Multimedia Services in Cloud-Based Vehicular Networks

Abstract

Research into the requirements for mobile services has seen a growing interest in the fields of cloud technology and vehicular applications. Integrating cloud computing and storage with vehicles is a way to increase accessibility to multimedia services, and inspire myriad potential applications and research topics. This paper presents an overview of the characteristics of cloud computing, IEEE IntEllIgEnt transportatIon systEms magazInE • 63 • fall 2015 and introduces the basic concepts of vehicular networks. An architecture for multimedia cloud computing is proposed to suit subscription service mechanisms. The tendency to equip vehicles with advanced and embedded devices such as diverse sensors increases the capabilities of vehicles to provide computation and collection of multimedia content in the form of the vehicular network. Then, the taxonomy of cloud-based vehicular networks is addressed from the standpoint of the service relationship between the cloud computing and vehicular networks. In this paper, we identify the main considerations and challenges for cloud based vehicular networks regarding multimedia services, and propose potential research directions to make multimedia services achievable. More specifically, we quantitatively evaluate the performance metrics of these researches. For example, in the proposed broadcast storm mitigation scheme for vehicular networks, the packet delivery ratio and the normalized throughput can both achieve about 90%, making the proposed scheme a useful candidate for multimedia data exchange. Moreover, in the video uplinking scenarios, the proposed scheme is favorably compared with two well-known schedulers, M-LWDF and EXP, with the performance much closer to the optimum.

Cloud Computing in VANETs: Architecture, Taxonomy, and Challenges

“…The application system is defined using the suitability in the cloud environment for vehicular communications including VuC, VCC, and HVC. The summary and comparative analysis of the application based developments in CC-V suggest that MSCVN [64] is more practical application concept with greater user friendly services. The implementation plan of MSCVN is widely acceptable in CC-V environments.…”

“…Multimedia services have become one of the major research area of interest in both cloud computing and VANETs because of its relevance in both infotainment and safety. Thus, a Multimedia Services in Cloud-based Vehicular Networks (MSCVN) has been employed to integrate cloud computing and storage with vehicles, in order to increase accessibility to multimedia services [64]. Different systems including LTE system for network access, and multimedia cloud computing system have been suggested.…”
