Ridgeline Meteorological Sensor Network Stephen Copeland, Xau Moua, Joseph Lane Advisors: Dr. Manimaran Govindarasu, Dr.Venkataramana Ajjarapu
Problem Statement Small scout towers capable of wirelessly transmitting measurements to large MET towers. Wireless communication via radio transceivers on scout tower and MET tower. Built-in mesh networking protocol
System Block Diagram
Transceiver Solution XBee-PRO DigiMesh 900 Transceiver Transmit Power 50mW LOS Range 6 miles (w/ High gain antenna) Built in mesh Yes Cost $45.00 Pros Build in mesh protocol Scalable and interoperable w/ devices from different vendors UHF can penetrate dense forestry Self-healing and discovery for stability Cons Highest price XBee-PRO DigiMesh 900 Transceiver
Antenna Solution 7" half wave, bulkhead mount, RPSMA connector
Microcontroller Solution
Testing Range Power consumption Microcontroller various locations on campus Power consumption Use of LabView and multi meters to measure current and voltage levels Microcontroller Basic data communication Message integrity Throughput
Testing (cont.) Self Healing Security Latency Casing Selected modules turned off during transmission Security Channel hopping, Encryption, Latency Receiving rate vs. data size Casing Shock, vibration, realistic impact, and submersion in water.
Current Status Transceivers and antennas received Documentation Finalized Proposal for acquisition of used sensors Initial communication testing More unit and system level testing is required
