Development algorithmic support for the synthesis of topological structures of communication systems

The paper shows that one of the problem of telecommunication systems is indeterminacy of relation of a system's element to a particular subsystem of informational network, when the element could be used either as a user equipment or a management subsystem. The result is the difficulty of reintroduction of ad hoc networks into the structure of the mobile communication systems. To solve this problem a method of describing the structure of information communications has been developed. The method is based on the presentation of the system as a single logical structure. The base of the structure are virtual nodes. A set of virtual nodes forms a virtual network. The capacity of a virtual network varies according to the laws of probability. Probability laws are determined on the basis of statistics of virtual host attendance by physical nodes. The sphere of application of communications systems is the improvement of management efficiency due to anticipating alternative routes of data transmission and different standards of communication systems synthesis. The results can be used to study the interactions of social and economic systems of the region. To demonstrate the results the experiment on the prediction of the number of physical nodes in a given virtual host has been carried out. The probability of occurrence of physical objects in the virtual site has been calculated on the bases of the obtained data. The calculation results enable us to construct a map of the area attendance by physical nodes and to calculate traffic routes between virtual hosts.
