摘要：

Nowadays, the scale and complexity of military communication network are increasing, so a high availability network is urgently needed to meet the needs of users for high reliability services, and the quantitative study of network availability is of great significance to evaluate the reliability of tactical ad hoc network. For the mobile model and fault characteristics of tactical ad hoc network, a network availability model based on Markov chain is established, the delay model of the main factors affecting network service is studied by analyzing the CSMA/CA transmission mechanism. On the basis of the proposed model, the statistical principle is used to propose a fault-based quantitative evaluation model of service availability of mobile ad hoc network. And taking a typical combat communication network of an army unit as an example, the relationship between network availability and core indexes such as number of nodes, transmission rate and message length is analyzed, and the effectiveness of the analyzed results is verified by simulation. © 2021, Editorial Board of Acta Armamentarii.
