摘　　要：传统的异构无线网络环境的信息共享策略仍然是建立在紧耦合、硬绑定的交互机制和技术基础之上,基于内容的信息探测与定位能力不足,不能适应网络环境变化。论文研究了共享空间管理和分布式节点的动态组织维护与管理,及异构数据源统一访问技术,提出了基于元数据的共享策略,解决异构数据访问问题。设计与实现了一个面向领域的信息共享系统,以支持共享信息的发现和获取。The traditional data sharing model of heterogeneous wireless network is still established based on tightly cou- pled, hard-binding interaction basis and technique. Data detection and positioning based on content poor ability, and cannot adapt to changes of network. Therefore, dynamic organization, management of shared data space, and distributed index, and techniques of heterogeneous data discovering are studied, and the sharing strategies based on orignal data is proposed to deal with heterogeneous data accessing problems. An information sharing system is designed and implemented to support the dis- covery and obtain of shared information.
