Supporting Cooperative Traffic Information Systems through Street-Graph-based Peer-to-Peer Networks

Authors: Jedrzej Rybicki, Benjamin Pesch, Martin Mauve, and Björn Scheuermann

Published in: OASIcs, Volume 17, 17th GI/ITG Conference on Communication in Distributed Systems (KiVS 2011)

Abstract
In this paper we present a novel peer-to-peer system specifically designed to support the unique properties of traffic information systems. We discuss important design decisions, such as update strategies and algorithms for dynamic vehicular route planning. Our system is then assessed using a combination of network (OverSim/OMNeT++) and road traffic (SUMO) simulators. We discuss the network load required by our system and show the benefits—in terms of travel time savings—that users can expect from it.

Distributed Probabilistic Network Traffic Measurements

Authors: Alexander Marold, Peter Lieven, and Björn Scheuermann

Published in: OASIcs, Volume 17, 17th GI/ITG Conference on Communication in Distributed Systems (KiVS 2011)

Abstract
Measuring the per-flow traffic in large networks is very challenging due to the high performance requirements on the one hand, and due to the necessity to merge locally recorded data from multiple routers in order to obtain network-wide statistics on the other hand. The latter is nontrivial because traffic that traversed more than one measurement point must only be counted once, which requires duplicate-insensitive distributed counting mechanisms. Sampling-based traffic accounting as implemented in today’s routers results in large approximation errors, and does not allow for merging information from multiple points in the network into network-wide total traffic statistics. Here, we present Distributed Probabilistic Counting (DPC), an algorithm to obtain duplicate-insensitive distributed per-flow traffic statistics based on a probabilistic counting technique. DPC is structurally simple, very fast, and highly parallelizable, and therefore allows for efficient implementations in software and hardware. At the same time it provides very accurate traffic statistics, as we demonstrate based on both artificial and real-world traffic data.

10402 Report – Working Group on Fundamental Limits and Opportunities

Authors: Hannes Hartenstein, Geert Heijenk, Martin Mauve, Björn Scheuermann, and Lars Wolf

Published in: Dagstuhl Seminar Proceedings, Volume 10402, Inter-Vehicular Communication (2011)

Abstract
This working group investigated first steps towards finding a theoretical foundation for inter-vehicle communication. The main outcome is a sketch of a roadmap for future work in this direction.
