Abstract: To solve the low energy efficiency problem of LTE wireless streaming media terminal,a new energy-efficient streaming media transmission control method based on dynamic buffer threshold adjustment (DBTA) was proposed.This algorithm adaptively adjusts the buffer lower threshold of receiver according to the monitored network bandwidth and streaming media encoding rate information,making the size of the buffer space more fit the current bandwidth and streaming media encoding rate,and improves the time ratio of dormant to work ,thereby extending the life of the terminal.Simulation results show that this algorithm (DBTA) can effectively resolve the problems of the excessive energy consumption of LTE wireless streaming media terminal,and achieve up to 22% energy saving.
