TCP has variable congestion control schemes used both in wired and wireless network, such as Cubic, Reno, Vegas, Westwood and WinSock. As most cellular systems have already migrated to 3G and 4G is emerging from the horizon, it would be meaningful to know which scheme performs the best in 4G wireless network. This thesis aims at testing TCP communication performance by using different congestion control schemes in 4G system and helping mobile industries and application developers to select a correct scheme. Different FTP methods were used. In total, 1200 samples were collected by network monitors. They are analyzed and processed using Microsoft Excel. The statistics analysis results indicate that WinSock scheme performs the best in the case of downlink and Westwood behaves the best when the network condition is not good.
