Due to the recent development of wireless sensors, many studies exploit rounding data sinks to collect data from sensors. A rounding data sink rounds in the sensing field and collects data from each sensor. The rounding sink approach can reduce communication traffics and maintenance costs compared with the conventional sensor network approach. Although some methods for the rounding sink approach have been proposed, they do not consider the data amount that each sensor has. This causes a problem that the rounding sink collects only a little data from some sensors even if they have a large amount of sensor data. In this paper, we propose a data collection method considering the data amount that each sensor has. In our proposed method, the rounding sink calculates the data amount to collect based on the data amount that each sensor has. We demonstrate that our proposed method can give fairness to the amount of the collected data.
