| 摘 要： | 在分析移动数据库和移动Agent各自特点的基础上，将多移动Agent技术引入到移动数据库中，结合分层、查询分解、双重身份和相似查询的思想，提出了基于多移动Agent的查询优化模型MMAQOM。MMAQOM可以减少查询次数和网络流量，改善系统的可靠性，提高整体查询效率。最后对模型的形式定义、通信机制、功能组成和算法作了较详尽的阐述。

| Abstract: | Based on analyses on the characteristics of mobile database and mobile agent,a multi-mobile-agent technology is introduced into the mobile database,combining with the thought of hierarchical layers,query decomposition,dual-role and similar query,a model(MMAQOM) based on multi-mobile-agent query optimization is proposed,which can reduce times of query and network flow,enhance reliability of system and improve efficiency of query.And definitions of model format,communication mechanism,architecture,function and algorithm of MMAQOM are presented in detail. |
