基于请求的多信道多数据项广播调度算法*

通过改进多信道单数据项请求的数据广播调度算法中的两层调度策略，提出了信道分配+QEM的算法；实现了用多信道广播来广播多数据项的请求；通过减少数据访问冲突和信道跳转减少了访问时间。分析证明此方法是可行和有效的。

Broadcast scheduling algorithm of multiple channels and data items based on request

This paper proposed an algorithm of channel allocation +QEM by improving the two level optimization scheduling algorithm (TOSA) in data broadcast scheduling algorithms, where transmitted the single-item requests through multi-channel. The multiple data item requests could be broadcast in multi-channel by using the improved algorithm. The access time was also reduced by decreasing the data access collision and channel jump. It was analytically proved that the algorithm of channel allocation + QEM is feasible and effective.
