摘要
802.16mesh回程网拥有广阔的应用前景。本文提出了一种该网络的跨层设计框架,其特点是:充分考虑下三层参数间相互影响、相互制约的关系,便于联合优化的开展;利用802.16现有信令和其它方式,实现了跨层信息交互;引入管理机制保证多种跨层设计算法并存时的一致性。这使得802.16mesh回程网中能够应用跨层设计的最新成果,适应动态变化的无线环境,同时满足自适应的要求,提高网络性能。
This paper proposes a cross-layer design framework of 802.16 mesh backhaul networks, which has a bright future of application, Firstly, in order to optimize system performance, it researches the mutual impact among the physical, MAC, and network layers. Secondly, it uses 802.16 signal system and other ways to implement the cross-layer interaction. Thirdly, it introduces a control system to keep the consistency of different cross-layer designs. The framework can adopt the latest cross-layer designs, so as to dynamically adapt to the changing environment of wireless channel, and improve network performance.
