在無線環境下以不同基地台選擇不同影片選擇多重速率進行群播

Multicast multiple video in multi-rate wireless environment

指導教授 : 周承復

摘要


現今手持式的電腦設備,例如智慧型手機,平板電腦等等...越來越普及。 對於手持式電腦裝置上多媒體的需求也在增加。 從基地台傳送多媒體到手持式電腦裝置時, 如何有效率的使用無線基地台的頻寬就變得十分重要。 而在多重基地台,多重傳輸速率環境下進行群播是更加複雜的問題。 在這篇論文中,我們闡述了這個問題,並且提出一個創新的效用導向演算法, 在比較過傳統的方法後,我們的演算法表現會比傳統的演算法好。

Mobile devices, such as smart phone, and tablet PC are more ubiquitous. The demand of multimedia content on mobile device are increasing. How to utilize base station and bandwidth in wireless environment while transmit multimedia content becomes very important.The method of multicasting video in multiple base station, multiple transmission rate environment is even complex.In this paper, after we formulating this problem, and compare some traditional algorithms.Finally, we propose an novel utility-based algorithm which outperforms all other traditional algorithms.
