移动环境中实时事务数据的广播调度

提出一种基于需求广播模型的实时事务数据的广播调度策略．在本策略中，综合考虑了事务存取多个数据项和满足定时限制的要求．本策略的目标是使错过截止期的事务数量最少，对我们提出的算法，通过建立模拟实验进行评价，结果显示它比现有的策略有明显的优越性．

Data Broadcast Scheduling Strategy for Real-time Transacion in a Mobile Environment

In this paper, we propose a broadcast scheduling strategy for real time transaction based on the BoD (Broadcast on Demand) model. In the strategy, the issue of both accessing multiple data items and meeting the timing constrain of the transaction are considered. The purpose of the algorithms is to reduce the number of transactions missing their deadlines. An extensive simulation experiments have been conducted to evaluate the performance of the proposed algorithm. Results show that our broadcast algorithms achieve excellent performance comparing with existing strategies.
