Web based water quality monitoring with sensor network: Employing ZigBee and WiMax technologies

This paper presents the development of a web-based wireless sensor network application for monitoring water pollution using Zigbee and WiMax technologies. The developed system consists of a local Zigbee network, capable of acquiring various water quality parameters, a WiMax network and a host computer for web based monitoring. The system is designed to collect and process information, thus making decisions in realtime via a remote web server. The data is sent from sensor nodes through the Zigbee gateway to the web server via WiMax network, thus allowing users to remotely monitor the water quality from their offices instead of gathering data from the scence. Experimental results demonstrate the ability of the sensor network to monitor water pollution in real time. This system can be easily configured to support other applications, such as e-health and security.
