Delays models of measurement and control data transmission network

Abstract

The paper herein aims at analysing one of the parameters characterising data transmission network. This parameter is transmission delay. The first part of the article presents the concept of teletransmission system delay model construction with reference to all sources of delays generated during data transmission between a source and target. This model also includes the network proxy devices which play a significant role in the total amount of delays. In the following part of this paper the analysis of transmission delays has been described with the use of probabilistic model. It has been supported with simulation examples. For this reason, the experimental transmission system was built which was based on ZigBee wireless standard. There were experiments made in different propagation conditions on the basis of which the assumed model has been verified.
