Abs?ruct-PicoWireless Networks [l]are being proposed
in applications such as environmental monitoring, intruder
detection and smart buildings. However, the two main
challenges of PicoWireless Networks are energy and
bandwidth. This paper describes the design of cluster
formationand optimizationof network managementin order
to prolong the life of Pic0 Wireless Sensor Nodes and
increase their bandwidth. The paper also describes the node
architecturetargeting an SoCplatform.
Recent advancesin MEMS technology,RF circuitry and
signal processing have brought this idea of small,low-power
wireless devices ever closer to reality [I]. Pic0 Wireless
Sensor (F'WS) nodes [I] are very small devices, tpically a
