Turtles to Test Wireless Network

From Discovery News.In an experiment taking place along the Deerfield River in western Massachusetts, two otherwise unrelated groups of researchers are working together: computer engineers who are testing a new wireless communication network (TurtleNet), and biologists who are tracking snapping turtles — a species they worry may be headed for decline as land development shrinks their habitat. The idea behind the technology is to create a network of constantly moving devices that record and store information, transmit data from one device to another, then relay all the saved information to a central location while running on self-charging batteries. The solar-powered computers are light enough so they don't weigh the turtles down, and they don't interrupt their mating habits, Jones said. Stuck to the shells of about 15 turtles found in spots near the Deerfield swamp, the gadgets will take periodic readings of the reptiles' location and body temperature. When one computer-carrying snapper gets within a tenth-of-a-mile of another, the machines swap information. The series of short-distance transmissions allows for long battery life in each computer, and the solar panels attached to the units are expected to constantly keep the batteries charged. Without a relay system, a longer transmission would require a larger battery that would drain too quickly or be too big for a turtle to carry. The turtle-to-turtle relay ends when one of the snappers passes near a single base station that receives all the accumulated information.Previous Post Next Post
