Abstract:
The
Quark node combines off-the-shelf components and two custom CMOS chips to
implement a PicoRadio wireless sensor-network
node that runs solely from energy scavenged from the
environment. The node supports a >10m indoor transmission range
with automatic multi-hop routing for longer distances. Node functionality
includes a 50kbps on-off keyed physical layer, a cycled-receiver MAC algorithm
with dynamic ID assignment, a directed flooding network routing algorithm, and a
Hop-TERRAIN location computation algorithm. The first custom die is a 0.13µm
CMOS digital processor for the baseband, data-link, network, and application
layers of the protocol stack. The second custom die is a 1.9GHz two-channel
transceiver designed in 0.13µm CMOS for peer-to-peer communication. The 1.9GHz
antenna is implemented as a board trace to reduce node cost.
