| Summary: | 碩士 === 國立成功大學 === 資訊工程學系碩博士班 === 90 === In wireless environment, if query results are scheduled with time constraint,traditional Broadcast and On-demand technologies can not guarantee that mobile can access query results within time constraint.Hence, we design new channel scheduling technology,specially for scheduling query results with time constraints,and we called time-constraint channels.We design scheduling algorithm called TFT-Based Schedulig Algorithm}which can use minimum channels and satisfy all time constraint when mobile useraccess query results.And then, we consider three factors which will affect schedule(Duplication data, Data Order,and Limited Channels),and design scheduling algorithm to minimize the number of used time-constraint channels.
Within the consept of using minimal channels,experiments and results with this concept are also presented in this paper.
