Abstract :
In this paper, we propose a novel low-power listening scheme that is comprised of non-deterministic preamble sampling periods and demonstrate how the mean of these sampling periods can be varied through the use of a preamble sampling probability parameter. This is in contrast to the existing literature which treats the preamble sampling periods as deterministic and seeks to vary them directly using heuristic algorithms. Per packet energy consumption analysis and accompanying simulation results for our non-deterministic approach are provided and we show that energy consumption can be minimized by varying this preamble sampling probability parameter.
