초록

모바일 센서 네트워크(Mobile Sensor Network)의 노드(Node)인 모바일 센서 차량(Mobile Sensor Vehicles)들은 특정 지역에 관해 획득한 정보를 서로 교환하고 통합하는 과정을 거쳐 자신의 위치를 파악하게 되는데 이를 지역화(localization)라 한다. 이때 모바일 센서 차량은 탑재된 각종 센서를 이용하여 자신의 위치 정보를 파악한다. 본 연구에서는 데드-레코닝(Dead-Reckoning), 컴퓨터 비전 기법, 그리고 RSSI(Received Signal Strength Identification)를 사용한 모바일 센서 차량(MSV)의 지역화 정밀도를 향상시키는 방안을 제시하고, 각각의 방식들이 가진 장점을 융합하여 보다 정밀한 지역화를 할 수 있는지 살펴본다.

Mobile Sensor Vehicles, nodes of Mobile Sensor Network, are navigating for a specific, maybe unknown, region. For the precise usage of MSN, MSV has to be able to do localization by integrating information through communication by each other. In addition, MSV should be localized with various sensors equipped. In this research, we propose a set of techniques that improve accuracy using human mimic by combining and exploiting the existing techniques such as Dead-Reckoning, Computer Vision and Received Signal Strength Identification.
