A Survey of TCP Performance in Wireless Network

Because the standard TCP can not distinguish the nature of packet loss, TCP performance over three kinds wireless networks （cellular network, ad hoc network and satellite network） will be deteriorated very much by invoking congestion control incorrectly if standard TCP is directly applied on the wireless networks. Factors that affect TCP performance of the three kinds wireless networks are analyzed, and additional technologies that should be added to the standard TCP to alleviate negative influences are pointed out. Some methods of improving TCP performance of wireless network are discussed, and comparison and classification are carried out. Research directions of TCP performance over wireless network are also discussed.
