Transmission control protocol is a reliable, connection oriented, congestion control protocol used by most of the networks. Significance of TCP is the congestion control mechanism that controls TCP sending rate and makes TCP react to congestion signals. Variety of TCP variants is available to suite to the requirements of various networks. TCP is a transport layer protocol that ensures ordered delivery...
Wireless channel condition varies due to factors like fading, path loss, noise and other channel impairments. Due to these the channel throughput, packet delivery ratio also varies. In order to achieve higher transmission rates, various modulation schemes are in use. Adapting suitable modulation scheme to match the transmission rates to time varying channel conditions can increase the throughput of...
In wireless communication networks link adaptation techniques are widely used to improve the quality by adapting various parameters of channel. Adaptive modulation and coding (AMC) is one such technique which adopts various modulation techniques based on certain channel conditions like received signal power or signal strength or distance. This paper compares simulation results of adaptive modulation...
