| 摘 要： | 当前移动计算技术研究中索引技术与移动事务处理方法相对独立,即传统的索引技术并不支持对移动客户端移动事务的并发控制,而现有的基于数据广播的移动事务处理方法主要针对保持数据一致性而设计,并未考虑事务处理过程中的节能问题。将分布式索引技术应用于移动事务处理,提出一种在数据广播环境下同时实现移动事务并发控制和节能处理的有效方法。实验结果表明该方法的平均调谐时间为未应用索引技术前的15.5%。

| Abstract: | Two main research directions of mobile computing are relatively independent.The traditional indexing methods do not support concurrency of transactions issued in mobile clients,and the existed methods for broadcast-based concurrency control do not care the problem of energy efficient.By applying the distributed indexing methods to mobile transaction processing,an energy efficient method for broadcast-based mobile transactions processing is designed.Simulation results show that the average tuning time of this method is as little as 15.5% of the average tuning time in the mobile transactions processing without indexing. |
