摘要：
Adapting the frequently changed topology is the main task of data delivery in vehicular ad hoc networks. Making advantage of the characteristics that the mobility patterns and positions of vehicles are predicable, this paper presents an improved dynamic hop choosing mechanism for data delivery. It exploits predicting the positions and mobility patterns of vehicles, and also takes into account the vehicular traffic density. Accordingly, the next hop chosen by the proposed strategy is seldom out of reach even if the topology is quickly changed. Simulation results show that our approach improves the packet delivery ratio and reduces the network latency when compared with state of the art protocols. © 2017 Totem Publisher, Inc.
