    This paper considers an overlay solution for asynchronous Medium Access Control (MAC) protocols in a duty-cycled wireless sensor network (WSN). The solution extends sleeping times and corrects time drift when the sampling rate is low. The sleeping time is adjusted according to the requisite data sampling rate and the delay requirements of the prevailing application. This and the time drift correction considerably reduced idle listening and thus also decreased power consumption. When the power consumption is reduced, the life of wireless sensor nodes extends.
