Autonomous driving in dynamic environments

Sascha Kolski

With the bigger number of cars on our roads every year, also the potential danger to die or get injured in road traffic increases. Most of these accidents are due to human error, while driver assistant systems like ESP help making traffic more safe. To inc ...

Overview of Traffic Signal Operation Policies for Ramp Metering

A ramp metering control algorithm includes typically two distinct components: the (most important) control strategy, which makes real-time decisions on the ramp exit flow to be implemented, and the translation of this decision into specific traffic light s ...

Schemes and architectures for wireless ad hoc networks and cooperative communication

Tarik Tabet

The focus of this thesis is on the study of decentralized wireless multi-hop networks. We are particularly interested in establishing bounds on the traffic-carrying capabilities of wireless ad hoc networks and conditions on the scalability of such networks ...

Applicability of road safety indicators to assess driving risks under Swiss road conditions

André-Gilles Dumont, Edward Chung, Minh Hai Pham

Road traffic crash is a problem in every country. According to World Health Organization, in Europe there are about 127,000 people killed and at least some 2.4 million injured each year. Incident detection algorithms to detect incidents on motorways are we ...

Code-Empowered Lightwave Networks

Camille Sophie Brès

In this paper, an architecture for code-empowered optical CDMA (OCDMA) lightwave networks is presented. The architecture is based on reconfigurable optically transparent paths among users of the network to provide high-bandwidth optical connections on dema ...

Efficient and Robust Secure Aggregation for Sensor Networks

Karl Aberer, Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski, Parisa Haghani

Wireless Sensor Networks (WSNs) rely on in-network aggregation for efficiency, however, this comes at a price: A single adversary can severely influence the outcome by contributing an arbitrary partial aggregate value. Secure in-network aggregation can det ...

SEVECOM - Secure Vehicle Communication

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Maxime Raya, Levente Buttyan

Vehicle to Vehicle communication (V2V) and Vehicle to Infrastructure communication (V2I) promise to improve road safety and optimize road traffic through cooperative systems applications. A prerequisite for the successful deployment of vehicular communicat ...

On the throughput scaling of wireless relay networks

Patrick Thiran, Olivier Dousse

The throughput of wireless networks is known to scale poorly when the number of users grows. The rate at which an arbitrary pair of nodes can communicate must decrease to zero as the number of users tends to infinity, under various assumptions. One of them ...

Mobility in wireless networks: friend or foe

Jun Luo

Wireless networking technologies allow computing devices to move while keeping them online, but the device mobility poses considerable technical challenges. Network designers, on the one hand, consider mobility to be harmful because it leads to dynamic and ...
