Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
QoS is an important component of any operation, but it is particularly important in wireless transmission systems. To improve network strength and data transmission, we need to use a network that can provide the most benefits to its end users. This paper detail simulates the CSMA/CA protocol in DCF mode without using virtual channel sensing (i.e., RTS/CTS frames). In this article, a comparison of the performance of an IEEE 802.11e network is made, and the results are compared to improve the network's efficiency.
