A mote is
a small, low power, single board data acquisit
ion computer with a radio
for wireless communication. Usage of the term “mote” apparently first appears
in U.C. Berkeley’s Smart Dust development project.
The evolution of the mote hardware platform will be traced from the original
Berkeley “Smart Dust”
concept through the current state
art Moteiv Telos
B devices and on to speculation about future motes. The hardware
characteristics and capabilities of the Telos Rev B mote will be examined in
The ZigBee Alliance of over 120 companies has
developed standards for the
hardware and lower layers of the communications protocol expressed in the
recently approved IEEE 802.15.4 standard. The open source TinyOS Operating
System is used by more than 500 organizations on 12 platforms to provide
r layer protocol support and general operating system support for the very
limited memory and processing power provided by a mote.
Several tutorial applications provided by Moteiv for the Telos B mote and TinyOS
will be demonstrated. The first is a simpl
e counter that transmits its data from a
remote mote to a gateway mote connected to a PC. The second application is
an Oscilloscope simulator that acquires a number of channels of data and
transmits it to a PC via a gateway mote. The PC runs the Java
SerialForwarder that makes the data available to local or networked applications
that can display the data in a time vs. amplitude oscilloscope display. Signals
corresponding to the temperature and humidity at the mote will be displayed.
An external g
as sensor will be attached to the mote and the sensor’s response to
rubbing alcohol will be demonstrated.
