Inter-Vehicular Communication - From Edge Support to Vulnerable Road Users II (Dagstuhl Seminar 22512)

Authors: Ana Aguiar, Onur Altintas, Falko Dressler, Gunnar Karlsson, and Florian Klingler

Published in: Dagstuhl Reports, Volume 12, Issue 12 (2023)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 21262 "Inter-Vehicular Communication – From Edge Support to Vulnerable Road Users II". Looking back at the last decade, one can observe enormous progress in the domain of vehicular networking. In this growing community, many ongoing activities focus on the design of communication protocols to support safety applications, intelligent navigation, and many others. We shifted the focus from basic networking principles to open challenges in edge computing support and, as a novel aspect, on how to integrate so called vulnerable road users (VRU) into the picture.

10403 Abstracts Collection – Impact of Human Mobility on Communications : Measurement, Analysis, Modeling, and Simulation

Authors: Kevin C. Almeroth, Gunnar Karlsson, Cecilia Mascolo, and Jörg Ott

Published in: Dagstuhl Seminar Proceedings, Volume 10403, Impact of Human Mobility on Communications : Measurement, Analysis, Modeling, and Simulation (2011)

Abstract
From 06.10.2010 to 09.10.2010, the Dagstuhl Seminar 10403 ``Impact of Human Mobility on Communications : Measurement, Analysis, Modeling, and Simulation'' was held in Schloss Dagstuhl~--~Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

On the Performance of Pedestrian Content Distribution

Authors: Gunnar Karlsson, Olafur Ragnar Helgason, and Vladimir Vukadinovic

Published in: Dagstuhl Seminar Proceedings, Volume 9071, Delay and Disruption-Tolerant Networking (DTN) II (2009)

Abstract
Mobile communication devices may be used for spreading multimedia data without support of an infrastructure. Such a scheme, where the data is carried by people walking around and relayed from device to device by means of short range radio, could potentially form a public content distribution system that spans vast urban areas. There are basically only three system parameters that can be determined in the design: the transmission range of the nodes, the setup time when nodes make a contact, and their storage capacity. The transport mechanism is the flow of people and it can be studied but not engineered. The question addressed in this paper is how well pedestrian content distribution may work. We answer this question by modeling the mobility of people moving around in a city, constrained by a given topology. The model is supplemented by simulation of similar or related scenarios for validation and extension. Our conclusion is that contents spread well with pedestrian speeds already at low arrival rates into a studied region. Our contributions are both the results on the feasibility of pedestrian content distribution and the queuing analytic model that captures the flow of people.
