In this paper we present the design of an infrastructure-less ad-hoc inter-vehicle communication system that fulfills these requirements with respect to the boundary conditions in the railway environment, where a limited communication range and relatively high speeds of nodes cause the network to be highly dynamic. Moreover, in areas with high user densities the common media access is a challenge due to limited bandwidth and interference from other wireless systems.","PeriodicalId":228148,"journal":{"name":"2009 IEEE Vehicular Networking Conference (VNC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129998018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the FI constitutes a large portion of the packet which seriously compromised the throughput of the D-TDMA. We are proposing a technique for increasing the throughput by reducing the length of the FI without jeopardizing the packet success rate. Our technique, which is based on FI redundancies, lets the terminals transmit the relevant information when necessary. A computer simulation was conducted for an urban environment in which vehicles are moving. The simulation results show that the proposed technique significantly increases the throughput without degrading the quality of the D-TDMA protocol.","PeriodicalId":228148,"journal":{"name":"2009 IEEE Vehicular Networking Conference (VNC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115759202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inter-vehicle cooperation is made possible thanks to the revolution in the wireless mobile ad hoc network. This paper presents an application of the V2V communications. The car tracking using the GPS receivers is not always ideal in urban areas. To resolve this problem, our original approach is based on using data issued from vision systems when the GPS signal is not available or has a poor quality due to multi-tracks or bad satellite visibility. The method relies on the particle filter for the fusion of the GPS data and the vision data that will be collected from the loading system in the vehicles. Multiple results from different scenarios experimented on our fleet of communicating vehicles carried out in real conditions prove the feasibility of this approach.","PeriodicalId":228148,"journal":{"name":"2009 IEEE Vehicular Networking Conference (VNC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124986696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When deployed, the system will provide a driver stopped at a thru-stop intersection information about the available gaps in the mainline road traffic stream. The system uses surveillance sensors alongside the major road to determine the state1 of the intersection; this state information is used to determine whether the gaps that exist are unsafe, thereby triggering a warning to a driver not to initiate the desired maneuver. The system is capable of sending intersection state information to the vehicle (I2V) so that gap information can be displayed in the vehicle. Low cost automotive radar/laser sensors form the basis of the surveillance system. Described herein is a performance evaluation of a Delphi ESR radar sensor (ESR), an Ibeo Lux laser sensor (LUX), and a Smartmicro Umrr9 radar sensor (UMRR9). Each sensor was mounted adjacent to the shoulder on US 52 while a probe vehicle equipped with dual frequency, carrier phase DGPS was driven past. The accuracy of the position and speed measurements for each sensor were determined by comparison with the DGPS position and speed measured at the probe vehicle. An analysis was conducted to determine which sensor provided the best performance:cost ratio when used as a CICAS-SSA mainline sensor.","PeriodicalId":228148,"journal":{"name":"2009 IEEE Vehicular Networking Conference (VNC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129230187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
