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

چکیده
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. Digital Object Identifier 10.4230/OASIcs.KiVS.2011.121

Kooperative Peer-to-Peer-basierte Verkehrsinformationssysteme
This thesis deals with cooperative traffic information systems, which support the driver of a car in selecting a route, based on traffic information collected by other cars. System participants contribute measurements of the traffic situation in their vicinity (e. g., current traffic flow speed) and use the measurements made by other drivers to find the fastest route to their destination with r...
متن کاملA Genetic Programming-based trust model for P2P Networks
Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . This paper investigates the use of genetic ...
متن کاملGGRA: a grouped gossip-based reputation aggregation algorithm
An important issue in P2P networks is the existence of malicious nodes that decreases the performance of such networks. Reputation system in which nodes are ranked based on their behavior, is one of the proposed solutions to detect and isolate malicious (low ranked) nodes. Gossip Trust is an interesting previously proposed algorithm for reputation aggregation in P2P networks based on t...
متن کاملA Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...
