Hura V. Improving the management quality of telecommunication systems on the basis of updating of network protocols

Object of study is telecommunication network on the basis of ІЕЕE 802.11 protocol. In order to develop methods for increasing the capacity, noise immunity, quality of transmission and reliability of operation of discrete messages transmission system in radio channels with constant, variable and random parameters the analytical model of local wireless network is determined being based on the use of ІЕЕE 802.11 protocol. The model allows to estimate the efficiency during the optional loading mode, takes into account all features of this protocol in an ideal channel. The modification of the model allows to take into account the influence of radio noises and to analyze the wireless network with heterogeneous stations. The analytical WLM that takes into account interference of stations in this network is defined. Based on the mentioned analytical methods and simulation technique the comparative numerical estimation of ІЕЕE 802.11 protocol is made. In addition the estimation of main indices of the efficiency of wireless local networks is carried out; the efficiency of the operation of different mechanisms of the ІЕЕE 802.11 protocol is analyzed. Obtained optimization algorithms of basic parameters of the protocol could be the basis for the development of the system for the automatic setup of the protocol parameters that enable to obtain an optimum indices. An application domain is the system of telecommunications.
