Broadcast scheduling algorithm of multiple channels and data items based on request
基于请求的多信道多数据项广播调度算法*

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.
