Shape-Unconstrained Privacy-Preserving Range Query for Fog Computing Supported Vehicular Networks Using Image

For Location-Based Service (LBS) in vehicular networks, there is a trend to leverage fog nodes to provide low-latency range query services. However, traditional coordinate-centric range query frameworks face performance and security challenges when they are deployed at fog nodes. First, traditional frameworks employ coordinate computation to search targets, thus they cannot support highly irregular areas at network edges. Second, existing...
