Wireless Local Area Network (LAN) and Bluetooth are two phenomena in wireless networks. They have become very successful in the current market and are deployed in many different environments. However, there are still many unresolved issues such as Mobility Management support, Quality of Service (QoS) support, etc. The primary focus of this book is to present these two hot and rapidly evolving areas as well as issues and solutions involved with them. It is this realisation that has motivated the editing of this book. The goal of the book is to serve as a reference for wireless LAN and Bluetooth. In this book, the authors review important developments and new strategies for these topics. Important features and limitations of methods and models are identified. Consequently, this book can serve as a useful reference for researchers, educators, graduate students, as well as practitioners in the field of wireless networks.
