摘要： 介绍了一种新的移动AdHoc网络中使用的基本资源发现技术和一种新的架构来提供统一的资源发现和资源提供者的QoS-aware选择的解决方法。架构的关键在于一系列的自组织发现代理。这些代理使用哈希索引来管理资源的目录信息。将网络动态划分成数个域,并且选择内部和外部QoS信息来选择适当的提供者。模拟试验表明,该架构改善了QoS到客户端的传输,使开销和相应时间保持在一个低水平上。

Abstract: This paper identifies the challenges when basic resource discovery techniques for the Internet are used in mobile ad hoc networks, then introduce a framework that provides a unified solution to the discovery of resources and QoS-aware selection of resource providers. The key entities of this framework are a set of self-organized discovery agents. These agents manage the directory information of resources using Hash indexing. They also dynamically partition the network into domains and collect intra- and interdomain QoS information to select appropriate providers. Simulation results show that the framework improves the QoS delivered to the clients, while the cost and response time are kept at a low level.
