The comparatively young floating car technology is mostly used to get information about travel times which however are more attractive to navigation and route guidance. Concerning traffic management applications such as traffic light control, it is more li ...
We present the architecture and design of the IANOS scheduling framework. The goal of the new Grid scheduling system is to provide a general job submission framework allowing optimal positioning and scheduling of HPCN applications. The scheduling algorithm ...

There is a number of highway transportation infrastructures where traffic flow arriving on a higher number of lanes must merge into a lower number of lanes within a limited space, e.g., merging highways, merging on-ramps, toll plazas, work zones. When the ...
We study networks of FIFO nodes, where flows are constrained by arrival curves. A crucial question with these networks is: Can we derive a bound to the maximum delay that a packet can experience when traversing the network, and to the maximum queue size at ...
An analytical model for real-time estimation of travel times along signalized arterials was developed. The application of the model on two arterial sites and comparisons of the estimated travel times with simulated and field data show that the model accura ...
We consider queueing networks (QN) with feedback loops roamed by ``intelligent'' agents, able to select their routing on the basis of their measured waiting times at the QN nodes. This is an idealized model to discuss the dynamics of customers who stay loy ...
Networks on Chips (NoCs) are required to tackle the increasing delay and poor scalability issues of bus-based communication architectures. Many of today’s NoC designs are based on single path routing. By utilizing multiple paths for routing, congestion in ...
This paper addresses the problem of the transmission of scalable video streams to a set of heterogeneous clients through a common bottleneck channel. The packet scheduling policy is typically crucial in such systems that target smooth media playback at all ...
With the latest developments in video coding technology and fast deployment of end-user broadband internet connections, real-time media applications become increasingly interesting for both private users and businesses. However, the internet remains a best ...
We demonstrate that, contrary to what is generally believed, the existing end-to-end delay bounds apply only to GR nodes that are FIFO per flow. We show this by exhibiting a counter-example. Then we show that the proof of the existing bounds has a subtle, ...
