Learn how to provide seamless, high quality multimedia for thewireless Internet
This book introduces the promising protocols for multimediaservices and presents the analytical frameworks for measuring theirperformance in wireless networks. Furthermore, the book shows howto fine-tune the parameters for Quality of Service (QoS)provisioning in order to illustrate the effect that QoS has uponthe stability, integrity and growth of next generation wirelessInternet. In addition, the authors provide the tools required toimplement this understanding. These tools are particularly usefulfor design and engineering network architecture and protocols forfuture wireless Internet. Additionally, the book provides a goodoverview of wireless networks, while also appealing to networkresearchers and engineers.
Key Features:
* Provides a comprehensive and analytical understanding of theperformance of multimedia services in wireless Internet, and thetools to implement such an understanding
* Addresses issues such as IEEE 802.11, AIMD/RED (AdditiveIncrease-Multiplicative Decrease/ Random Early Detection),multimedia traffic models, congestion control and random accessnetworks
* Investigates the impact of wireless characteristics on QoSconstraint multimedia applications
* Includes a case study on AIMD for multimedia playbackapplications
* Features numerous examples, suggested reading and reviewquestions for each chapter
This book is an invaluable resource for postgraduate studentsundertaking courses in wireless networks and multimedia services,students studying advanced graduate courses in electricalengineering and computer science, and researchers and engineers inthe field of wireless networks.
