During the antenna evaluation, system-level key performance indicators (KPI) like condition number and channel capacity are investigated and are compared to indicators like return loss, inter-element coupling and radiation characteristics. System-level KPI include effects due to vehicular antenna integration or channel conditions, which have an impact on the overall performance. A suitable 2D reference antenna arrangement is developed to evaluate the performance gain of the volumetric antenna design approach by performing test drives in a live LTE network.","PeriodicalId":171304,"journal":{"name":"2014 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126399345","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}

Also, there exists a series of special issues for VANETs urban area. Aiming to tackle these issues, many such routing protocols have been proposed in academia. In this paper, we present four important issues for city scenarios which not only strongly affect the performance of routing protocols, but also will be key factors to prompt us to redesign more suitable routing protocols. Those issues include intermittent connectivity, traffic light at intersections, three-dimensional and traffic accident city scenarios. Then we give a survey on recent intersection-based geographic routing protocols and explore how those issues impact the performance of these protocols. In order to better reflect the influence of these issues, we perform a simulation-based analysis. We evaluate the performance of the existing routing protocols including GPCR, GyTAR, STAR, and TDR in city scenarios with above issues. Simulation results prove that these scenarios affect the performance of routing protocol significantly. Finally, we put forward guidelines which are conductive for designing VANETs routing protocols.","PeriodicalId":171304,"journal":{"name":"2014 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123700214","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}

As a solution, we have developed a 3D Web-based Visualization Tool for VANET Simulations (WGL-VANET), which takes advantage of HTML5 and WebGL technologies to create a cross-platform, easy-to-use and flexible visualization tool for VANET simulations.

Although some scaling law-based results had already been obtained for VANETs to describe the general performance changing pattern when the total number of network nodes goes to infinity, they cannot be used directly to estimate the actual capacity of a communication pair or the entire network. To make up with this disadvantage, a interference-based capacity analysis is finished in this paper for the VANETs scenario. For representing the unique constraint of inter-vehicle distance, which directly affects both the signal and interference power decaying, the car-following model is used to describe the vehicles' mobility feature. Based on that, a series of probability characteristics are derived for a general interfering scenario, which finally leads to the expected VANET capacity. We believe the new results obtained in this paper will provide useful guidelines for the deployment of future VANETs.","PeriodicalId":171304,"journal":{"name":"2014 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123476371","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 the charging infrastructure is shared in order to provide different services, the constraints imposed by the System Operator (SO) of the electric network must always be respected to guarantee the simultaneous operation of all the services provided. TeleWatt is an innovative EV charging infrastructure which is shared with the electric network deployed for the Public Lighting System (PLS). The first approach of this solution remained quite conservative, as the main scope was to prove that the PLS and the EV charging system could operate simultaneously. The present work proposes the adaptation of some well-known on-line scheduling policies to the infrastructure of TeleWatt, which is limited by the constraints of the PLS network. This allows to treat the charge of EVs as tasks and manage them according to different priorities. This work demonstrates how the performance of the system could be improved without any physical changes in the infrastructure, but just by the way that the resources are managed.","PeriodicalId":171304,"journal":{"name":"2014 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131718938","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 focus on the exploitation of vehicle-to-vehicle communications to deliver part of the data produced on board to the road side units (RSUs) deployed in the scenario, avoiding, as much as possible, the adoption of the cellular network. Specifically, we propose a novel routing algorithm that is based on the greedy forwarding approach and uses virtual RSUs to overcome the problem of the local minima. The proposed algorithm allows data to be redirected through optimized directions with limited amount of added information. In addition, system optimization can be performed via software and the choice of the RSU positions becomes less critical. The effectiveness of the proposed algorithm is demonstrated through simulations performed using realistic vehicular traces in two European cities, showing that the proposed solution increases the amount of data transmitted through the vehicular networks.","PeriodicalId":171304,"journal":{"name":"2014 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115044873","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}
