Abstract: Mobile Ad-hoc Networks（MANETS） is a net that has instability，low bandwidth and high query latency.Coordinate cache technique is adopted broadly to achieve high quality data distribution and data share in MANETS.However the coordinate cache technique incurs the data inconsistency frequently.To resolve the problem of data inconsistency in MANETS，the paper proposes a coordinate algorithm that uses mobile window to predict the chosen cache nodes.Simulation results show that MWCC can adaptively resolve the problem of data inconsistency and reduce the cost of data distribution and data share.

Key words: Mobile Ad-hoc Networks（MANETS）, coordinate cache, consistency, mobile window, adaptive, predictable

摘要： 移动自组网络（MANETS）是一种具有弱连接性、低带宽、高查询延迟的网络。协缓存技术被广泛用来实现MANETS中数据的高效分发与共享，然而协缓存技术极易引发数据不一致性。为了有效解决现有MANETS中存在的数据不一致性问题，提出一种使用移动窗口来预测选定缓存节点的协缓存算法（Mobile Window Caching Consistency，MWCC）。实验表明，该算法能有效解决MANETS中因协缓存技术带动来的数据不一致性问题，并在很大程度上减少了通信拥塞与查询延迟。
