Requested-QOS driven runtime reconfiguration of mobile devices
The present paper embodies a technique for on-the-fly remote reconfiguration of mobile device for power optimization according to the requested quality of service (RQoS) from user. The method is initiated by mobile device user who sends RQoS parameters to remote server, where the multimedia algorithms are re-optimized as per RQoS, and a new bit-stream is transmitted to reconfigure the device for low power with acceptable degradation in quality. Experimental results show that the approach is able to reduce bitwidth by 64.31% to 73.95% for varying PSNR from 40dB to 26dB. Much higher power savings can be achieved if user is willing to tolerate more quality degradation.
