摘要

在本文中，我们提出了一种新的时间稳定的地球广播协议，称为iDTSG，用于车辆高速公路网络的碰撞后通知。iDTSG是对现有DTSG协议的改进。基于ns-3仿真的真实信道模型和车辆移动模型表明，在低车辆密度下，iDTSG几乎实现了与DTSG相似的100%的传输率，但重发数据包的成本要低得多。结果还表明，iDTSG中使用的车辆间距动态估计具有良好的性能。

iDTSG time-stable geocast for post crash notification in vehicular highway networks

In this paper, we propose a new time-stable geocast protocol, called iDTSG, for post crash notification in vehicular highway networks. iDTSG is an improvement of the existing DTSG protocol. From ns-3 simulation with realistic channel model and vehicle mobility model, iDTSG achieves almost 100% delivery ratio, similar to DTSG, but at a much lower cost of rebroadcast packets, in low vehicle densities. The results also show that the dynamic estimation of the inter-veicle spacing used in iDTSG performs well.
