摘　　要：以移动Ad-hoc网络中无线跳频频率资源规划为研究背景,针对组网场景复杂多变、多频表混合使用、频表中频点数量不统一、子网间存在频率间隔要求等问题,基于网络拓扑抽象出三种基本组网场景,并定义节点集、子网集、组网集,实现对复杂组网场景统一描述,在此基础上,构建频率规划求解模型,实现多节点、多子网、多频表资源协同规划,降低了频率资源统筹规划难度,提升了频率规划效率。并且,从理论上回答了在给定频率资源和约束条件下,能否为网络拓扑中所有子网分配出频率资源的问题。With wireless hopping-frequency planning in mobile Ad-hoc network as the research background and aiming at these problems,such as complex and variable networking scenarios,mixed use of multiple frequency tables,inconsistent number of frequency points in the frequency table,and frequency spacing requirements of between the subnets,and based on the network topology,the three basic networking scenarios are abstracted,the node set,subnet set,and network set defined,and a unified description of complex networking scenarios realized.On this basis,the frequency planning solution model is constructed,the coordinated planning of multi-node,multi-subnet and multi-frequency table resources realized,thus reducing overall planning difficulty of frequency resources and improving the efficiency of frequency planning.Finally,the question is theoretically answered that whether the frequency resources can be allocated for all subnets in the network topology under given frequency resources and constraints.
