Zero-power design for Smart Dust networks

This paper addresses the low-power design of distributed sensor networks for intelligent measurement. We present a method for system clock optimization based on behavioural requirements and a power-saving mode. Essentially, the suggested approach minimizes the power consumption and provides longer battery lifetimes. In addition, the method improves the electromagnetic compatibility which is crucial for cubic-millimeter nodes. The zero-power theme goes on with passive reflector communication systems. We discuss an approach for zero-power orientation of corner-cube retroreflectors.
