Introduction

專題主題• IEEE 802.11 Wireless LANs Quality of Service

Enhancements with bandwidth detection and Media Aware Network Element (MANE) for P2P video streaming.

中文摘要• 關於 IEEE 802.11 無線區域網路的最佳化功能，

是在嵌入式系統平臺下實作一個原生型優化步驟。• 希望在 ASUS WL-500gP AP 上，能夠– (1) 偵測出目前的使用流量，以及剩下的頻寬，

以調整目前傳輸 SVC video 的資料量，從而提升整體服務品質；

– (2) 實作 P2P video streaming 之 MANE ，以有效利用無線網路頻寬。

英文摘要• In this project, we want to implement prototypes

on Embedded System ASUS WL-500gP Router for SVC Video streaming and P2P Media Aware Network Element (MANE) for video streaming.

• We want to detection the remaining bandwidth of the WLAN more acculately to improve the QoS for SVC video streaming.

• Moreover, with this platform, we want to implement a MANE for P2P video streaming to utilize wireless bandwidth more efficiently.
