BLANE CHESNUT CHRIS DONNELLY ADAM RASMUSSEN JOHN PRITCHARD ZACH BRUCE ADVISOR: DR. AHMED E. KAMAL Wireless Mesh Bear Tracking

Project Description Wildlife Research Institute (Ely, MN) Locate and track black bears GPS solution with a transmitter to relay information on location Mesh network technology Digi products 2

Requirements vs. Wants RequirementsWants Track Black BearsUp to 1 year battery life Point location every 10 minutesLive tracking of bears Wide temperature range/ WeatherproofRechargeable Tough shell for bear cubs to chew onSoftware End User interface (Google Maps) Coverage of 25 miles x 10 milesSmart Device (power management, accelerometer, temp sensor, etc.) Appropriate Physical DimensionsSecure Communication Prototypes to Field Test by April 3

Constraints Size- must fit on the bear’s collar Wireless communication through dense woods Environment- Cold winters in Northern Minnesota Battery powered & Efficiency User friendly technology 4

Assumptions Use GPS to track location Collar communication with a base station or satellite are both viable solutions Researchers will learn to use technology Lower frequency signals travel through dense tree cover more easily than higher frequency signals Digi funded project Everyone will contribute 5
