In the scenario of vehicular networks, due to connectivity transitory and throughput degradation caused by high vehicle mobility, traditional privacy-preserving methods such as k-anonymity are not sufficient. As an effort toward this issue, we propose a framework which enhances the privacy of LBS by actively caching in the wireless vehicular network scenario. The scheme is designed under the dedicated short-range communication (DSRC) standard, with three original contributions. First, a point of interest (POI) query probability model for in-vehicle users is defined, considering the spatial relationship between the current location and the queried location.
