摘要：A transport layer protocol such as TCP has been designed for fixed networks with fixed end-systems. Data transmission takes place using network adapters, fiber optics, copper wires, special hardware for routers etc. This hardware typically works without introducing transmission errors. TCP will work perfectly for wired networks. To support mobility TCP require some enhancements However, one cannot change TCP completely just to support mobile users or wireless links but every enhancement to TCP has to remain compatible with the standard TCP. This paper gives overview of classical enhancements to TCP for mobility by using various approaches i.e. Indirect TCP, Snooping TCP, Mobile TCP, Fast retransmit/fast recovery, Transmission/time-out freezing Selective retransmission, Transaction-oriented TCP.
