모바일 환경에서 수질관리 모니터링 시스템 구현

Water Quality Monitoring System using USN effectuates real time remote monitoring by way of pollution measuring instruments and sensors in anytime, anywhere. It allows preventing the spread of contamination by early examination of various environmental conditions. This paper shows the realization of USN middleware for applying data obtained from utilization of heterogeneous sensor node to Water Quality Monitoring System. Actually, USN middleware allows abstraction of heterogeneous sensor node, data filtering, and event processing etc. We implement Water Quality Monitoring System to monitoring based on PC and mobile equipments including smart phone. The goal of research focuses on Water Quality Monitoring System by smart phone. Also, we estimated the usability of Water Quality Monitoring System through analyzing its efficiency, and also tried to improve the reliability of the system by minimizing the overhead and response time.
