In this paper, we discuss scalable content-oriented routing that enables storing, sharing and searching data totally within the VANET. We introduce a proactive content discovery scheme, Hierarchical Bloom-Filter Routing (HBFR), to tackle mobility, large population and rich content challenges of VANETs. HBFR is compared to the popular ICN reactive content discovery scheme in practical VANET scenarios. The results show that HBFR suits non-sharable data services, while reactive ICN inspired content discovery works well with popular sharable data. We suggest a hybrid approach that adaptively utilizes proactive and reactive schemes for time-sensitive data in ICN VANET.
