整个无线通信演示系统由ABCD四个节点组成,根据硬件前端的实现,每个节点在收到与自己地址对应的数据包时触发同步信号,所以就需要一个中心节点来进行同步触发,本系统中以A节点为中心节点,B、C、D三个节点地位对等。A节点周期性的广播同步信息,从而实现四个节点的同步。A节点连接一台PC机,用来监视网络的情况并显示从其它节点发送过来的图像流信息。该软件可以实时对串口进行监听并显示A节点的路由表、网络的时隙表和吞吐量,实时获得B、C、D三个节点的图像流数据。-The wireless communica

模拟两级复制算法,引入了将系统进行分级的思想。该算法充分考虑了典型的移动计算环境中可信部分和移动部分的性能差异,将整个移动计算环境分为两级,第一级是通过固定网络保持连接的基结点,每个基结点维护数据库的一个副本,且这个基结点是大部分数据对象的结点,此级复制是基结点之间的复制。第二级为时常处于断连状态的移动结点,它们有时候通过无线网络与基结点相连接,有时处于断接状态,也存有数据库的部分副本,此级复制是指移动结点与基结点之间的复制。这样,可信部分总能保持传统分布计算环境下的若干特征,而不会因为移动计算
