| 摘 要： | 传统分布式网络中协同检查点算法有许多优点,但移动计算环境有很多新问题,如缺少可靠存储、低无线网络带宽、高移动性、断开连接和能量限制等,使得协同检查点算法不能很好地适用于移动计算环境.为此提出一种适合移动计算环境的非阻塞的协同检查点算法,算法中检查点的发起和同步由移动支持站完成,只需记录部分中途消息就能实现一致可恢复.算...

| Abstract: | Although there are many advantages for coordinated checkpoint,mobile computing environment raises many new issues such as lack of stable storage,low bandwidth of wireless channel,high mobility,frequent disconnection and limited energy.These make the coordinated checkpoint algorithms unsuitable for mobile computing.This paper proposes a non-blocking coordinated checkpoint algorithm,the startup and synchronization of the coordinated checkpoint are completed by mobile support station.The algorithm is transparent for mobile host,and low-overheard and consistent rollback-recovery only save part of in-transit message. |
