| 摘要: |
| 提出了一种基于分布式实时信息的车载自组织网络路由协议(distributed real-time information basedrouting protocol,简称DRIP).网络中,车辆基于提出的分布式实时路段延时估计机制(distributed real-time delayevaluation scheme,简称DRES)获取各路段网络状态的实时信息,车辆根据对各路段网络延时的实时估计,采用DRIP协议,保证了数据的有效传递.与现有协议相比,DRIP 在最低限度消耗资源的情况下,具有实时性和高效性的特点.通过仿真实验对比现有协议,验证了DRIP 在性能上的优越性. |

| Abstract: |
| This paper proposes a Distributed Real-time Information based Routing Protocol in vehicular ad-hoc networks (DRIP). Based on the proposed Distributed Real-time Delay Evaluation Scheme (DRES), vehicles obtain the real-time information for the network status of each road, and according to the delay evaluation of each road, vehicles use DRIP for an effective data delivery. Compared with existing protocols, DRIP has the characters of being effective and having a low resource consumption rate. The simulation results indicate that DRIP performs well. |
