摘要: 针对MANET组网模式下的战术无线通信网络,节点可灵活自组,通信方式多样化,但经多跳转发的传输链路易受干扰影响而导致整体路径失效,受干扰威胁较大的问题,除采用一系列物理链路级传统抗干扰手段外,还应通过控制和优化拓扑结构,提高干扰下通信系统对节点和链路失效的容忍度和网络性能恢复能力,这也是提高路由等上层协议的可用性和生存能力的基础。以复杂系统理论为指导,在图论和随机过程理论的基础上分析不同通信环境条件变化对干扰阻塞状态的影响,判别节点重要度和网络概率连通性,提出了一种基于局部稳定性测度的拓扑优化方法,用于构造高可靠网络。通过仿真实验分析,验证了该方法的有效性,可提高实际动态传播条件下的军用通信网络的抗干扰能力和自优化能力。

Abstract: The military wireless communication network based on MANET architecture is characterized by a variety of communication modes and flexible self-organizations of nodes, but the multi-hop wireless transmission links are vulnerable to interference. In addition to using a series of traditional anti-jamming technologies at physical and link layers, the control and optimization means of network topology for getting better invulnerability and survivability become key issues in the research of anti-jamming policy of network layer. In dynamic electromagnetic interference environment, the tolerance of node or link failures is the basis of improving the survivability of the upper layer protocols, as well as the network recovery capability. According to the complex system theory, graph theory and random process theory, the influence of dynamic communication condition in battlefield is analyzed, and then a topology optimization method based on the measures of local stability is proposed in view of the importance of nodes and the connectivity of topology in order to construct a more reliable network. Simulated results show that the proposed method provides satisfactory efficiency and can improve the anti-jamming and self-optimizing performances of military communication networks under dynamic transmission.
