TCP is one of the main protocols that govern the Internet traffic nowadays. However, it suffers significantperformance degradation over wireless links. Since wireless networks are leading the communicationtechnologies recently, it is imperative to introduce effective solutions for the TCP congestion controlmechanisms over such networks. In this research four End-to-End TCP implementations are discussed,they are TCP Westwood, Hybla, Highspeed, and NewReno. The performance of these variants is com
