摘要
在移动环境下,为提高多数据项请求广播的时效性,使移动用户能在有效期内访问到所需数据信息,本文对广播内容的选择进行了研究,提出了新的广播内容选择方式,并对多数据项请求广播调度算法QEM(Query Extend Method)进行了改进。试验结果表明改进后的算法进一步提高了多数据项请求广播的时效性。
In mobile environment, in order to improve time efficiency of multiple data request, make the client access data information in the period of validity. This paper research the choice of broadcast content, propose a new method of broadcast content choice, and improve the algorithm QEM(Query Extend Method). Finally, experiment results show that the improved algorithm can increase the time efficiency efficiently.
