摘　　要：在移动环境下 ,服务器采用何种数据结构向客户端传送信息直接关系到移动系统的效率 .本文基于 Hu-Tucker算法而提出的选择调谐方法将有效降低 AT和 TT.其基本思想就是根据记录的使用频率构造最优查找树 .In a wireless computing environment, which kind of structure the server rely on to disseminate the information to the clients directly determines the efficiency of the mobile system. In this paper, based on Hu Tucker algorithm, we propose a selective tuning mechanism which will decrease the AT and TT effectively. Our basic idea is to construct an index tree according to the using frequency. Our theory derivation and simulation study!demonstrate that this scheme can give us a better results than ever.

关 键 词：Hu-Tucker算法 调谐时间 调谐模式 数据结构
