Design methodology for PicoRadio networks

One of the most compelling challenges of the next decade is the "last-meter" problem, extending the expanding data network into end-user data-collection and monitoring devices. PicoRadio supports the assembly of an ad hoc wireless network of self-contained mesoscale, low-cost, low-energy sensor and monitor nodes. While technology advances have made it conceivable to deploy wireless networks of heterogeneous nodes, the design of a low-power, low-cost, adaptive node in a reduced rime to market is still a challenge. We present a design methodology for PicoRadio Networks, from system conception and optimization to silicon platform implementation. For each phase of the design, we demonstrate the applicability of our methodology through promising experimental results.
