Energy Efficient Multimedia Streaming to Mobile Devices - A Survey
Energy conservation in battery powered mobile devices that perform wireless multimedia streaming has been a significant research problem since last decade. This is because these mobile devices consume a lot of power while receiving, decoding and ultimately, presenting the multimedia content. What makes things worse is the fact that battery technologies have not evolved enough to keep up with the rapid advancement of mobile devices. This survey examines solutions that have been proposed during the last few years, to improve the energy efficiency of wireless multimedia streaming in mobile hand-held devices. The authors categorize the research work according to different layers of the Internet protocol stack they utilize. Then, they again regroup these studies based on different traffic scheduling and multimedia content adaptation mechanisms.
