Routing and Router Basics - WANs AND ROUTERs
A wide-area network (WAN) is a data communications network spanning a large geographic area such as a state, province, or country. WANs often use transmission facilities provided by common carriers, for example, telephone companies. These are the major characteristics of WANs: They connect devices that are separated by wide geographical areas. They use the services of carriers such as the Regional Bell Operating Companies (RBOCs),...

Performance modeling and analysis of bluetooth networks
Bluetooth is a recent wireless communication technology specifically intended for short range ad hoc networking. It was initially envisaged as a simple cable replacement technology to connect various mobile, portable, and fixed devices such as PDAs, mobile phones, laptops, and printers, but its use has soon spread to include various general purpose networking tasks, and a number of Bluetooth-enabled devices have appeared on the market. In...

Optical switching and networking handbook
Before you begin to read this book, please take a moment to read these introductory comments. The title of the book may be misleading for many people: For the engineering person, this may sound like the bible of optical networks and switching systems. Not so! This is not an engineering book and will not dig into the gory details of bits and bytes, ohms and lamdas, and so on. It will help an engineering person to understand the marketplace for...

Whereas today’s expensive wireless infrastructure depends on centrally deployed hub-andspoke networks, mobile ad hoc networks consist of devices that are autonomously selforganizing in networks. In ad hoc networks, the devices themselves are the network, and this allows seamless communication, at low cost, in a self-organized fashion and with easy deployment. The large degree of freedom and the self-organizing capabilities make mobile ad hoc...

Satellites for communication services have evolved quite significantly in size and power since the launch of the first commercial satellites in 1965. This has permitted a consequent reduction in the size of earth stations, and hence their cost, with a consequent increase in number. Small stations, with antennas in the order of 1.2–1.8 rn, have become very popular under the acronym VSAT, which stands for ’Very Small Aperture Terminals’....
