Wireless Data Acquisition and Routing in

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

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

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
