WIRELESS AD HOC AND SENSOR
NETWORKS (1ST ED.)

Wireless ad hoc and sensor networks
remain a hot research topic, with the goal
of translating abstract concepts into real-life civilian and military applications.
Interested readers can find an excellent overview of
the state of the art in Wireless Ad Hoc and Sensor Networks.
Each chapter presents cutting-edge research topics with
a well-orchestrated analytical approach, underlining the
interdependencies that exist between the various system
components. This approach reflects the very nature of ad
hoc and sensor networks, characterized by theoretical and
practical capacity limitations, offering readers a down-to-earth approach to actual implementations.
As an example of the interlaced discussions found in
the text, chapter 2 covers DSR (dynamic source routing),
AODV (ad hoc on-demand distance vector), OLSR (
optimized link state routing), TBRPF (topology dissemination
based on reverse-path forwarding), ZRP (zone routing
protocol), and LAR (location-aided routing) and is highly
correlated to the discussion in chapter 3 of QoS extensions for routing protocols AODV and OLSR. Chapter 4
addresses the related topic of multicast ad hoc routing.
Chapters 5 and 8 provide the foundations for the
development of autonomous self-organized application-oriented architectures. Chapters 6 and 7 detail service
discovery protocols for mobile networks.
The remaining chapters cover fault-tolerant distributed algorithms, code mobility in sensor networks, and
This book provides a useful reference on the architectural aspects of ad hoc and sensor networks to both
students and practitioners. —Alessandro Berni
PRO WEB 2.0 APPLICATION
DEVELOPMENT WITH GWT
Jeff Dwyer, Apress, 2008, $44.99,
This book was written for deploying
GWT (Google Web Toolkit) applica-
tions. It is organized into two parts: Part 1, consisting of
two chapters, is a short and proper introduction to Web
2.0; Part 2 is devoted to building and deploying a GWT
Any treatment of Web 2.0 and GWT should commence with RIA (rich Internet applications), as does this
book; the introduction to RIA is given in terms of Ajax,
DOM (document object model) scripting, and Google
Maps. Speed factors, such as prefetching and background
loading, are appropriately introduced in chapter 1.
Advantages of GWT are demonstrated in chapter 2.
Part 2 begins with an overview of the sample domain
ToCollege.net. College browser, maps, and MyList are
introduced as objects of the domain. The domain is slowly
developed into a larger ecosystem, with GWT and the
Spring MVC (model-view-controller). The book includes
a good deal of code, MVC design objects, and macros.
Dwyer elaborates on site security, with discussions of
GWT’s security features against cross-site scripting attacks.
One chapter is dedicated to Google Maps and its API,
and presents the GUI integration with Maps. Another
chapter examines suggest boxes and full-text search.
Dwyer includes a lot of discussion on classes that form
the building blocks of creating forums for the site. The
maintenance of history and threads is the challenge, and
Dwyer discusses this very well. He presents authorization
and security issues, and the post-login scenario is considered for elaboration of authentication. Securing HTML is
discussed in light of GWT’s protection mechanism. The
book explains well, with code, how GWT works with Ajax
Almost everyone starts with searching on the Internet,
so the search engine should be properly built into the
system and optimized. The book presents all the relevant
technologies, such as cache and serialization.
The book ends with the tools and steps for building
ToCollege.net. It includes GWT installation, building a
calculator, setting up a database, and running the site.
This is a good book to be added to any Web developer’s library. Dwyer’s inclusion of the relevant code makes
the book even more attractive. —S. Balaraman
