摘　　要：为进一步完善常规方法构建的微波接力网组网拓扑,提出了一种基于最优链路集的网络节点再优化方法。该方法综合考虑节点吸引系数、链路衰落概率、节点通信冗余等因素,借助网络拓扑优化的思想,采用遗传算法构造了微波接力网的最优链路集;以节点在该集合中的度为依据,通过对节点的合理排序,以部分用户节点代替非必要的干线节点,完善了组网拓扑。在修改链路和节点价值集后,该方法还可解决其他网络干线、中继节点的选择问题。The microwave relay network nodes are studied and the topology is optimized.Considering the link attenuation probability,node attraction coefficient and communication redundancy,the optimal link set is obtained by genetic algorithm with the idea of network topology optimization.By calculating the degree of each node in the optimal link set and sorting the node with the value of degree,the candidates of the trunk nodes are given.The microwave relay network topology given by the conventional method is optimized.The method has certain versatility.It can be applied to the selection of other network trunks and relay nodes by modifying the link and node attribute set.
