发布时间：2019-01-19 20:07
【摘要】：战术通信网是战场指挥控制系统的重要组成部分。通过网络仿真的方法研究网络性能和网络协议,不仅降低研发成本,而且能够为构建高效的战术指挥控制系统提供重要的参考依据。在实际情况下,战术通信网需要通过不同子网之间的协作来实现特定的战术目标。通过网络仿真软件进行研究虽然简单高效,但是已有节点模型、时隙分配算法以及网络结构模型已无法满足需求,需要结合战术通信网的实际需求重新设计。文中将大规模军用Ad Hoc网络仿真模型的研究与实现分为了两个阶段:局域战术通信网和大规模军用Ad Hoc战术通信网。局域战术通信网由单个子网组成,该阶分析了目前已有的几种时隙分配算法,结合战术通信网的实际需求和节点生成报文的特性提出了一种符合马尔科夫过程的混合时隙分配算法。大规模军用Ad Hoc战术通信网将网络的节点分为簇首节点和簇成员节点,将成员节点模型的搭建分为了两个部分。第一部分,设计了一种具有TDMA时隙分配方式和应用层收发包功能的簇成员节点模型,并由该模型和仿真软件中提供的路由节点模型搭建了具有路由转发功能的局域战术通信网,分析了不同远近程度的报文对战术通信网端到端延迟的影响。第二部分,设计了一种具有应用层收发包功能的簇首节点,结合簇成员模型,将大规模通信网分为了旅、营、连和车四个层次,针对这四级节点的报文数量特征提出了一种按比例分配时隙的算法。在OPNET仿真软件中分别对这两个阶段进行了建模仿真,收集了不同报文长度下三种通信网的端到端延迟。仿真结果表明采用混合时隙分配算法的局域战术通信网在端到端延迟方面相对于采用固定时隙分配算法有明显的提高。在具有路由转发功能的局域战术通信网中设计了簇成员节点模型,在仿真过程中随着报文长度和报文目的地址的变化所收集到的端到端延迟与理论计算值相符,有较好的可行性。采用分层结构的大规模军用Ad Hoc战术通信网中,簇首节点模型和簇成员节点模型都具有主动收发包功能,其仿真结果与实际计算数据相比误差在允许范围内,说明搭建的仿真模型及仿真系统有较高的置信度。
[Abstract]:Tactical communication network is an important part of battlefield command and control system. The research of network performance and network protocol through network simulation can not only reduce the cost of research and development, but also provide an important reference for the construction of an efficient tactical command and control system. In practice, tactical communication networks need to achieve specific tactical objectives through cooperation among different subnets. Although the research on network simulation software is simple and efficient, the existing node model, slot allocation algorithm and network structure model can not meet the requirements, which need to be redesigned in combination with the actual demand of tactical communication network. In this paper, the simulation model of large-scale military Ad Hoc network is divided into two stages: local tactical communication network and large-scale military Ad Hoc tactical communication network. The local tactical communication network is composed of a single subnet. In this order, several existing slot allocation algorithms are analyzed. According to the actual requirements of tactical communication network and the characteristics of node generating packets, a hybrid slot allocation algorithm is proposed, which accords with Markov process. The large-scale military Ad Hoc tactical communication network divides the nodes of the network into cluster head node and cluster member node, and the member node model is divided into two parts. In the first part, a cluster member node model with the function of TDMA slot allocation and application layer packet sending and receiving is designed, and a local tactical communication network with routing and forwarding function is built by the model and the routing node model provided in the simulation software. The effects of different degrees of packets on the end-to-end delay of tactical communication networks are analyzed. In the second part, a cluster head node with the function of sending and receiving packets in the application layer is designed. Combined with the cluster member model, the large-scale communication network is divided into four levels: brigade, battalion, company and vehicle. In this paper, an algorithm of proportional allocation of time slots is proposed for the quantitative features of the four-level nodes. In the OPNET simulation software, the two stages are modeled and simulated, and the end-to-end delay of three communication networks with different message length is collected. The simulation results show that the end-to-end delay of the local tactical communication network using hybrid slot allocation algorithm is significantly higher than that of the fixed slot allocation algorithm. In the local tactical communication network with routing and forwarding function, a cluster member node model is designed. The end-to-end delay collected in the simulation process is consistent with the theoretical calculation value with the change of the packet length and the destination address of the packet. There is good feasibility. In the large-scale military Ad Hoc tactical communication network with hierarchical structure, both the cluster head node model and the cluster member node model have the function of active receiving and sending packets. The simulation results are within the allowable range compared with the actual calculated data. It shows that the simulation model and simulation system have high confidence.
