Multiaccess Communication
The subnetworks considered thus far have consisted of nodes joined by point-to-point
communication links. Each such link might consist physically of a pair of twisted
wires. a coaxial cable. an optical fiber. a microwave radio link. and so on. The implicit
assumption about point-to-point links. however. is that the received signal on each link
depends only on the transmitted signal and noise on that link.

Dimitri Bertsekas
Robert Gallager
Massachusetts Institute of Technology, Throughout the book, major concepts and principles are first explained in
a simple non-mathematical way. This is followed by careful descriptions of modelling
issues and then by mathematical analysis. Finally, the insights to be gained
from the analysis are explained and examples are given to clarify the more subtle
issues. Figures are liberally used throughout to illustrate the ideas. For lowerlevel
courses, the analysis can be glossed over; this allows the beginning and
intermediate-level to grasp the basic ideas, while enabling the more advanced
student to acquire deeper understanding and the ability to do research in the
field.

timesRouting in Data Networks
We have frequently referred to the routing algorithm as the network layer protocol that
guides packets through the communication subnet to their correct destination. The times
at which routing decisions are made depend on whether the network uses datagrams or
virtual circuits. In a datagram network, two successive packets of the same user pair
may travel along different routes, and a routing decision is necessary for each individual
packet (see Fig. 5.1). In a virtual circuit network, a routing decision is made when each
virtual circuit is set up. The routing algorithm is used to choose the communication path
for the virtual circuit. All packets of the virtual circuit subsequently use this path up
to the time that the virtual circuit is either terminated or rerouted for some reason (see
Fig. 5.2).

timesWireless Networking in the Developing World
This book was created by a team of individuals who each, in their own field, are actively participating in the ever-expanding Internet by pushing its reach farther than ever before. The massive popularity of wireless networking has caused equipment costs to continually plummet, while equipment capabilities continue to sharply increase. We believe that by taking advantage of this state of affairs, people can finally begin to have a stake in building their own communications infrastructure. We hope to not only convince you that this is possible, but also show how we have done it, and to give you the information and tools you need to start a network project in your local community.

timesMobile Networks Tutorial
The wireless industry has grown dramatically in the past 10 years, surpassing the number of wireline subscribers since 2001.
Subscribers are giving additional value to mobile phones devices which have become much more than just for communication,
with the adoption of 3G technology, mobiles are now multimedia devices delivering a variety of applications including
music, games, video, internet, and e-mail among others.

timesHacking Wireless Networks for Dummies
This book will show you quite a few of the latest tools, but an exhaustive text
covering all currently-available wireless hacking tools would require a forklift
to move, and would require you to remove all other books from your bookshelves
to make room. With this many available tools, the important factor
becomes learning how to use them effectively and efficiently.

timesA Guide to Wireless Networking and Deployment
Wireless networking provides employees seamless access to information and
applications, and they do not even need to be tied to the desktop or the wired
network. Wireless technologies help increase employee productivity and mobility,
because employees can get information when and where they need it.
Unfortunately, many IT departments’ skill sets lie within wired networking, and
poor design and implementation can severely impact the utility and security of
the wireless network. Successful implementation of a wireless network requires
understanding exactly what problems the wireless network is to solve and a solid
implementation plan.

timesEnergy-efficient Wireless Sensor Network MAC Protocol
(Abstract)
With the progression of computer networks extending boundaries and joining distant
locations, wireless sensor networks (WSNs) emerge as the new frontier in developing
opportunities to collect and process data from remote locations. WSNs rely on hardware
simplicity to make sensor field deployments both affordable and long-lasting without
maintenance support. WSN designers strive to extend network lifetimes while meeting
application-specific throughput and latency requirements. Effective power management places
sensor nodes into one of the available energy-saving modes based upon the sleep period duration
and the current state of the radio.
