Abstract
The objective of the research is to develop information models in order to improve the efficiency of evaluating the parameters of the wireless channels in 802.11 standard. A feature of the information model of the wireless channel of 802.11 standard is an opportunity to evaluate the efficiency of transferring the information block taking into account the complete packet and frame transmission cycle in the event of errors in frames. In addition, the model accounts for the existence of other subscribers in the network and the mechanism of competition for the physical resource of the frequency channel. It has been established that channel efficiency is mostly affected by the presence of destabilizing factors in the channel, which lead to an increase in the number of service information and an increase in the transmission cycle due to the creation of reciprocal queries.
