【摘要】 基于车联网的特征,设计一个合适的NDN缓存策略可以在很大程度上提升车联网的性能。目前,已经有大量的文献研究了NDN的缓存策略。通过对已有文献的充分调研,首先对NDN缓存策略在车联网环境下应用的必要性进行了分析,随后列举了NDN缓存策略在车联网中所面临的挑战,接下来阐述了现有的缓存策略和缓存替换策略。最后,对若干有代表性的缓存策略和缓存替换策略进行了对比。更多还原

【Abstract】 Based on the characteristics of the internet of vehicles, designing a suitable NDN cache strategy can greatly improve the performance of the internet of vehicles. In fact, many caching strategies have been proposed in NDN before. Firstly, the necessity of applying NDN cache strategy in the internet of vehicles environment was analyzed by thorough studying to the previous researches on NDN caching strategy. After that, the challenges faced by the NDN caching strategy in the internet of vehicles were proposed. Next, a deep survey to the previous works on caching and cache replacement in NDN was illustrated. Finally, a comparison between the caching strategies as well as cache replacement schemes was introduced.更多还原
