Simulation analysis of TCP performance on IEEE 802.11 wireless LAN

The TCP protocol is the most frequently used transport layer protocol in the Internet, and it is originally designed, improved and tuned to work efficiently on wired network where the packet loss is very small. When packet loss is detected, TCP will trigger the congestion recovery algorithms. While in the wireless environment, the bit error rate of a wireless link is much higher and a wireless connection might be temporally broken not only for the reason of congestion but also due to temporal link impairment such as shadowing effect or buffer overflow. So, it is valuable to research the current versions of the TCP performance over a wireless environment. Wireless local area networks (WLAN) provide users with high-speed wireless data access to the network and voice capabilities for telephone conversations. We focus on the simulation analysis of the TCP performance over the DCF access mode of IEEE 802.11 WLAN
