This Floating Car Data (FCD) can be used to detect traffic disturbances. Although today's vehicles are able to determine their position on a per-lane level, FCD is typically only used on a per-street level granularity. In this paper, we show that using the fleet-data from one Original Equipment Manufacturer (OEM) alone as the database (i. e., on a backend) is not sufficient to detect lane-level traffic phenomena, independent from the accuracy of the vehicle localization. We thus present a high-resolution telemetry service based on heterogeneous Inter-Vehicle Communication (IVC). We introduce a holistic IVC simulation framework which we make publicly available and use it to experimentally verify the proposed telemetry service. Results show a significant leverage of IVC on both the resolution of FCD and the accuracy of detecting lane-level traffic phenomena.","PeriodicalId":106267,"journal":{"name":"IoV-VoI '16","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115157034","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}

Clustering communication nodes promise to reduce channel contention, enable building backbones and might improve spatial reuse. In this paper we propose a seemingly simple, yet unexplored idea: extending 802.11 frame bursting MAC access to multiple stations aggregated into a cluster. The focus of the paper is thus not building a cluster, but exploring what is the gain that can be achieved by the standard 802.11p channel access if we introduce the principle of frame bursting (presently not allowed in 802.11p standard, but the key factor for the efficiency of 802.11n/ac WiFi channel access). The key scientific question is if we can extend the frame bursting mechanism so that only the cluster leader contends for the channel reserving a Transmission Opportunity that is used by all the vehicles in the cluster transmitting a coordinated burst of frames. We describe in detail the idea, highlight the problems that can be encountered in its implementation (the devil, as usual is in details), and present some preliminary results for a special class of clusters: Cooperative driving platoons of cars.","PeriodicalId":106267,"journal":{"name":"IoV-VoI '16","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130331524","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 this paper we propose a new service, namely THOR (Traffic monitoring Hybrid ORiented service), able to combine two different wireless technologies and to provide real time information about vehicular traffic monitoring and incident detection. THOR relies on LTE (Long Term Evolution) and Dedicated Short Range Communication based VANETs (Vehicular ad-hoc NETworks) in a hybrid approach, which is compliant with ITS standards. This hybrid networking approach can be deployed today and can be ready for tomorrow VANET technology. We test THOR by simulations in a scenario with vehicle flows synthesized from real measured vehicular traffic traces. We provide an LTE load analysis and an assessment of incident detection capabilities. Our results are promising in terms of reactivity, precision and network traffic load sustainability.","PeriodicalId":106267,"journal":{"name":"IoV-VoI '16","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131360625","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}

With various vehicular applications equipped, these smart vehicles not only improve driving safety, but also facilitate data collection and information sharing for traffic optimization, insurance estimation, and infotainment. However, developing and testing such cloud based vehicular application is challenging due to the high cost of running the application on actual cars in various traffic scenarios. For the same reason it is also difficult to understand and model the network protocol behavior among multiple vehicles. In this paper we proposed VC-bots, a vehicular cloud testbed using mobile robot vehicles, which can emulate different types of vehicles for testing vehicular network protocols and vehicular cloud applications in various scenarios, which can be easily reconfigured without any infrastructure assistance. To facilitate software integration, we also developed a message based service framework for applications running on the robot vehicle and in the cloud.","PeriodicalId":106267,"journal":{"name":"IoV-VoI '16","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121701563","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 this paper, we design a framework to utilize radio-equipped cars as regional information hubs, which periodically disseminate public regional information (e.g., advertisements, travel tips, emergency info, etc.) over a designated geographical area in a city. The cars driving in the designated area repeatedly broadcast the data messages, allowing other drivers and pedestrians to passively obtain the information with their on-board wireless devices and/or smartphones. Although the idea follows a natural extension of the current capability of vehicular networks, vehicle densities in urban areas are typically highly non-uniform both in time and space, making it difficult to robustly disseminate data messages with minimal network load. We tackle this issue by introducing a probabilistic framework to intelligently adapt message dissemination strategy. Analyzing location broadcast messages, which are periodically exchanged among vehicles for safety applications, our protocol predicts future locations of neighboring radio-equipped vehicles and dynamically adjusts probability of message transmissions at each moment to suppress redundant network traffic. Simulation results show that our protocol can reduce the total amount of redundant message transmissions by up to 78%, while maintaining the spatio-temporal coverage of message dissemination.","PeriodicalId":106267,"journal":{"name":"IoV-VoI '16","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114551711","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}
