Geographic Routing Based on Social Dynamic Features Aware in Vehicle Social Network

Vehicular ad-hoc network has the characteristics of Delay Tolerant Network and social network. In this background, we take the social attributes of Delay Tolerant Network as starting point and study the macroscopic dynamic features, micro dynamic features and dynamic contact features of vehicles. In this paper, we proposed a geographic multicast routing based on social dynamic features aware which solves messages transmission problems in vehicular ad hoc network. Different from the existing mobility-aware geocast algorithm, our algorithm takes into account not only the relationships between vehicles mobility and geographical location, but also the contact features between vehicles and destination areas. Finally, it is proved that our algorithm is superior to the existing mobility-aware geocast algorithm in term of delivery rate, network overhead and average delay by the real mobile data model simulation in large vehicular ad-hoc network. The results prove the effectiveness of our algorithm, and the routing protocol we proposed is suited for large urban vehicular ad hoc networks.
