<p><P>PROBLEM TO BE SOLVED: To reduce stanby power effectively and prevent an influence on throughput. <P>SOLUTION: In a step (1), a terminal station goes into a receive standby state for standing by for data coming from the other station. When receiving data from the other station in a step (2), whether the data are addressed to a self station or the other station is determined in a step (3). When it is addressed to the other station, the terminal station returns to the receive standby state. When it is addressed to the self station in the step (3), a time when the data reached are stored in a step (4), and an anticipatory attain timeΔt is calculated. When the anticipatory attain timeΔt can not be calculated, the terminal station returns to the receive standby state, and a differential timeΔT with the former time is gathered. When the differential timeΔT for calculating the anticipatory attain timeΔt is gathered in a step (5), a sleep state is carried for the anticipatory attaining timeΔt. By using the receiving interval of former data, the attain time of the following data is anticipated and received power is controlled to save power effectively. By anticipating the attain time of the following data, an influence on throughput is reduced as compared with a conventional power saving mode because factures of receiving the data are decreased. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
