Over the last couple of years, traditional VANET (Vehicular Ad HocNETwork) evolved into VANET-based clouds. From the VANET standpoint, applicationsbecame richer by virtue of the boom in automotive telematics and infotainmenttechnologies. Nevertheless, the research community and industries are concernedabout the under-utilization of rich computation, communication, and storage resourcesin middle and high-end vehicles. This phenomenon became the driving force for thebirth of VANET-based clouds. In this paper, we envision a novel application layer ofVANET-based clouds based on the cooperation of the moving cars on the road, calledCaaS (Cooperation as a Service). CaaS is divided into TIaaS (Traffic Information as aService), WaaS (Warning as a Service), and IfaaS (Infotainment as a Service). Note,however, that this work focuses only on TIaaS and WaaS. TIaaS provides vehicularnodes, more precisely subscribers, with the fine-grained traffic information constructedby CDM (Cloud Decision Module) as a result of the cooperation of the vehicles on theroads in the form of mobility vectors. On the other hand, WaaS provides subscriberswith potential warning messages in case of hazard situations on the road. Communicationbetween the cloud infrastructure and the vehicles is done through GTs (GatewayTerminals), whereas GTs are physically realized through RSUs (Road-Side Units) andvehicles with 4G Internet access. These GTs forward the coarse-grained cooperationfrom vehicles to cloud and fine-grained traffic information and warnings from cloud tovehicles (subscribers) in a secure, privacy-aware fashion. In our proposed scheme,privacy is conditionally preserved wherein the location and the identity of thecooperators are preserved by leveraging the modified location-based encryption and, incase of any dispute, the node is subject to revocation. To the best of our knowledge,our proposed scheme is the first effort to offshore the extended traffic view constructionfunction and warning messages dissemination function to the cloud.
Abstract
Over the last couple of years, traditional VANET (Vehicular Ad HocNETwork) evolved into VANET-based clouds. From the VANET standpoint, applicationsbecame richer by virtue of the boom in automotive telematics and infotainmenttechnologies. Nevertheless, the research community and industries are concernedabout the under-utilization of rich computation, communication, and storage resourcesin middle and high-end vehicles. This phenomenon became the driving force for thebirth of VANET-based clouds. In this paper, we envision a novel application layer ofVANET-based clouds based on the cooperation of the moving cars on the road, calledCaaS (Cooperation as a Service). CaaS is divided into TIaaS (Traffic Information as aService), WaaS (Warning as a Service), and IfaaS (Infotainment as a Service). Note,however, that this work focuses only on TIaaS and WaaS. TIaaS provides vehicularnodes, more precisely subscribers, with the fine-grained traffic information constructedby CDM (Cloud Decision Module) as a result of the cooperation of the vehicles on theroads in the form of mobility vectors. On the other hand, WaaS provides subscriberswith potential warning messages in case of hazard situations on the road.
