The reliability improvement of TCP for the wireless packet data network by using the virtual TCP receive window

The "virtual TCP (Transport Control Protocol) receive window" scheme is proposed. In this scheme, the "general TCP receive window" in the TCP packet is replaced with the air link condition related "virtual TCP receive window" for TCP packets from MS (mobile station) to the Internet. Performance is evaluated for the cdma2000 network environment, and results show that the proposed scheme greatly improves the reliability of the TCP connection over the wireless packet data network.
