Using the sequential procedures method for coordination of target functions of node control systems in MANET radio networks

Abstract

Analysis of the military experience of the Russian-Ukrainian war and the situation in the world as a whole indicate that information advantage is a determining condition for victory on the battlefield. To ensure advantage, a mobile, reliable and resilient information and communication network is necessary. A representative of such a network is a radio network of the MANET class, which has the ability to self-recover, self-organize and is able to function in conditions of limited resources and constant topology changes. For effective management of this complex system and ensuring the optimal level of operation of its nodes, coordination of target functions of control systems is important as a criterion by which the quality of the node and network operation is assessed. The article proposes a variant of applying the multi-criteria optimization method, namely the method of successive concessions in the process of coordinating target functions of nodal control systems in tactical mobile radio networks of the MANET class. The method is proposed to be used at the stage of forming the controlling influence of the coordinator node. The method of coordinating objective functions using fuzzy logic is taken as a basis, while the mobile network is considered as a complex hierarchical system. The key feature of using the method of successive concessions in this article is that a non-iterative version is used, which replaces the iterative process of determining the concession, which is necessary in classical methods of multi-criteria optimization. This allows you to reduce the time that the coordinator node spends on forming a fuzzy subset of admissible solutions and, as a result, the entire coordination process is accelerated. It is proposed to introduce typical scenarios of events in a mobile radio network, which will allow you to give priority to objective functions in accordance with each scenario. This will help prevent conflict situations in the network when objective functions contradict each other. The introduction of the method of successive concessions into the coordination process will allow you to obtain a clearer system objective function.
