Optimization of TCP/IP over 802.11 Wireless Networks in Home Environment

Internet connectivity today is based mainly on TCP/IP protocol suite. Performance of the Internet transport protocols may significantly degrade when end to end connection includes wireless links where packets delays and losses are caused by mobility handoffs and transmission errors. In this paper we perform analysis of the achievable throughput for different TCP versions, such as TCP Tahoe, TCP Reno, TCP New Reno, TCP Vegas and TCP SACK, in IEEE 802.11 wireless networks. The analysis showed the strong impact of Medium Access Control parameters, such as number of retransmissions and interface queue length in 802.11 networks on the obtained throughput.
