Standard sensor networks waste battery power because they are designed to continuously poll for data, making them unsuitable for long-term use in applications that must detect and respond to unpredictable events. To solve this, a hardware-software technique called lucid dreaming was designed, implemented, and evaluated for a structural autonomous crack monitoring application in civil engineering. The technique dramatically reduces sensor node power consumption by enabling high-resolution sampling only in response to aperiodic vibrations in buildings and bridges, rather than running continuously.
