Distributed Network Data
Build your own distributed sensor network to collect, analyze, and visualize real-time data about our human environment - including noise level, temperature, and people flow. With this hands-on book, you'll learn how to turn your project idea into working hardware, using the easy-to-learn Arduino microcontroller and off-the-shelf sensors.

Authors Alasdair Allan and Kipp Bradford walk you through the entire process, from prototyping a simple sensor node to performing real-time analysis on data captured by a deployed multi-sensor network. more »
Packet Guide to Voice over IP
Go under the hood of an operating Voice over IP network, and build your knowledge of the protocols and architectures used by this Internet telephony technology. With this concise guide, you'll learn about services involved in VoIP and get a first-hand view of network data packets from the time the phones boot through calls and subsequent connection teardown.

With packet captures available on the companion website, this book is ideal whether you're an instructor, student, or professional looking to boost your skill set. Each chapter includes a set of review questions, as well as practical, hands-on lab exercises. more »
Zenoss Core 3.x Network and System Monitoring
Zenoss Core is an enterprise-level systems and network monitoring solution that can be as complex as you need it to be. And while just about anyone can install it, turn it on, and monitor "something", Zenoss Core has a complicated interface packed with features. The interface has been drastically improved over version 2, but it's still not the type of software you can use intuitively - in other words, a bit of guidance is in order.

For system administrators, network engineers, and security analysts, it is essential to keep a track of network traffic. more »
FreeRADIUS
The Open Source pioneers have proved during the past few decades that their code and projects can indeed be more solid and popular than commercial alternatives. With data networks always expanding in size and complexity FreeRADIUS is at the forefront of controlling access to and tracking network usage. Although many vendors have tried to produce better products, FreeRADIUS has proved over time why it is the champion RADIUS server. This book will reveal everything you need to know to get started with using FreeRADIUS. more »
iOS Sensor Apps with Arduino
Turn your iPhone or iPad into the hub of a distributed sensor network with the help of an Arduino microcontroller. With this concise guide, you'll learn how to connect an external sensor to an iOS device and have them talk to each other through Arduino. You'll also build an iOS application that will parse the sensor values it receives and plot the resulting measurements, all in real-time.

iOS processes data from its own onboard sensors, and now you can extend its reach with this simple, low-cost project. If you're an Objective-C programmer who likes to experiment, this book explains the basics of Arduino and other hardware components you need - and lets you have fun in the process. more »
