dc.description.abstract TCP optimization for wireless networks to deal with packet losses due to fading, shadowing and contention should preferably maintain TCP end-to-end semantics with minimal dependence on intermediate nodes. The development of advanced 3G networks and services makes it necessary to find a way of improving TCP's efficiency and resource utilization. Previous research on this issue suggests that TCP needs radio network feedback to distinguish wireless related losses from congestion related losses. This paper presents such a mechanism that notifies the TCP sender of any noncongestion related losses by introducing a proxy at the RNC node of the UMTS network. Only a minimal change to the standard TCP is required to achieve this. OPNET is used in this study and the simulation results show that the proposed scheme significantly improves the TCP performance en_AU
