摘　　要：针对无人机作战网络因自身内部故障或受到敌方攻击干扰而造成的网络性能下降及网络瘫痪问题,提出了一种基于功率分配的强韧性无人机作战网络拓扑构造方法。该方法首先以边连通度作为网络的韧性指标;其次,基于最大流最小割定理将最小割作为韧性指标的测度;在此基础上,考虑到单架无人机及系统整体功率有限,从物理层角度出发,通过调节无人机节点的发射功率以构造拓扑,从而提高网络韧性,提出了功率约束下的无人机作战网络功率分配策略;最后,采用粒子群优化算法解决功率约束下的拓扑结构韧性优化问题。仿真结果表明,在相同的调制方式及功率约束下,面对链路失效模式和节点失效模式,对比其它功率分配算法,基于粒子群优化算法得到的功率分配方案能有效提高无人机作战网络韧性,其所构建的网络在约66.7%的链路失效情况下,平均业务成功到达率仍保持在95%以上,满足实际作战需求。A topology construction method of the Unmanned combat network with strong toughness is proposed for the problem of network performance degradation and network paralysis caused by the failure of the Unmanned combat network itself or interference by enemy attack.The method first takes the edge-connectivity as the toughness indicator of the network;second,the minimum cut is used as the measure of the toughness indicator based on the maximum flow minimum cut(Max-flow min-cut)theorem,on the basis of which considering the limited power of a single UAV and the system,the topology is constructed by means of power allocation to improve the network toughness from the physical layer perspective,and the power allocation strategy of the Unmanned combat network under power constraint is proposed;finally,particle swarm optimization(PSO)algorithm is used to solve the topology toughness optimization problem under the power constraint.Simulation results show that under the same modulation and power constraints,the power allocation scheme based on the PSO algorithm can effectively improve the toughness of the Unmanned combat network compared with other power allocation algorithms in the face of link failure mode and node failure mode,and that the average successful service arrival rate of the constructed network remains above 95%in about 66.7%of link failures,which meets the actual combat requirements.
