摘要
为了向无线多跳自组网的规划与设计提供依据,分析了物理层网络编码和网络编码分集对无线多跳自组网连接性的影响.通过对网络可供维持的路由跳数的理论推导和数值分析发现,与物理层网络编码协作发射相比,网络编码分集协作发射能极大地提高系统可供维持的路由跳数,其增益达3以上,极大地增强了网络连接性,从而提高了网络的吞吐量.
To provide a reference for planning and designing wireless multi-hop ad hoc networks,the influences of physical-layer network coding and network coding diversity on the connectivity of wireless multi-hop ad hoc networks were analyzed.The theoretical and numerical analyses of the network sustained routing hop were carried out.The reserach result shows that compared with a physical-layer network coding cooperative transmission,the network coding diversity cooperative transmission can improve the sustained routing hops in wireless multi-hop ad hoc networks greatly,and the gain can be up to above 3 to greatly improve network connectivity to enhance network throughput.
