This book quickly pinpoints trouble spots that any average PC user may run into. The author's personal style of solving a problem makes the text very user-friendly. For example, I occasionally am most annoyed by suddenly having my re-typing of a word deleting others. I found this problem solved in Section #45== "You may be tapping on a key without realizing you are executing a command--it's like chewing on a pencil or drumming your fingers. I had pressed a key unknowingly and each subsequent word I type deletes the previous one. Very annoying! One day I pressed the Shift Key five times, and a window popped up." In the text is a view of this window "Sticky Keys" and the author notes-- "Just click on the Go to the Ease of Access Center to disable the keyboard shortcut."
Many other examples like this are clearly and briefly given, so that the title of the text is apt! I haven't gotten to the last sections, about adding memory or changing the hard drive, but the author gives good illustrations and makes it sound easy, even for me, an amateur stay-at-home tech person. The Table of Contents lets a reader zoom directly to whatever problem has reared its ugly head, and the illustrations are very helpful. Probably a person who is experienced with computers wouldn't find much new in this book, but for newbies like me, it's most useful.

Ambient Networks: Co-operative Mobile Networking for the Wireless World Review

Ambient Networks: Co-operative Mobile Networking for the Wireless World
Average Reviews:

(More customer reviews)
Ambient Networks aim at providing network integration through a new kind of network architecture. Ambient Networks go beyond current convergence approaches that integrate specific technologies, by providing a unified networking concept that can adapt to as many possible environments (radio technologies, services, devices).
The content of the book reflects well the status of this topic: it's only in the prospective stage. The challenges are so hige that it's unclear today how fast developments will be made in this area. On the other hand, ambient network thinking makes us think about what kind of network usability and seamlessness one would like to see in the long-term future.
The central concept of Ambient Networks is "network composition". Network composition refers to the techniques that allow the control spaces of different networks to be dynamically and recursively combined to support complex scenarios. Network composition requires co-operation, negociation, and proper interfaces to be defined across networks and layers of the network stack, hence constitutes a tremendous challenge compared to today's networks.
The book starts by presenting the current communications environment and the central concept in ambient networking: network composition. The motivation for ambient networks, convergence, is discussed in chapter 2. Convergence towards all-IP networks is an opportunity to go further than simply allowing some technologies (GSM, IMS, WiMAX, wireless LAN,...) to interact. The third chapter presents the business environment of Ambient Networks: is there a business future for such dynamic networks? The foreseen architecture and principles of Ambient Networks is presented in chapter 4. Security in an heterogeneous environment like Ambient Networks faces big challenges: identification and authentification of mobile nodes, authorization to dynamically composed services. The conceptual aspects of network composition are addressed in chapter 6: how might composition procedures work, how to define the types of composition? Chapter 7 describes the Generic Ambient Networks Signalling (GANS), the signalling framework between functional elements of Ambient Networks. The problems faced by multi-radio access are tackled in chapter 8: advertising services and networks, access selection, authentication, payment, etc. An evaluation of the potential gain of using several radio access technologies at once is also presented to illustrate the potential of network composition across different technologies. Mobility management is dicusssed in chapter 9. Managing address space when physical locations change over time, for different kinds of devices using different sets of access technologies is challenging. Locators of nodes and bootstrapping requires new ways of thinking about routing and address space. Mobility in an heterogenous environment makes handover operations even more complex. Making name resolution maintain end-points communication in a mobile and heterogeneous environment requires more than the traditional DNS. For proper delivery of different media, overlay networks are envisioned as a solution in chapter 10. A possible solution for the collection, dissemination and management of network context called ContextWare is discussed in chapter 11. Finally, chapter 12 discusses the different approaches to Ambient Networks management and details one possible example (P2P).

This book is a must for anyone just entering the cellular telecommunications field or who just wants to fine tune his knowledge. The author definitely understands the ins-and-outs of this ever so changing field. He presents a down to earth comparison of mankinds technological advances to nature, which was superb. He gives a general explanation of essential aspects of cellular communications and then dedicates a chapter to each to further expand on the same. He keeps the explanations to a level that is understandable to a person with no technical background but yet instructional for any engineer or computer programmer. His presentation is analytical and systematic but not boring. This book is a great technical reference guide, outstanding for training personnel on general and specific topics in cellular telecommunications. It should be a part of everyones professional library. A must if you are thinking of working in the telecommunications field or just wish to understand what its all about.

A TinyOS-Based Ad Hoc Wireless Sensor Network: Introduction, Versatile Application Design, Implementation Review

A TinyOS-Based Ad Hoc Wireless Sensor Network: Introduction, Versatile Application Design, Implementation

This book is a summary of the author's MS thesis. I bought it to learn the networking aspects of tinyOS. This paperback is ~80 pages long and less than half of those have anything to do with Networking (the rest are on sensors). I went through the book in an evening and perhaps learned 4-5 pages worth of new information (and I am relatively new to networking and tinyOS).
The new concept introduced is something referred to as Reverse Path Routing - a way of getting from the base station to individual nodes. I was not convinced that the algorithm is stable or usable in a real world deployment.

A well written book that actually describes a wide variety of wireless technologies without hiding behind overly complex explainations, formulas, and archane diagrams. G3 wireless telephony was actually explained in detail, without resorting to quoting marketing droids and droning on and on about how it will change our lives. This book actually talks about what the technology is and then explains it in a version of english I can actually understand....instead of marketspeak..

I thought this book was great. It struck the right balance between being a comprehensive primer on the topic, having enough detail if you decide you need it and not going into too much detail about stuff that is dealt with elsewhere - like CGI programming or generating pages from languages like Perl. If you want that then buy Leraning Perl or CGI programming on the World Wide Web.

The next generation of mobile communicators is here, and deliveringcontent to them will mean programming in WML (Wireless Markup Language)and WMLScript, the languages of the Wireless Application Environment(WAE). The WAE allows information in almost all applications to beformatted for display on mobile devices, such as cell phones, andenables the user to interact with the information.

Why learn yet another technology? According to some estimates, 75percent of web document viewing by the year 2002 will be throughnon-desktop devices, many using wireless technologies. Clearly, the futureis wireless. For web developers who want to get up to speed quickly inthese languages, Learning WML & WMLScript maps out in detail theWAE and its two major components, WML and WMLScript.

Fortunately, the WAE provides a World Wide Web-like model for writingapplications, incorporating several key features of the Web to ease thetransition for developers. Almost all wireless applications can bewritten with WML, which replaces HTML in the wireless environment, andWMLScript, which replaces JavaScript. With this book, web developerswith some knowledge of programming and C, Java, or JavaScript syntax caneasily master both languages.

Chapter by chapter, Learning WML & WMLScript takes readersthrough the following WML topics:

Decks, templates and cards
User Interaction
Variables and contexts
Tasks, events, and timers
Text and text formatting

WMLScript topics include:

Data types, conversions and variables
Operators and expressions
Statements
Functions
Standard libraries

Learning WML & WMLScript is the resource of choice forapplication developers who want to upgrade their skills and their sitesso they won't be left plugged in during the wireless revolution.
