Research Abstract	In this study, we investigated the low power consumption of wireless sensor networks which can be applied in various fields such as environmental monitoring and agriculture. If the wireless sensor networks developed to a large area such as rice field, it is a issue that how reduce the power consumption of a terminal for relaying data. The relay terminals, it is always waiting for receive data. Because it does not know when the data will come. This waiting time consume many power. By making intermittent operating a wireless function, it is possible to reduce the power consumption. When the frame time (the total time of ON and OFF) is longer, we found that it is possible to reduce the power consumption and maintain the arrival rate of the data.
