Monitoring water quality through a telematic sensor network and a fuzzy expert system
Hatzikos, Bassiliades, Asmanis and Vlahavas

The article introduces an expert system that monitors seawater quality and pollution through a sensor network called Andromeda. This system is used to monitor sensor data collected from monitor stations. The data is then used to tell whether water is suitable for different uses, such as swimming. The goal of this system is t help authorities in the fight against pollution in the aquatic environment. This expert system determines when certain pollution limits have been exceeded and flags up alerts. The use of this system could someday help to monitor pollution on a worldwide basis.

Environmental Wireless Sensor Networks
Corke, Wark, Jurdak, Hu, Valencia, Moore

The article explains why there has been slow progress in using WSN. The WSN hype was triggered by the availability of low-cost low-power feature-rich microcontrollers and single-chip radio transceivers. Scientists expected a high level of system integration, performance, and productivity. The WSN is just one-part of a complex system that includes internet links from the WSN to a server, databases, and web presentation tools. Each component is critical for success and each was underestimated. It was assumed that servers were always up. Performance of the WSN has many aspects. A gap in any one of the aspects lead to gaps in the data gathered.

Environmental sensor networks in ecological research
Rundel, Graham, Allen, Fisher, Harmon

Environmental research is undergoing technological revolution as interfaces develop between environmental science, engineering and informational technology. Advances have been made possible by decreasing cost, size and weight, and improved reliability, of sensing hardware and software. The internet allows for increased connectivity to transmit and share data, with this development, an array of sensor networks are emerging to address ecosystem issues. New designs of sensor networks allow for the observation of systems in near-real time from local sources and remote sensing data streams. Ecological sensor networks are at the core of major new efforts to address issues of global change and environmental stability.

Environmental Sensor Networks: A revolution in the earth system science?
Hart, Martinez

Environmental Sensor Networks (ESNs) facilitate study of fundamental processes and development of hazard response systems. They have evolved into “intelligent” sensor networks that has a network of automatic sensor nodes and communications systems which communicate their data to Sensor Network Server (SNS) where the data can be integrated with other environmental datasets. ESNs will become a standard research tool for future Earth and Environmental Science.
