NDN-VANET has been developed to enable robust end-to-end communication in VANETs, which are vulnerable networks due to the mobility of vehicles. The NDN functionality enables fast content delivery through network caching and content-centric communication. However, standard NDN does not incorporate any mechanism for priority control based on the significance of the requested data. This paper proposes a new caching method that utilizes spatial locality, based on context awareness of vehicular itineraries. Performance evaluation results confirm that the proposed method effectively improves the cache hit ratio enabling fast delivery of emergency content.
