TCP, RTT, Mobility
Terminal mobility is a critical factor that affects trans mission control protocol (TCP) performance in the wire less network. This paper quantifies the impact of terminal mobility on the performance of TCP congestion control mechanism in wireless networks. TCP performance is studied in fixed wired, fixed wireless and mobile wireless network environments using experimentation and simu lation techniques. Packet delay performance is determined by experimentation. Simulations are then performed to predict throughput, packet loss, round-trip-time and re transmission timer settings. Our analysis shows that ter minal mobility increases packet delay and delay variation, and also degrades throughput performance of TCP con nections in wireless environments.
