中文摘要：
随着多媒体业务的不断发展,如何保证无线网络上的QoS成为一个很重要的问题.基于传统的分层设计方法很难适应快速变化的无线通信环境.主要研究无线网络QoS的跨层设计技术,分析了无线网络的特点及其QoS需求,在此基础上阐述跨层设计的思想和方法,讨论了QoS跨层设计目前存在的问题,对QoS跨层设计技术进行了展望.
英文摘要：
With the incessant development of multimedia operation, it is very important to ensure the QoS of wireless networks. The method based on traditional protocol makes it difficult to adapt to wireless communication environment with constant changes. This paper focuses on the new-style crosslayer design of QoS in wireless networks. Firstly, the characteristic of wireless networks and QoS requirements are analyzed. Then the idea and the method of cross-layer design are introduced, and the questions of cross-layer design are also discussed. Finally, the cross-layer design technique is prospected.
