Conference article

This paper continues the study, presented at the 8th EUROSIM Congress on Modeling and Simulation and devoted to creation of algorithm and simulation model of network functioning, taking into account dynamic characteristics of the network in condition of variable relationship signal-to-noise. Simulation algorithm was augmented for adequately representation of the state of the real network i.e. possible changes of topology due to the link failures and disabling individual nodes. It is possible to expand the capabilities of the model presented in the 8th Congress as a simulation model of Information Flow on Transport Layer of Open System Interconnection Model. The current version of the model realizes input of the adjacency matrix describing the network topology, the algorithm of the path search by Dijkstra on the network level, and simulation of the loss of connection. So the main goal of the new paper is to bring the structure of the model to the structure of the real network and to check the possibility of transferring a given amount of information in conditions of interference by means of evaluation of coefficient of readiness for Data Communication System.
