| Abstract(in English) | In ubiquitous environments, wireless-sensors are effective because their weight is light and user who wears them can go wherever one wants to go. Although the life time of the wireless-sensors is limited by capacity of a battery. For extending the life time of the wireless-sensors, extending the polling interval is effective. However, if the polling interval is longer, the number of fail of sensity is higher. In this paper, we propose three methods which make life time of wireless-sensors long without fail of sensity using the sensors only at need. First method uses DB which has location where user can get important data. Second method makes the polling interval short when user who wears accelsensor moves. Last method combines the concept first and second. We implemented three methods and evaluated the utility of these by experiments. |
