Method and system for power efficient transmission of scalable video over wireless networks

摘要

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 N_lim,E_t for a plurality of different sets of transmission properties, wherein N_lim is a retry limit and E_t 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 N_lim,E_t, 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 N_lim,E_t.
