Content-Based Download Cooperation Scheme in VANET: A Brief Review
View through CrossRef
The existence of a content-based download cooperation scheme in intermittently connected VANET not only satisfies the needs of vehicle users for security information services, but also facilitates the implementation of network value-added services. It enables users to download large amount of data files or watch online video in the driving vehicle, and so on. Meanwhile, the performance index of VANET is improved, such as increase downloaded throughput and spectral efficiency, reduce the data transmission delay and complexity of cooperation scheme, etc. Although there are many researches on the current cooperation schemes, but they are short of a systematic review. Therefore, the cooperative communication schemes in VANET will be divided into three categories. The cooperation schemes are introduced in detail in the cooperation conditions, communication modes and cooperative strategies, respectively. Based on the above classification, this paper focuses on the study, comparison and analysis of the latest cooperative communication schemes from wireless access technology, cooperation direction, download data volume, etc. In addition, some problems and future research directions of cooperation scheme in the current VANET are proposed.
