This paper studies the movement characteristics of the vehicle node in vehicular ad hoc network and analyzes the existing opportunistic network routing algorithms. On the premise of low computational complexity and low storage space occupancy, a Social Attribute Aware-based Vehicular Opportunistic Routing Protocol (SAVOR) is proposed, which consists of a social attribute formation mechanism, a community formation and maintenance mechanism and a data forwarding mechanism. Its work flow mainly includes community initialization stage, community maintenance stage and data forwarding stage. The simulation results show that SAVOR protocol effectively improves the success rate of packet delivery, reduces a large number of invalid packets forwarding, and reduces the network overhead in VANET. It can achieve efficient directional information delivery, which is suitable for scenarios such as commercial information advertising.
