TCP Performance over UMTS / HSDPA Systems from Auerbach

Back Cover

Electrical Engineering

The evolution of the mobile communication market is causing a major increase in data traffic demands. This could lead to disrupted mobility and intermittent degraded channel conditions that contribute to poor transmission control protocol (TCP) performance. TCP Performance over UMTS-HSDPA Systems presents a comprehensive study of the effect of TCP on achieved application bit rate performance and system capacity, and shows how to reduce the interaction of wireless networks on TCP with minimal cost.

With self-contained chapters, the book consists of two main sections. The first several chapters provide background and describe the state of the art for wireless networks, emphasizing one of the third-generation (3G) wireless technologies: the universal mobile telecommunications system (UMTS). These chapters also include an analysis of the overall cell capacity of UMTS Release 99 and high-speed downlink packet access (HSDPA) systems. The second section focuses on the interaction of TCP with wireless systems, displaying mathematical modeling of the interaction of hybrid automatic repeat request (HARQ) and TCP in UMTS networks.

While offering information for advanced undergraduate students who are unfamiliar with code division multiple access (CDMA) wireless sytems as well as UMTS and HSDPA cellular systems, the book also provides extensive coverage of 'TCP over wireless systems' problems and solutions for researchers, developers and graduate students.

TCP Performance over UMTS-HSDPA Systems provides a comprehensive study of the effect of TCP both on achieved application bit rate performance and system capacity. The book describes how to reduce, with or without modification of TCP implementations, the effect of wireless networks on TCP. Emphasizing the effect of scheduling to improve TCP performance over wireless systems, the authors focus on the performance of TCP traffic over HSDPA. This text is ideal for advanced undergraduate students, graduate students, and researchers with basic knowledge in wireless networks that are keen on learning more about the UMTS access network evolution and interactions of the wireless link with TCP.
