TCP/IP header compression: proposal and performance investigation on a WCDMA air interface

Two TCP/IP header compression (HC) schemes for wireless networks are proposed and investigated on a WCDMA air interface. These novel schemes are compared with the classical ones by means of a TCP/IP New Reno simulator taking as input WCDMA channel traces. These channel traces are derived by using a simulator built according to the UMTS standard requirements. The RLC (radio link control) level operates in transparent mode, while overhead is added to simulate the presence of a MAC level. Some new performance metrics are introduced to evaluate the performance of HC schemes.
