 pdf fileMultiaccess 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.

 pdf fileDATA NETWORKS - Queing Data Networks
DATA NETWORKS 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.

 pdf fileRouting 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).

 pdf fileWireless 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.

 pdf fileHacking 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.

 pdf fileA 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 departmentsí 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.

 pdf fileEnergy-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.
