摘要:  

摘要: 研究车辆网络的邻居位置获取问题,提出一种实时的邻居位置获取协议RNP。在RNP中,时间被分为一个个带时槽的时间帧。为了实现实时的邻居位置获取,RNP采取自适应的消息发送策略。通过理论分析,优化RNP的各个参数。基于真实车辆行驶数据的仿真实验表明,RNP优于其它方法。

Abstract:  

 Abstract:  The problem of neighbor position acquisition in vehicular networks is investigated. A realtime protocol called RNP for neighbor position acquisition is proposed. In RNP, time is divided into frames with some time slots. To achieve realtime neighbor position acquisition, RNP adopts an adaptive message transmission strategy. Based on an analytical framework, every parameter of RNP is optimized. Real tracedriven simulations are conducted. Performance results demonstrate that, RNP outperforms other alternative protocols.
