Wi-Fi(TM), Bluetooth(TM), Zigbee(TM) and WiMax(TM) Review

Wi-Fi(TM), Bluetooth(TM), Zigbee(TM) and WiMax(TM)

I bought this book because it promised broad coverage of the currently most important non cellular, wireless technologies. We'll it delivers on the breadth of information but this is an extremely difficult book to read. Here's why:
1. It's coverage of the wireless subjects seems spotty and disorganized in that it jumps around between hardware and software subjects in an almost aimless way. Generally, the book does not provide sufficient and clear coverage of the system level or architectural issues for a given technology before deep diving into selected areas of technical detail. There tends to be too much detail in many specific technical areas without sufficient discussion of how the pieces work together.

2. It's written in broken English (actually seems to be poorly translated from French);
3. It is very poorly edited (includes many incorrect references to figures and tables, incomplete and broken sentences);
4. It suffers from death by acronyms. The book introduces the words behind the acronym once then never seems to use the "words" again, only the acronym. Unless you're already an expert in the subject, reading requires you to access the 16 page acronym dictionary after reading every few sentences. This is doable but makes reading difficult and clearly distracts the reader from appreciating the technical concepts being communicated.
Although the book seems to have a good deal of useful information. I would recommend that potential buyers look around for other coverage of the material before buying this hard to read book.

The book provides a complete and detailed description of the recent wireless technologies including Wi-Fi, Bluetooth, ZigBee and WiMAX. These technologies are considered to be important topics in the telecommunication industry in the next decade. Some critical subjects are particularly developed such as security, quality of service, roaming and power conservation. The book also includes some chapters on practical aspects.

Algorithms and Protocols for Wireless, Mobile Ad Hoc Networks (Wiley Series on Parallel and Distributed Computing) Review

Boukerche has amassed a collection of papers about the status of MANETs - Mobile Ad Hoc Networks. These deal with mobile nodes that are NOT cellphones. While there has been a vast amount of research and development on cellular radio networks, the book explains that these have huge simplifications compared to the problems contemplated by the book. A cellular network has fixed basestations, that are not power limited, and which do all the routing. A MANET consists of nodes that typically are all moving, and there might be no hierarchy of supernodes that can do the routing. Hence each node has to somehow have some routing ability.
Another limitation of a MANET is that the nodes are often severely power limited. So transmission range, bandwidth and processing ability are crimped.
Given all this, it is remarkable that any progress could even be made for MANETs. Yet the book shows that considerable work has been done. The use cases include warfare, where fixed nodes might be targets for the enemy.
Another important case is a VANET - a Vehicle Ad Hoc Network. Imagine cars flowing down a road. They could one day be able to communicate with each other, perhaps to warn of congestion and to aid routing. But many key questions remain unresolved. The chapters on VANET suggest that this topic is highly undeveloped. Which might be an opportunity for you to contribute.

Learn the fundamental algorithms and protocols for wireless and mobile ad hoc networks
Advances in wireless networking and mobile communication technologies, coupled with the proliferation of portable computers, have led to development efforts for wireless and mobile ad hoc networks. This book focuses on several aspects of wireless ad hoc networks, particularly algorithmic methods and distributed computing with mobility and computation capabilities. It covers everything readers need to build a foundation for the design of future mobile ad hoc networks:

Establishing an efficient communication infrastructure

Robustness control for network-wide broadcast

The taxonomy of routing algorithms

Adaptive backbone multicast routing

The effect of inference on routing

Routing protocols in intermittently connected mobile ad hoc networks and delay tolerant networks

Transport layer protocols

ACK-thinning techniques for TCP in MANETs

Power control protocols

Power saving in solar powered WLAN mesh networks

Reputation and trust-based systems

Vehicular ad hoc networks

Cluster interconnection in 802.15.4 beacon enabled networks

The book is complemented with a set of exercises that challenge readers to test their understanding of the material. Algorithms and Protocols for Wireless and Mobile Ad Hoc Networks is appropriate as a self-study guide for electrical engineers, computer engineers, network engineers, and computer science specialists. It also serves as a valuable supplemental textbook in computer science, electrical engineering, and network engineering courses at the advanced undergraduate and graduate levels.
