The need to store data and information permanently, for their reuse in later stages, is a very relevant problem in the modern world and now affects a large number of people and economic agents. The storage and subsequent use of data can indeed be a valuable source for decision making or to...

A VPN (Virtual Private Network) simulates a secure private network through a shared public insecure infrastructure like the Internet. The VPN protocol provides a secure and reliable access from home/office on any networking technology transporting IP packets. In this article we study the...

Wireless ad hoc single-rate environments typically use a Distance Vector routing with a metric based on hop-count minimization. In practice, the technique of minimizing the distance does not reward in the case of multirate, therefore it may be prefereable to use protocols privileging link...

Learning is a continuous process, without end, which takes place throughout life, and is the result of the interaction of an individual with a physical external environment, a social context or with herself. In what new technologies may help improving and making more effective the interaction of...

We propose an algorithm for computing "main stable sets" recently introduced by Ciardiello, Di Liddo (2009) on effectiveness form coalitional games modeled through a directed pseudograph. The algorithm is based upon a graph traversing method exploring extended paths minimal in coalitions and we...

Wireless (and hence mobile) communication networks have become an integral part of our society, significantly enhancing communication capabilities; mobile ad hoc networks (MANETs) extend this capability to any time/anywhere, providing connectivity without the need of an underlying...

The generation of realistic data sets in a Combinatorial Auction may be a challenging problem. Well-formed data sets are very useful in the evaluation of algorithms trying to solve the winner determination problem. In this paper a general data set generation scheme is presented, both from an...

Technological development and explosion of computing tools allow today to make best use of modeling methodologies that in the past were not able to perform the calculations necessary for the mathematical representation of a complex system. This paper illustrates some directions in literature...

This paper illustrates a new approach to labeling ("object classification") problems, and it targets the simplification of a (computationally) complex algorithm based on Faugeras and Berthod's theorem.
