摘　　要：随着网络应用需求的不断增加,网络提供的可用资源也变得越来越复杂,因此对于网络资源的定位与发现工作也显得越来越重要,目前已有多种方法被提出并被讨论过,这些方法在固定式网络中使用效果较好,而对于应用日益普及的Adhoc网络来说并不适用,本文就Adhoc网络中的资源发现与获取方法提出了一种新的、基于Agent的模型,在模型中提出了QoS信息路径的产生与管理方法。With the rising popularity of network-based applications and the potential use of mobile ad hoc networks in civilian life, an efficient resource discovery service is needed in such networks for quickly locating resource providers. In addition, to improve user experience, QoS awareness is also crucial. There are several methods in resource discovery, but they are not suitable for the ad hoc network. In this paper, a new architecture is put forward. The key technology is self-organized discovery agent. These agents manage the directory information of resources using hash indexing. They also dynamically partition the network into domains and collect intra- and inter-domain QoS information to select appropriate providers. In the last paragraph, the future research is mentioned too.
