Today, a large part of the traffic carried by the Internet is generated by file-sharing applications based on the P2P paradigm. Moreover, P2P traffic has particular features, quite different from the ones generated by "classical" data applications, and generally causes highly dynamic and distributed traffic matrixes that heavily stress network infrastructures. With this respect, it is reasonabl...

In this paper, we present a synthetic traffic model for the Universal Mobile Telecommunication Systems (UMTS) based on measured trace data. The analysis and scaling process of the measured trace data with respect to different bandwidth classes constitutes the basic concept of the UMTS traffic characterization. Furthermore, we introduce an aggregated traffic model for UMTS networks that is analy...

International incoming grey traffic is currently one of the most important issues for both the Regulator and legal telecommunication operators in Pakistan. The major reason for higher grey traffic in Pakistan is because of international settlement rates which are higher than the cost of domestic termination rate. The grey traffic operators gain financial advantage by offering low international ...

Not available services or service interruption could have different impact to our social life. Emails or messages which are not delivered in a proper time-frame could lead to omit a meeting or a discussion with colleagues. Interconnected CPS in different domains, like autonomous driving, smart grids, Industry 4.0, needs a guaranteed and safe delivery of information. Nowadays distributed applica...

Traffic surveillance and investigation is important to increase the safety on roads. Vehicle detection and tracking in road surveillance is classical task in computer vision and critical component in modern traffic monitoring system. Intelligent transport system (ITS) brings advanced computing, sensing and telecommunication technologies to transport related problems. Many traffic surveillance s...

This paper deals with various applications of conservation laws on networks. In particular we consider the car traffic, described by the LighthillWhitham-Richards model and by the Aw-Rascle-Zhang model, the telecommunication case, by using the model introduced by D’Apice-Manzo-Piccoli and, finally, the case of a gas pipeline, modeled by the classical p-system.
