Abstract:	廣播資料是行動計算環境中有效率資料廣播的一個優良方法。廣播資料已經廣泛的應用在寬廣領域，在Client端執行廣播資料上的查詢或處理，為了要用來減少處理複雜查詢的存取，我們提出一個有效率的運算法則決定在廣播頻道方面的資料分配，使時常存取的資料在查詢處理的特別命令中績效最佳化。在最後我們的實驗中可以看到假設資料欄位長度5的時候，我們的方法和電腦隨機亂數產生的資料欄位順序比較下，我們的方法比電腦隨機亂數產生的資料欄位順序有效率為10％，最後的實驗結果，可以証明我們的方法是有效率的。　　　Broadcast the data is a good method of valid rate broadcast in acting the environment of calculation. Broadcast the data is already extensively applied in the realm of comprehensiveness. At client side of broadcasting the data executing process or query, we bring up an efficient algorithm to assign the data allocation in channel of broadcast in order to reduce sophisticated access of the search. It will optimize the special command of searching data for often accessed data. Our experiment shows when assumptive data column length reaches five, our method is ten percent more efficient compare to the order of data column randomly generated by the machine. Therefore the result of experiment proves our method is more efficient.
