Wireless sensor network for telemonitoring river bed eco-systems In view of the increasing importance of international problems related to scarcity of natural waters and increasing climatic changes, the establishment and provision of a real-time sensor infrastucture in all waters - involving river, stream and catchment areas - will be one of the major science barriers and research possibilities of the coming years. In spite of a number of technical advancements in the field of transducers and cordless transducers, a trench divides what is available from standard cordless product and what is needed by researchers for the rugged, simple operation of a surveillance network over flowing water. Consequently, the visions of real-time information flowing continually from distant detectors to lab server are still difficult for most researchers to grasp today.

In order to simplify the investigation of water-based networks of transducers, we develop hard- and softwaresystems that offer the following functions: Supports a wide range of different types of transducers. Fluvialists are interested in many different facets of aquatic ecosystems. An unexpressive shortlist of desired detectors include submarine camera, hydrophone, submarine microphone, submarine grade detector, thermometer and gemstones.

Expenditure for the use of water-based measuring instruments is motivating a constantly working sensory group. Our energysupervision technology makes it possible to scale system output according to the amount of available PV heat. Implemented software supporting service scale. The system prototypes use low-power but compute-intensive hard disks to drive more powerful but more powerful devices.

The ability to quickly identify a failing hub becomes more important as your business grows. At Amherst, we are planning to purchase, construct and operate a solar-powered fluvial sensing system over a four-mile section of the Fort river (see illustration below). Our test bed essentially comprises (i) a terrestrial, solar-powered, meshless wired gateway ecosystem, (ii) solar-powered, multi-radio capable sensing platform for convenient and rugged communications, (iii) interfaces and sensing platform for sensing surveillance signals, and (iv) supporting infrastructures.

Amherst's IT division has set up a Cisco point of entry on the Fort River for this and our test bed will offer four extra points of entry over the 4 miles as web-services.

Complementing CS research, our test bed allows researchers to study current pattern (above and below ground), velocity, profundity, temperature, siltation, transient absorption, solute oxidation, phosphorous, bacteria as well as fishing motion pattern, communal structures and biologic interaction such as predators, spat migration. Visual representation of the test bed for the flow sensing system and the Fort river event location for its use.
