The evolution of the Internet has come to a point where almost at the same time, governments all around the world feel the need for legislation to regulate the use of the Internet. In preparing the legislation, consultations were called by various governments or by the corresponding regulation bodies. We describe in this paper the various...

The traffic on the internet has known to be heavy tailed: the size of file transfers through FTP or HTTP applications, as well as those transferred by P2P applications has been observed to have a very heavy tail. Typically modeled as Pareto distributed with parameter between 1.05 to 1.5, the file size has infinite variance. This is the source...

Internet growth has allowed unprecedented widespread access to cultural creation including music and films, to knowledge, and to a wide range of consumer information. At the same time, it has become a huge source of business opportunities. Along with great benets that this access to the Internet provides, the open and free access to the...

Mobility models studied in the networking community usually assume independence between the movement of individuals. While this may well model sparse networks, there are many scenarios that might not follow this assumption. In contrast, within other communities, such as road traffic engineering, biology and computer graphics, models of mobility...

Awarded as one of the best papers.

The calculation of the center of a set of points in an open space, subject to a given metric, has been a widely explored topic in operations research. In this paper, we present the extension of two of these centers, the median and the min-max centers, when there is uncertainty in the location of the points. These points, modeled by...

Hahn and Wallsten [3] wrote that net neutrality usually means that broadband service providers charge consumers only once for Internet access, do not favor one content provider over another, and do not charge content providers for sending information over broadband lines to end users." In this paper we study the implications of being...

In this paper, the authors present a methodology to solve the weighted barycenter problem when the data is inherently fuzzy. This method, from data clustered by expert visual inspection of maps, calculates bi-dimensional fuzzy numbers from the spatial clusters, which in turn are used to obtain the weighted fuzzy barycenter of a particular area....

En muchas democracias, es condición...
