Pattern-MAC (PMAC) protocol, instead of having fixed sleepwakeups,
the sleep-wakeup schedules of the sensor nodes are
adaptively determined. The schedules are decided based on a
node’s own traffic and that of its neighbors.

Commercially available active noise control headphones rely on fixed analog controllers to drive "anti-noise" loudspeakers. Our design uses an adaptive controller to optimally cancel unwanted acoustic noise. This headphone would be particularly useful for workers who operate or work near heavy machi ...
