Abstract

River water pollution monitoring is becoming an increasingly important task for environment agencies. The challenging is that very large area needs to be surveyed event for a relatively small section of the river. Furthermore, dynamic changes of the environment condition require real time sampling of the parameters. Unmanned monitoring station network has limited resolution. Deployment of water quality monitoring vessel is extremely expensive. We have developed a practical solution that uses networked agents to achieve near real-time river pollution monitoring. The agents are autonomous/passive in situ measurement floats that can be deployed from the upper stream of the river. The ideal is that when the floats travel down stream the river, the sensors on board will sample and analyze the physical and chemical parameters. The GPS position and the data from the sensors will be uploaded to the base via GSM network. The trajectory of the floats and parameter changes can therefore be dynamically updated using Google map graphical overlay This paper presents the design, implementation and testing of the system.
