摘  要：
为了解决传统网络分层结构下层与层之间无法信息共享和非最优化性能等问题,通过建立链路自适应模型和跨层协议优化策略,分析对比基于链路自适应的跨层协议较传统分层网络结构的网络性能。本文设计了一种无线网络环境下基于链路自适应的跨层协议优化方法。在OPENT Modeler中实现跨层协议模型并构建仿真场景,完成了优化方法的测试验证。结果表明:基于链路自适应的跨层协议较传统分层协议在平均带宽利用率方面提高了11.6%;在传输延时方面,减少29.2%;在网络吞吐量方面,增加17.3%。总之,该方法优于传统的分层协议。

摘  要：
In order to solve the problem of the information non-sharing and the non-optimization performance among layers in the traditional hierarchical network structure, this paper designed a cross-layer protocol optimization method in wireless network environment based on link adaptation by way of establishing the link adaptation model and cross-layer protocol optimization strategy, analyzing and contrasting the performance between the cross-layer protocol based on link adaptation and the traditional hierarchical network structure. This method was realized in OPENT Modeler, built and validated in the simulative scene. The results showed that the average band utilization of cross-layer optimization method based on link adaptation was improved by 11.6% compared to traditional network hierarchical structure. In the aspect of time delay,transmission delay of cross-layer optimization method based on link adaptation was reduced by 29.2%, the proposed cross-layer method improves network throughput by 17.3%. In a word, the method of cross-layer optimization was better than the traditional one.
