In mobile distributed systems
the data on air can be accessed by a large number of clients. This paper
describes the way clients access the wireless broadcast data in short latency.
We define and analyze the problem of wireless data scheduling. And we propose a
measure, named QueryDistance(QD), which represents the degree of coherence for
the data set accessed by a query. We give a practically usable method named QEM
which constructs the broadcast schedule by expanding each query's data set in
greedy way. We also evaluate the performance of our method by experiments.
