The results show how by using Adapt-or-Handover the users benefit from up to 31% energy savings with insignificant degradation in quality, in comparison with other energy efficient solutions. ...
In this context we propose Adapt-or-Handover, a hybrid multimedia delivery solution, which balances the benefits of multimedia content adaptation and of network selection in order to decrease power consumption ...
The authors of [28] [29] propose the use of a proxy server that performs on-the-fly transcoding and dynamic adaptation of the video content (brightness compensation) based on the feedback from the ...
