經歷無線通訊技術及行動計算快速的成長,由於無線通訊的頻寬和能源的限制,於是提出無線廣播的議題,本論文的焦點集中於對資料項有效的進行廣播排程,以縮短用戶端的存取時間。本研究於「多項請求」的廣播模式提出二次規劃的方法。由實驗結果得知縮短用戶端的存取時間,本論文的方法可以建造較QEM方法佳的廣播排程。 Wireless communication technology and mobile computing are experiencing rapid growth. Because of the inherent restrictions of wireless communication, such as bandwidth and energy restrictions, the broadcasting method is preferred. In this work we mainly focus on effective data scheduling for wireless broadcast to reduce the access time of mobile clients. In this paper, we propose a quadratic programming method for complex-query-based broadcasting. Experimental results show that our algorithm can construct a better scheduling than QEM method in total access time.
