摘要

近年來，無線區域網路透過聰明天線系統來增加傳輸效能及節省電量是熱門的研究議題。本論文在聰明天線系統上開發高效能的排程演算法，考量不同資料量的連線及干擾對平行傳輸的限制，達到減小整體網路的等待時間及提高網路總流量等目的。

並列摘要

Exploiting smart antenna systems to improve both the network throughput and power efficiency is a promising issue for WLAN. This paper aims at developing a transmission scheduling scheme with smart antenna systems. The proposed schemes take into account the interference restriction and packet sizes for minimizing the average latency and maximizing the network throughput.
