移动数据库高效事件检测方法研究

移动数据库中,大量的事件分布在不同的结点上,产生的事件具有分布、并发、异步、随机的特点,事件源通常是移动主机,事件的到达因网络连接的不稳定以及移动主机的移动而发生时延、失序的情况。本文提出了一种新的检测方法,能够高效地进行分布式检测、并发异步事件的检测、失序事件的检测以及断接检测、移动检测。

Research on the Events Detection of the Mobile Database

An amount of events in the mobile database are distributed on different nodes, so they are characterized by distributed, concurrent, asynchronous and stochastic. Mostly the source of events are mobile host, and the arrival of events always delay and disorder according to the instability of internet and removal of the mobile host. A new detection method is introduced in this paper, which can detect some concurrent and asynchronous events, disordering events, also which can do some interruption of contact detections, mobile detections, and distribute detections efficiently.
