Water Quality Monitoring with Ubiquitous Computing

Traditionally, data collected from water quality monitoring systems are typically stored in closed repositories that are not shared with the public. Due to the cost and environmental limitations traditional water quality monitoring systems cannot collect sufficient samples to reflect the overall status of water quality. In this paper, the monitored data were transmitted in real time by WCDMA to the central server via a 3G network. In such a ubiquitous environment every user can interact with other mobile users or devices. Next, grey relational analysis is used to find the most influential water factors that help us easily realize the overall status of water resources. Experimental results verify the applicability of the proposed ubiquitous system.
