摘要

提出混合式数据同步机制，有机融合集中式和ad hoc架构，设置自组织域(SOD

self-organization domain)，减少了同步数据通信量和数据同步服务器负载；提出基于节点能力值的数据分发策略，根据移动终端综合处理能力值来建立 SOD 树分发路径，实现同步数据的高效分发；还提出了基于轨迹变更的增量捕获策略，采用触发器捕获操作日志，用净化方法合并操作日志得到净增量数据。实验结果表明，混合式数据同步机制能更好地维护移动计算环境中数据的一致性，缩短同步响应时间，减少同步数据通信量，降低同步服务器负载。

Abstract

The hybrid data synchronization mechanism (HDSM) was proposed

which integrates centralized architecture and ad hoc architecture together

and a series of self-organization domains (SOD) were built as to cut down the traffic of synchronization data and lighten the load of synchronization server.The capacity-value-based data distribution strategy was proposed

which establishes data distribution paths of SOD tree based on the comprehensive processing capacity of mobile nodes to implement the high-efficient data transmission.The increment capture strategy based on track changes was proposed

which captures operation logs with triggers and obtains pure increment data by purification.The experi-mental results show that HDSM can make maintenance of data consistency better in mobile computing environment and shorten the response time of synchronization

and reduce the traffic of data synchronization and the load of synchroniza-tion server.
