中文摘要：

在分析现有的Ad Hoc网络服务发现方法的基础上,提出一种基于语义的Ad Hoc网络服务发现方法。该方法基于语义推理机制,能对服务进行准确地刻画,大大提高了查准率;又由于该方法在考虑服务本身的同时,还考虑了服务的节点属性和节点所处的环境属性,可以有效地改善服务质量。仿真结果表明,与同类的Ad Hoc网络服务发现方法相比,该方法在查准率方面具有较大的优越性。

英文摘要：

Following the analysis of existing service discovery methods for Ad Hoc networks,this paper proposes a service discovery method based on semantic in Ad Hoc networks. Based on semantic reasoning mechanism,the method can accurately depict the service and greatly improve the precision ratio. The quality of service can be effectively improved,because the method not only considers the service itself,but also considers node properties and environment property of node. The performance of simulations shows that it is better than those similar service discovery methods proposed in precision ratio.
