Increasing data transmission rate technique in an aerial radio communication network for control of aircrafts through the adaptive frequency-time network resource distribution taking into account the transmitted teletraffic intensity
Relevance. The intensity of the use of the Russian Air Force increased significantly at the beginning of the XXI century. At the same time, problematic technical aspects of the operation and management of combat aircraft began to be identified more often. One of these aspects is the discrepancy between the high requirements for operational control of a combat aircraft and the truly timely teletraffic (commands and data on the air situation) transmission on an aircraft board. Preliminary studies have shown that when transmitting teletraffic, changes in the of transmitted teletraffic intensity on various flight stages and the gist of aircraft tasks are not taken into account. This leads to a decrease of the teletraffic timeliness and, as a result, to a decrease in the efficiency of combat aircraft control. The goal of the article is to develop the increasing data transmission rate technique in an aerial radio communication network for control of aircrafts through the adaptive frequency-time network resource distribution taking into account the transmitted teletraffic intensity. Novelty. The novelty elements of the presented technique are to add new operations implementing two-stage distribution of network resources. At the first stage, a temporary network resource is distributed due to an adaptive change in the capture pause of a multiple access channel in the aerial network. At the second stage, a frequency network resource is distributed if the total requirements for the speeds of all aircraft control channels cannot be provided with the distribution of the temporary network resource. At the same time, the adaptive distribution of the time-frequency resource of the aerial network is based on forecast of the traffic intensity transmitted through the aircraft control channels. The practical significance of the article lies in the fact that the developed technique can be used to increase efficiency of combat aircraft control when aircraft is pointing at an aerial target.
