摘要
服务发现与资源定位是移动环境下进行信息共享、处理的前提,服务描述和服务匹配策略是其中的关键问题,服务的多样性、异构性以及移动环境的动态性使得这些问题更加复杂。该文提出一种支持服务多样性和异构性的服务描述模型,针对此模型设计并实现了高效的存储结构和包括精确匹配、部分匹配的服务匹配策略,实验结果表明该策略的服务匹配性能优于基于XML的XPath方式。
Service discovery and resource location are prerequisites to information share and processing in mobile environment where service description and matching are the key issues which become more complex due to diversity and heterogeneity of services, as well as volatility Of mobile environment. This paper presents a service description model for various and heterogeneous services, designs implements the efficient storage and sarvice query for this model which includes accurate matching and partial matching. Experimental results show the service matching exceeds XPath for XML-fashion services in query performance.
