Average Reviews:
(More customer reviews)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.
