Abstract

Various aspects of the present disclosure relate to vehicle-to-vehicle (V2V) data sharing. The sensor data collected from each vehicle may be divided into common information and detailed information. The common information is broadcasted to every other nearby vehicle. Based on the received common information other vehicles may express interest in some particular detailed information. Unicast and/or multicast sessions may be set up to share the detailed information with the interested vehicles.
