We have used MICA and MICA2 Motes designed by UC Berkeley as a testbed for wireless sensor network experiments. The hardware can be ordered from Crossbow. They are running an event-driven operating system called TinyOS. Motes can be used as stand alone nodes. They can also be connected with PC/104s or Staytons to form a tiered architecture.
