摘　　要：由于建筑物或地形遮挡等因素,分布式地面战术移动点对点Ad-Hoc作战单元节点脱网时有发生,造成网络分裂,作战任务不能很好地遂行。为此,提出采用拓扑机器人来监视网络拓扑,拓扑机器人节点周期性发送拓扑探测消息收集网络拓扑状态,计算网络节点重要性,调整重要度最小的拓扑机器人节点,优化和重构当前拓扑,提高抗毁性。结合数值计算与网络仿真,验证拓扑机器人带来的网络抗毁性的提升。结果表明采取拓扑机器人来优化拓扑,可以有效地提高网络的抗毁性。Due to building or terrain shielding and other factors,node disconnections often occur in distributed ground tactical mobile Ad-Hoc combat units,resulting in network splitting,the combat mission can't be carried out well.Therefore,a new way of supervision of network topology based on topological robot was proposed,the topological robots periodically send topology detection messages to collect topology state,calculate the importance of nodes,the position of the topological robot with the least importance was actively adjusted to optimize and reconstruct the current network topology,thus improve the network invulnerability.The importance of network nodes was mainly measured from three aspects:network splitting influence,neighbor chain breaking influence and shortest path interruption influence.In order to measure the performance improvement brought by topological robot,the network aggregation index was used to measure the performance improvement brought by topology reconfiguration when the network hasn't been splitted.The repair ability of topological robot to topology split was presented by comparing the successful delivery rate of packets before and after topology reconstruction with network simulation.The simulation result show that adopting topological robots to optimize the topology of distributed ground tactical mobile Ad-Hoc combat units can effectively improve the invulnerability of the network.
