Vehicular networking has established itself, in the short span of the last few years, as one of the most promising fields of research within the larger context of metropolitan-scale wireless networking. Enabling vehicle-to-vehicle (V2V) and vehicle-toinfrastructure (V2I) communication, a pervasive deployment of vehicular networking technologies would have an unprecedented impact on mass road tr...

Milané To decrease traffic accidents is a declared target of Intelligent Transportation Systems (ITS). Among them, rear-end collisions are one of the most common and constitute one of the as yet unsolved topics in the automotive sector. This paper ...

Traffic control of vehicles on pre-planned paths may be based on critical sections where vehicles have to control their velocity mutually in order to avoid collisions. By analysing the geometry of critical sections carefully deadlock situations can be recognised and situations where vehicles may share a critical area under certain restrictions to speed-up their passage. Deadlock-freeness can be...

We define an integer linear programming model of combinatorial optimization problem that models reconfigurable multipath routing in a Network-on-Chip with guaranteed traffic. Based on time division multiplexing, the model allows avoiding collisions, deadlocks and livelocks in irregular network topologies, while minimizing latency. The model allows dynamic reconfigurable routing. In that case, i...

In the recent years, there is a strong interest of using switched Ethernet in factory automation. The switched Ethernet offers many attractive features such as large throughput, traffic isolation and full-duplex links. However, although using full-duplex switched Ethernet can limit the collisions to each port, the real-time features may be affected due to the collisions on an output port.This p...

BACKGROUND We established a trauma registry in 2003 to collect data on trauma patients, which is a major cause of death in the United Arab Emirates (UAE). The aim of this paper is to report on the long term effects of our early analysis of this registry. METHODS Data in the early stages of this trauma registry were collected for 503 patients during a period of 6 months in 2003. Data was colle...

Pedestrian safety is a major concern due to the vulnerability of pedestrians versus other traffic, especially in urban environment. The fatalities and injuries suffered in pedestrian collisions often intensify the perceived severity of these accidents. The problem is particularly significant for transit bus operations because their operations encounter pedestrian traffic regularly in their rout...

In this paper, we show how Network Calculus can be used to determine whether a switched network may satisfy the time constraints of a real-time application. If switched architecture are interesting in the sense that they offer flexible design and may eliminate collisions in Ethernet-based network, they are not guaranteeing end-to-end performances (in particular in terms of delay), especially wh...

It has recently been shown that distributed queuebased adaptation of CSMA’s contention aggressiveness can provably optimize network utility. However, such an approach is fragile, and was shown to suffer high performance degradation under conditions of frequent occurrence, namely; asymmetric channels, heterogeneous traffic, and packet collisions. In this work, we address the main sources of perf...
