It has been constructed with the support of many researchers around the world, working on resource allocation, quality of service and WiMAX applications. Such many different works on WiMAX, show the great worldwide importance of WiMAX as a wireless broadband access technology. This book is intended for readers interested in resource allocation and quality of service in wireless environments, which is known to be a complex problem. All chapters include both theoretical and technical information, which provides an in depth review of the most recent advances in the field for engineers and researchers, and other readers interested in WiMAX. In the first section, readers will find chapters on resource allocation techniques, such as scheduling, call admission control, frequency reuse and cross-layer techniques. The second section presents the evaluation of various models for ensuring the QoS for applications running on WiMAX networks. Finally in the third section, applications for WiMAX are presented, with wireless mesh networks based on multi-hop and relay architectures. Roberto C. Hincapie, PhD & Javier E.
