Abstract: Data broadcast is an efficient method for data accessing in the asymmetry bandwidth of mobile real-time environment For characteristics of such a network, we analyzed some of existing broadcast scheduling algorithms, such as UFO algorithm and propose SI3S algorithm and CRS algorithm. They improve UFO from server and mobile client. The two algorithms can automatically generate broadcast scheduling lists which depend on the given data items' probability distribution. I}hen theoretical analysis and experimental results show that the proposed algorithm can not produce any transactions' restarting and effectively reduce data items' accessing time. All of these make the average waiting time that users access data broadcast minimized.
Key words: Mobile read-time environment, Data broadcast, Broadcast scheduling algorithm
