Since multimedia applications are known to be resource-hungry and mobile devices are resource-poor, in this paper, we propose techniques to reduce the energy consumption of streaming media applications running on mobile hosts. Our proposed techniques are proxy-based and involve power-friendly transformations on the requested streams so as to limit the energy required for receiving and decoding this data. Additionally, our proxy employs intelligent network transmission techniques to reduce the energy needs for network reception of streaming data. We implement our techniques into a prototype proxy and client and demonstrate their efficacy via an experimental evaluations. Our results show that our power-friendly transformations are effective over a range of bit rates and stream resolutions, while our intelligent transmission techniques can reduce the potential energy wastage during network reception by 65-98%.
