Recent advances in communications technologies have witnessed a growing and evolving multimedia content delivery market based on information gathering, manipulation, and dissemination. It is a fact that personal communications, computing, broadcasting, entertainment, etc. have turned into streams of multimedia content, and the various communication and network technologies have become the means...

Understanding the functionality of a communications system or network in the wake of failures is provided by survivability analysis. A great deal of attention has been focused on survivability of high speed networks and of ad hoc networks supporting battleeeld communications. Very little attention has been placed on the unique survivability issues pertaining to mobile systems supporting cellula...

Auctions have emerged as the primary means of assigning spectrum licenses to companies wishing to provide wireless communication services. Since July 1994, the Federal Communications Commission (FCC) has conducted 33 spectrum auctions, assigning thousands of licenses to hundreds of firms. Countries throughout the world are conducting similar auctions. I review the current state of spectrum auct...

In this paper, we describe an undergraduate parallel programming course based upon networked workstations. The course is offered on the NC-REN (North Carolina Research and Education Network), a private telecommunications network which interconnects universities in North Carolina and provides multiway, face-to-face video and audio communications. Course materials are described and made available...

Spurred by the vision of seamless connectivity anywhere and anytime, ubiquitous and pervasive communications are playing increasingly important role in our daily lives. New types of applications are also affecting behaviour of users and changing their habits, essentially reinforcing the need for being always connected. This clearly represents a challenge for the telecommunications community esp...
