The Comparison of Various Configurations of Intragroup Exchange Network with Cluster Structure

The paper is devoted to comparison of various configurations of intragroup information exchange network with cluster structure. The clusters are considered to be fully connected networks. The aim of the paper is to find out the best network configuration for a given conditions. In the paper the estimates of data transfer rate are obtained analytically and network bit error rate is estimated for various cluster configurations on the basis of fully connected network simulation results. From the results it follows, that for greater reliability of data transfer in the case of slightly spaced clusters a network should be configured to small number of big clusters, which communicate through point-to-point channel. In the case of clusters at a big distance for greater data reliability it is preferable to configure network to big number of small clusters, which communicate as a fully connected network. In the case of higher transfer rate priority a network should be configured to big number of small clusters, which communicate through point- to-point channel.
