The paper presents different tools for distance learning that are, for example, applied for teaching a course on advanced computer networks at the Technical University of Braunschweig. Distance learning in this case comprises on-line teaching across the Internet as well as an Internet-based learning environment that provides teaching material via WWW-pages. Interactive simulation experiments an...

Computer networks are inherently social networks, linking people, organizations, and knowledge. They are social institutions that should not be studied in isolation but as integrated into everyday lives. The proliferation of computer networks has facilitated a deemphasis on group solidarities at work and in the community and afforded a turn to networked societies that are loosely bounded and sp...

In this article, we examine the Location Management costs in mobile communication networks utilizing timer-based method. From study of probabilities that a terminal changes number Areas between two calls, identify threshold value 0.7 for Call-to-Mobility Ratio (CMR) below which application method is most appropriate. We characterize valley appearing evolution with timeout period, showing time i...
