Документ The method of improving the efficiency of routes selection in networks of connection with the possibility of self-organization(2019) Kuchuk, N. G.; Mohammed, A.; Shyshatskyi, A.; Nalapko, O.One of the directions improving the efficiency of communication networks with the ability to self-organization is the choice of rational route information transmission from sender to recipient. In the course of the analysis it was established that the existing scientific approaches for forecasting the state of the routes have high computational complexity, which prevents them from predicting the state of the transmission routes in real time. Therefore, the authors of this research conducted a methodology for forecasting the time overload of data transmission routes in mobile radio networks of radio networks with the possibility of self-organization. As the basic mathematical device, the neural network of Elman was used based on the calculation of the network neuron potential. The essence of the proposed method is to decide on the search for new routes based on the predicted time of overloading data transmission routes in mobile radio networks with the possibility of self-organization. The proposed method allows to predict the time of overloading of data transmission routes in mobile radio networks with the possibility of self-organization by reducing the computational complexity of the neural network and application of the algorithm for training the neural network. It is advisable to use the proposed methodology in radio communication with programmable architecture by developing appropriate software, which will increase the efficiency of choosing a route of data transmission in radio communication networks with the ability to self-organize.Документ Analysis of technical characteristics of the network with possibility to self-organization(Національний технічний університет "Харківський політехнічний інститут", 2018) Nalapko, O.; Shyshatskyi, A.At present, wireless technology is widely used in our everyday life and in military networks. In the sources, in the future, their percentage will only increase, according to an the analysis conducted. In this article, the analysis of technical characteristics and the classification of network routing protocols with the possibility of self-organization based on the main features of the organization and the mechanisms of the operation of the protocols. These mechanisms include the mechanism for updating route information, based on the method of storing route information, the topology of information organization and the use of protocols specific resources. The authors of the famous scientific papers in which the simulation was conducted do not fully describe the dependence of the influence of such criteria as the speed of the nodes, change of the network area, change of the number nodes in the network, change of the number of hops to the addressee to work routing protocols. The analysis of modern research directions in scientific editions and the tendencies of the development of routing protocols, analysis of routing protocols modeling data provided by the authors of the simulation was conducted. While the review of the simulation results, a description of the behavior of the protocols in different scenarios of modeling and commenting on the logic of the work of the protocols is carried out in accordance with the given classification, which subsequently makes it possible to determine the appropriate features of the protocols in accordance with the categories. Analysis of the advantages and disadvantages of network routing protocols with the ability to self-organization when changing the following criteria affecting the operation of protocols such as change the number of nodes in the network with the possibility of self-organization, the operation of protocols depending on the intensity of change in topology (speed of nodes), change the size of the area the network, which in turn also affects the number of nodes that redirect packets for delivery to the addressee. The dependence of the routing protocols on the use of higher level TCP and UDP protocols was also analyzed, where the coefficient of delivery of packets from the source to the addressee was analyzed. The main advantages and disadvantages of the main routing protocols of networks with possible self-organization that were considered by the authors of scientific works in modeling, such as AODV, DSDV, OLSR, and DSR, are highlighted. The definition of the actual and perspective direction of scientific work in further researches was conducted.
