This book is about wireless local area networks (WLANs) based upon the IEEE 802.11 standards. It has three primary objectives: * To introduce the principles of 802.11 wireless networks and show how to con- ure equipment in order to implement various network solutions. * To provide an understandingof the security implicationsof wireless networks and demonstrate how vulnerabilities can be mitigated. * To introduce the underlying 802.11 protocols and build mathematical models in order to analyse performance in a WLAN environment. The book is aimed at industry professionals as well as undergraduate and gra- ate level students. It is intended as a companion for a university course on wireless networking. A practical approach is adopted in this book; examples are provided throughout, supported by detailed instructions. We cover a number of wireless vendors; namely, Cisco's Aironet, Alactel-Lucent's Omniaccess and Meru Networks. While separate vendors, all three systems have a Cisco IOS-like command-line interface. The GNU/Linux operating system is used extensively throughout this book.

Network Calculus is a mathematical theory concerned with deriving performance bound networks and this book aims to show that it can provide useful methods for designing and engineering networks. Examples are implemented in J making the subject more accessible to those that, although have a mathematical background, are not pure mathematicians.Basic and advanced concepts of J are introduced throughout when required to illustrate different issues. Topics covering Network Calculus include wide sense increasing functions, mini-plus algebra, convolution and arrival, departure and services curves. Comprehensive examples in the application of Network Calculus are given, models for simulating network traffic and network systems are discussed and congestion control is explored.This book brings Network Calculus closer to the network professional and will equally appeal to postgraduates studying network performance by providing valuable analytical tools and using J as a means of providing a practical treatment of the subject.
