无线网络的跨层设计

Cross-Layer Design in Wireless Network

无线网络信道易变化,同时还有QoS的需求,传统的分层设计不能根据变化做动态调整,引入跨层设计的思想,可以提高交互性。对无线通信环境的特征进行介绍,结合QoS的要求,给出跨层设计的思想。最后提出一种跨层设计的框架,将自适应协议引入其中,可以适应信道变化,提高网络资源的利用率。

Analyses the elvaracteristic of the wireles, network. Combines the need of QoS. Introduce the idea of cross layer. Based onthe detailed description of the cross layer design in the wireless network,put forward a framework of the cross layer design. It can adjust the variations of the eharmel,so it improves the coilization of the network resource.
