ANALYSIS OF IEEE 802.11g WIRELESS CHANNEL MAXIMUN THROUGHPUT
Abstract:
Modern computer networks are realized in the form of heterogeneous systems consisting of wired and wireless segments. As one of the network performance characteristics maximum throughput of the communication channel is used. In wired communication channels as the maximum channel throughput used data rate in the physical channel. In wired communication channels this approach is correct. The difference between the data rate and the maximum channel throughput is less than a few percent.
Wireless links use much more sophisticated transmissions algorithms that have a large number of time pauses in the transmission and acknowledgment frames at the data link layer. Therefore the value of the data rate and the maximum channel throughput may differ significantly.
In this paper selection of a mathematical model for calculating the maximum throughput of 802.11 wireless channel, which is used in modern computer networks is carried out. On the basis of the proposed model maximum throughput of the 802.11g wireless channel for all mandatory data rates that are used in the standard were investigated. It is shown that for each data rate maximum throughput of the wireless channel can be calculated using the proposed mathematical model.
