Learn how to provide seamless, high quality multimedia for the
wireless Internet
This book introduces the promising protocols for multimedia
services and presents the analytical frameworks for measuring their
performance in wireless networks. Furthermore, the book shows how
to fine-tune the parameters for Quality of Service (Qo S)
provisioning in order to illustrate the effect that Qo S has upon
the stability, integrity and growth of next generation wireless
Internet. In addition, the authors provide the tools required to
implement this understanding. These tools are particularly useful
for design and engineering network architecture and protocols for
future wireless Internet. Additionally, the book provides a good
overview of wireless networks, while also appealing to network
researchers and engineers.
Key Features:
* Provides a comprehensive and analytical understanding of the
performance of multimedia services in wireless Internet, and the
tools to implement such an understanding
* Addresses issues such as IEEE 802.11, AIMD/RED (Additive
Increase-Multiplicative Decrease/ Random Early Detection),
multimedia traffic models, congestion control and random access
networks
* Investigates the impact of wireless characteristics on Qo S
constraint multimedia applications
* Includes a case study on AIMD for multimedia playback
applications
* Features numerous examples, suggested reading and review
questions for each chapter
This book is an invaluable resource for postgraduate students
undertaking courses in wireless networks and multimedia services,
students studying advanced graduate courses in electrical
engineering and computer science, and researchers and engineers in
the field of wireless networks.
