摘　　要：由于参与节点多、移动性强,武器协同数据链一般采用分层的网络结构。战场环境下,己方通信经常会受到敌方干扰,而这将对武器协同数据链网络的一个很重要的性能指标——时延产生明显影响。另外,传统的只考虑下一跳延迟的路由方法并不能保证端到端延迟最小。针对这两个问题,提出了一种干扰环境下面向延迟的骨干节点路由方法和实现模型。该方法通过信息反馈、跨层的方法感知,利用临近节点的干扰信息和目的节点的端到端延迟信息,来为当前节点决定下一跳路由,实现最小端到端时延。仿真和数值结果表明,与几种典型路由协议相比,该方法具有更好的性能。The weapon cooperation data link adopts hierarchical methodology generally,as the nodes in it are numerous and moving rapidly. In the battlefield, the interference often occurs, and it will impact the delay seriously, which is an important parameter of the network. Moreover, the general approaches that only care about the delay of next hop can＇t always obtain the minim end-to-end delay. A delay oriented routing approach with implementing model was proposed for backbones. The SINR to the neighboring nodes and the end-to-end delay to the destination could be obtained to be used for deciding upon the next hop adopting the idea of feedback and cross-layer. The results provide important insights that the approach can get better performance than other several typical routing protocols.
