摘　　要：针对车载网V ANET(Vehicular Ad hoc Network)中的广播策略,提出新颖的自动分发方案(Autonomic Dissemination Method,ADM)。通过ADM传输消息,自适应网络的密度和消息的优先级变化。在实施A DM过程中,采用两个步骤:离线优化过程和在线适应网络特性。仿真结果表明,提出的A DM方案在消息传递率、传输时延和干扰方面得到提高。Aiming at the broadcasting used in Vehicular Ad hoc Network（VANET）,this paper introduces a novel autonomic dissemination method（ADM） which delivers messages in accordance with given priority and density levels. The proposed approach is based on two steps：an offline optimization process and an online adaptation to the network characteristics. Simulation results show that the ADM can increase the efficiency of the broadcasting process in terms of message delivery ratio, latency and interference re- duction.
