error by 3m at outdoor environment. The error scale is acceptable within easy range of naked eyes. It can be overcome by using GPS information and Google maps with the wireless networking background.

위치추정 서비스는 사물이나 사람의 위치를 추정하여 표현하는 것으로, 본 논문에서는 Zigbee를 지원하는 RF칩인 CC2420칩셋을 통한 네트워크 환경을 실외에 구축하고, 이동노드를 이용하여 GPS에서 얻어진 이동노드에 대 한 위치정보를 수신한다. 이동노드의 위치정보는 구축된 네트워크 환경에서 싱크노드에 전달함으로서 실시간으로 위치를 추정할수 있게 되며 실외환경에서 위치추정 오차는 3m 내에서 나타났으며 이는 육안으로 쉽게 판별가능한 범위이고 Google Maps을 이용하여 위치를 표현해 내었다.
