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.

This practically-oriented textbook provides a clear introduction to the different component parts of an operating system and how these work together. The easy-to-follow text covers the bootloader, kernel, filesystem, shared libraries, start-up scripts, configuration files and system utilities. The procedure for building each component is described in detail, guiding the reader through the process of creating a fully functional GNU/Linux embedded OS. Features: presents a concise overview of the GNU/Linux system, and a detailed review of GNU/Linux filesystems; describes how to build an embedded system to run on a virtual machine, and to run natively on an actual processor; introduces the concept of the compiler toolchain, demonstrating how to develop a cross toolchain so that programs can be built on a range of different architectures; discusses the ARM-based platforms BeagleBone and Raspberry Pi; explains how to build OpenWRT firmware images for OMxP Open-mesh devices and the Dragino MS14 series.

This easy-to- follow textbook/reference guides the reader through the creation of a fully functional embedded operating system, from its source code, in order to develop a deeper understanding of each component and how they work together. The text describes in detail the procedure for building the bootloader, kernel, filesystem, shared libraries, start-up scripts, configuration files and system utilities, to produce a GNU/Linux operating system. This fully updated second edition also includes new material on virtual machine technologies such as VirtualBox, Vagrant and the Linux container system Docker.Topics and features: presents an overview of the GNU/Linux system, introducing the components of the system, and covering aspects of process management, input/output and environment; discusses containers and the underlying kernel technology upon which they are based; provides a detailed examination of the GNU/Linux filesystem; explains how to build an embedded system under a virtual machine, and how to build an embedded system to run natively on an actual processor;introduces the concept of the compiler toolchain, and reviews the platforms BeagleBone and Raspberry Pi; describes how to build firmware images for devices running the Openwrt operating system.The hands-on nature and clearly structured approach of this textbook will appeal strongly to practically minded undergraduate and graduate level students, as well as to industry professionals involved in this area.
