Rating: Summary: Excellent & Comprehensive Book ! Review: Folks, I am excited about the arrival of this book. Unlike those books written by Perkins and Johnson, this book provides an excellent coverage on various topics, such as MAC, TCP, service discovery, routing and multicasting. The treatment is in great depth and the comparison is comprehensive. The author is more interested in the content than "political views", which should not be present in an educational book. Authors should be free to comment on his book about variousprotocols. As far as from a reader's point of view, I care much about the effort put into the book and how informative and useful it is. This one, I felt, is excellent. There is no other book comparable to this at the moment.
Rating: Summary: Re: Nice book to have! Review: I am a graduate PhD student and found this book extremely useful. I had spent many years in industries. It is comprehensive and provides good information on the topics. I think this book was written for educational purposes. Although I knew that there are other researchers out there, not many care to write a book! Also, it is nice to have an author who is one of the few pioneers to author this book. I do not view a book as a "bible" and hence I do not expect books to be free from errors. I spotted some typos but overall this book is valuable for me. The review written by the reader from midwest seemed inappropriate to me. It sounded to me that he does not have sufficient networking background to understand the topics. For example, packet size will impact total packet propagation time. BT has 7 devices plus 1 controller (as stated in the book). Section 8 is about experimental results from a field trial, not simulation! Again, overall I am happy with this book. No one else has written a better book in this area yet. :-)
Rating: Summary: Good use for defense work Review: I have been using this book for parts of my defence work. It has provided me the content I needed and clear enough for me to understand. We were looking for performance numbers and this book provided us with the number we wanted from a working system. Good coverage on issues overall.
Rating: Summary: Good book for consultants Review: Luckily I bought this book. It teaches me from basic to more complex topics, allowing me to understand and master ad hoc networking. Found it rather a timely book for consultants in the field of wireless office computing, networking, and automation. This book is very helpful, with lots of diagrams and clear explanations. This is the book I need and I highly recommend it to others. My engineers are reading them! - from VP in an IT consulting firm.
Rating: Summary: Not a book to have Review: Luckily I had an ability to read this book before buying. I was very dissapointed with the content. There are quite a number of serious errors especially in TCP description. The coverage lacks depth. The new methodology proposed by the author in his unicast routing algorithm is just another kind of metrics with the same good old SPF idea behind (the description of the idea makes good 1/3 of the book). I would not recommend it to anyone.
Rating: Summary: lack depth in all subjects Review: performance data are collected in a purely fixed wireless environment, lacking the most important part of mobility. it is very disappointing to read the whole book written by a PhD holder. the book introduces elementary concepts about everything. in essence, it tells nothing
Rating: Summary: Great companion for the Perkins Book Review: Presentation is clear, logical, lucid, and understandable. My compliments to the author. I think this book is important not only to the reader with a direct interest, but also as a tool for communicating aspects of the subject to management.
Rating: Summary: My comments (from New York City) Review: This book by TOH is great. The book is well written and I found lots of technical topics discussed in great depth and with great insights. The part I like was how he compared different routing protocols, and carefully explaining the advantages and disadvantages. He is also sharp in telling the history of these protocols and which features/algorithms were first proposed by who. This is great for subsequent followers in the field of ad hoc networking. Illusions can therefore be eliminated. Pioneers in this field are clearly identified, for which the author himself is one of them. TOH is by far the only inventor/author who implemented this own protocol in great depth, getting it to work, and also with real implementation results. Other protocol proposers seem to just make a lot of noise in conferences but their protocols are rather lacking. I strongly recommend this book since it is comprehensive and was written by a technical expert and pioneer in this field. Other competitors did not stand a chance since they did not demonstrate their ability to understand and address the various technical topics (such as MAC, service discovery, TCP, multicast, power management, etc.,) in the field of ad hoc mobile wireless networks. None of the other MANET protocol people wrote any great book but TOH did. I like this book very much.
Rating: Summary: Broad coverage but written in a hurry Review: This book gives a broad overview over ad hoc wireless networks. Being broad in 300 pages necessarily implies being shallow, at least in some of the topics. Interestingly, the topic that's covered in most detail is the author's own routing algorithm, which is not one of the most popular ones. While it certainly provides valuable information, the book has some serious flaws and inconsistencies in both contents and presentation. Some examples of flaws include: (1) Propagation delay does _not_ depend on packet size. (2) TCP does _not_ establish a virtual circuit. (3) The TCP header does _not_ include the IP address. (4) Bluetooth supports 8 (not 7) devices per piconet; transmit power is not 800uA (power is not expressed in amps anyway). (5) If for a two-hop connection, the throughput is 1/2 (compared to the link capacity), and for a three-hop connection, it's 1/3, that can _not_ be extrapolated to 1/N for an N-hop connection. Rather, the throughput will stay constant after 3-5 hops, depending on the ratio between the transmission and interference radius. (6) A constant function f(x)=c is _not_ a linear function. (7) The output power of the Lucent WaveLAN card is not -80dBm. Section 8 is heavily based on simulation, and the text lacks a detailed interpretation that could be much more insightful than just the simulation results. The impression that this book was written in a big hurry stems from the following facts: Figures are helpful but are sometimes drawn carelessly (including most of the photographs); the book has lots of typos; at one point a whole paragraph is repeated word by word two pages later, which should have been discovered when proofreading. Personally I would refrain from calling Bluetooth "ridiculous" - there were a lot of smart people involved in the development. If this is the author's opinion, he should declare it as such. In summary, I was quite disappointed by the book.
Rating: Summary: Good as a introduction book. Review: This book is very good for introduction in ad-hoc networks and protocols. It also can be used for quick start in this field.
Another good thing for this book, it is very useful when you write your research paper or thesis because the author already summalized concepts and pros/cons of many ad-hoc network protocols. However, if you need to know and learn in deep detail, do not buy it. The author should insert "Introduction" in the title of this book. Furthermore, the price of this book is too expensive that it should be.
