TCP Performance over UMTS-HSDPA Systems provides a comprehensive study of the effect of TCP on both achieved application bit rate performance and system capacity. This book demonstrates how to reduce, without requiring any modification to TCP implemention, the effect of TCP on wireless networks, proposing a method to maintain a given application flow to reduce the effect with minimal cost. It pays particular attention to the interactions between TCP, ARQ, and scheduler when a shared channel is used the radio interface and not only between TCP and ARQ. The authors focus on the performance of TCP traffic over HSDPA. This text is ideal for researchers, advanced undergraduate students, and graduate students.
