To alleviate the effect through situational awareness, various traffic service providers aggregate traffic information using a variety of inputs such as probes, toll collection etc. This aggregated information is fed back to the drivers to achieve congestion avoidance and provide arrival-time estimates. In this paper, we outline a framework for a distributed vehicle traffic navigation system. The proposed system leverages a multi-hop vehicular network to gather local information. Such information can be elusive to traffic service providers in terms of timeliness and accuracy. Based on the gathered information, a distributed scheme is proposed that locally determines the shortest time travel paths. The proposed system can function independently or can complement an existing infrastructure-based system and can capture the dependence between route decisions of different vehicles in a given area. Based on performance evaluations, we observe that the proposed protocol can significantly enhance local route decisions leading to better traffic flow and road utilization.","PeriodicalId":228148,"journal":{"name":"2009 IEEE Vehicular Networking Conference (VNC)","volume":"47 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":"127936463","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}

In such environments, wireless clients have a variety of affiliation options. The state of the art mechanism behind such a decision typically relies on received signal strength indicator (RSSI). This approach however, might yield unbalanced traffic load among APs. In this paper, we design intelligent AP selection algorithms for Vehicle to wireless Infrastructure opportunistic (unplanned) communications (V2I). Our objective is to increase the distance for which the vehicle is in the coverage area of the selected AP. This distance is quantified based on realistic criteria like the distance between the vehicle and the AP and the direction of the vehicle. We design two intelligent approaches: SAPS (Scan-based AP Selection), and HAPS (History-based AP Selection). Through a simulation study, we demonstrated that SAPS and HAPS, compared to RSSI-based solution, achieve lower overhead and higher amount of data in a region with an average density of APs. Our findings show also that much data would be transferred at lower speeds. Moreover, either SAPS or HAPS permits to the vehicle to efficiently profit from the time it is associated to an AP more than a classic solution based on the RSSI do.","PeriodicalId":228148,"journal":{"name":"2009 IEEE Vehicular Networking Conference (VNC)","volume":"33 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":"115805778","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}

We used these measurements to characterize vacant TV channels a along major interstate highway (I-90) in the state of Massachusetts, USA. By characterizing the availability of vacant TV channels in the 470–806 MHz frequency range, we show the trends in the availability of vacant channels from a vehicular dynamic spectrum access perspective. We also describe the design constraints imposed on a point-to-multipoint communications based architecture in such a setting. Specifically, we described a general geo-location database approach to create a spectral map of available channels in a given geographical area. We presented the results obtained by applying such a technique in the state of MA over several locations on I-90. Furthermore, we presented a discussion on the implications of the non-contiguous channel availability in the TV spectrum on the design of a cognitive radio transceiver from the perspective of vehicular communications. In our future work, we will be presenting a comparative study of the channel availability in the above mentioned geographical area before and after the switch-over carried out on June 12, 2009.","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":"129825035","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}

This paper addresses the problem of redundant forwarding of messages that occur during broad- cast and proposes an adaptive forwarding mechanism which controls the amount of redundant messages thereby improving message dissemination over a VANET. The mechanism will enable a node to efficiently forward a message and at the same time refrain other potential forwarders of the same message in a chosen area to forward the message. The algorithm exploits the density of nodes on the network for its functionality and will make an adaptive sector under which the redundant nodes will be refrained from sending the same message. The area of the sector for a particular node will be proportional to the density of its neighbors that are within the node's communication range. The proposal assumes that the nodes in the VANET are aware of their surroundings up to a certain area by periodic exchange of location information from each of the nodes. The mechanism will enable routing algorithms and/or beaconing systems to consume lesser bandwidth and thereby enhance the efficiency of the algorithm itself.","PeriodicalId":228148,"journal":{"name":"2009 IEEE Vehicular Networking Conference (VNC)","volume":"11 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":"129929641","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}
