Preemptive Scheduling for Multi-item Queries in On-Demand Data Broadcast

Zhuoyao Zhang, Weiwei Sun, Ping Yu, Yongrui Qin
2008 2008 The 9th International Conference for Young Computer Scientists  
In this paper, we propose a preemptive scheduling method for multi-item queries in on-demand data broadcast. It breaks through the previous pattern.  ...  Most previous works solve the problem under the pattern that at each broadcast moment, the server broadcasts a number of data items which constructs a broadcast cycle with fixed length.  ...  Lots of works on efficient schedule methods has been provided in previous researches both in broadcast mode and on-demand mode.  ...
