Abstract
We propose using the TCP decoupling approach to improve a TCP connection's goodput over wireless networks. The performance improvement can be analytic ally shown to be proportional to root MTU/HP_Sz, where MTU is the maximum t ransmission unit of participating wireless links and HP_Sz is the size of a packet containing only a TCP/IP header. For example, on a WaveLAN [32] wir eless network, where MTU is 1500 bytes and HP_Sz is 40 bytes, the achieved goodput improvement is about 350%. We present experimental results demonstr ating that TCP decoupling outperforms TCP reno and TCP SACK. These results confirm the analysis of root MTU/HP_Sz performance improvement.
