THE ASSESS THE FAULT-TOLERANCE, EFFİCİENCY AND PERFORMANCE OF MİLİTARY FİELD LOCAL NETWORK TOPOLOGY

Abstract

Depending on the location of communication nodes of the control points and points of relay in the field, especially in mountainous areas, finding line of sight (LOS) and establishing a good radio relay connection can be challenging. In addition, depending on the requirements for bandwidth and communication stability, in the field, a situation often arises where it is possible to build a network only based on certain types of topologies. To assess the security of military field telecommunication networks, it is important to determine such important parameters as network stability or fault-tolerance, efficiency, transmission capacity and delay time. It is known that the greatest values of these parameters are achieved in the type of "fully connected" network topology. However, low efficiency, high power consumption, difficulties in safely and hidden placement of a large number of vehicles in the battle area and the complexity of maintenance, as well as the fact that radio relay hardware vehicles consist mainly of 2 sets of radio relay devices make this type of topology unsuitable for field networks. Therefore, it is important to define a network topology with high stability, using the minimum amount of radio relay vehicles. For the above reason, the article proposes mathematical methods for calculating the fault tolerance and efficiency of the selected network topology, as well as fault tolerance, bandwidth and latency for each network node.
