Presentation Transcript

  1. Wireless Data Acquisition and Routing in By Clifton Bradley, Brian Kessler and Ryan Vinelli

  2. Programming the Mica2 Motes • Used SensorToRfm as a base to send a packet of sensor readings for: • Temperature • Light • LED • Use Surge for Multihop routing

  3. Planned Functionality • Broadcast Sensor Readings to Base Station • If N-hops away have (N-1)-hop motes route packets • LEDs will indicate transmissions. • Use a Simple Routing Scheme • The multi-hop implementation consists of two core modules, and uses a shortest-path algorithm • Base Station will run a simple Java program (based off of Listen.java) to display Mote ID and Sensor reading

  4. TOSSIM/TINYVIZ • No available Mica2 Motes so emulated environment: • /opt/tinyos-1.x/tools/java/net/tinyos/sim • tinyviz –nosf –nolaf -run build/pc/main.exe 30

  5. Problems • Environment • Fedora 5 (Java Comm issues – found from toscheck) • Windows XP with Cygwin Installer (worked) • Emulation • TinyViz Java runtime errors • Generating Nodes that do what I want
