适合无线自组网的QoS体系结构研究

Research on QoS Architectures for Wireless Self-organized Network

随着移动无线网络技术的发展和多媒体业务的普及,在无线自组网上保障业务的服务质量(QoS)已成为备受关注和急需解决的热点问题之一。文中提出一种适用于无线自组网的QoS体系——FQAW,试图提升无线自组网的QoS保障能力。首先,说明了在无线自组网中采用QoS体系结构的必要性。然后,详细说明和分析FQAW体系结构的设计理念、网络结构、功能部件和相关机制。分析表明基于分簇网络结构的FQAW可提高无线自组网的可扩展性和服务质量保障水平,但是还需借助于计算机模拟和现场试验等方法来评价QoS网络体系结构的优劣。

With the development of mobile network technologies and popularity of multimedia services, QoS guarantee in wireless self- organized network （ WSON ）. has become one of burning issues. In this paper, a kind of QoS architecture sutiable for WSON named FQAW is proposed to improve QoS support capability in WSON. Necessities of adopting QoS architecture in WSON are explained first ly. Then, design ideas, network structure, functional components and relevant schemes of FQAW are exounded and analyzed in detai. 1. It is shown form analysis that FQAW based on clustering network structure can ehance scaiability and QoS level of WSON. However, proposed QoS architecture should be evaluated by using computer simulations and field experiments.
