Title:
スケーラブルビデオの無線網を通じての電力の効率の良い伝送のための方法およびシステム
Document Type and Number:
Japanese Patent JP2006523387
Kind Code:
A
Abstract:
A method and system for reducing power consumption in a wireless network by adjusting the transmit energy for each bit at the physical layer and the retry limit at the MAC layer. The method includes creating a look-up table containing optimal pairs of Nlim,Et for a plurality of different sets of transmission properties, wherein Nlim is a retry limit and Et is a transmit energy per bit; determing a set of transmission properties for a sequence of scalable video to be transmitted over the wireless network; accessing the look-up table to obtain the optimal pair of Nlim,Et, corresponding to the set of determined transmission properties; and transmitting the sequence of scalable video over the wireless network using the accessed optimal pair of Nlim,Et.
