Performance evaluation of traditional TCP variants in wireless multihop networks

TCP-Transmission Control Protocol is a connection oriented and reliable process-to-process communication at the transport layer of TCP/IP model. TCP ensures stream communication with the end-to-end flow control, error control and congestion control. Years ago, TCP was introduced to work with the wired networks where the cause of losses is mainly the network congestion. In recent years, wireless networking is becoming more and more popular. A significant amount of performance degradation is found when traditional TCP variants are used with the wireless networks. Wireless networks are more vulnerable to the losses because of the inherent impairments of wireless communication. This paper surveys various TCP variants with wireless multi-hop networks. Simulation is carried out with NS 2.35.
