Bandwidth increasing the of a united aerospace communications network. Part 1. Models and method of bandwidth increasing of the united network with used Mesh-technologies
Problem statement: The Aerospace forces of Russia are used to solve the special military tasks in abroad, where global controlling of aircraft is not always possible. The global control of aircraft can be achieved by coupling the air radio communication networks (ARCN) for aviation control through the satellite communication systems (SatComm) due to SatComm provide global coverage over the entire territory of the Earth. At the same time, such coupling needs the solution some technological tasks, such as: the coordination of data exchange rates, the development of network protocols for the joint functioning of ARCN and SatComm, the development of routing protocols, as well as the ways for high bandwidth of air and space radio networks. The aim of this paper is to increase the capacity of the Joint AeroSpace Communications Network (JASCN) for aviation control through the development of models and a method of decentralized routing of information flows in air and space subnetworks of JASCN. Novelty. Elements of the models novelty are to review of JASCN as a multi-level system, the core of which is a SatComm, and the lower level is formed by several ARCNs, as well as take into account using of Mesh technology specifics in ARCN when a model of decentralized routing is formed. Elements of the method novelty are the joint consideration of both air radio subnetworks specifics, as well as used of the Newton method to obtain a solution for balancing and routing traffic in JASCN. Results of the study are the model of JASCN with hierarchical routing of information flows through the SatComm; the model of JASCN with decentralized routing of information flows through the SatComm and adjacent ARCNs, which is based on Mesh technology; the method for distributing of information flows through the air and space subnetworks of JASCN. Practical significance: using of models and techniques, which are developed in this study, allows achieving high bandwidth of JASCN and global control for aircraft of the Russian Aerospace Forces.
