车载自组织网络是一种新兴的、极具挑战性的移动的自组织网络。预计VANETM将大规模部署在即将推出的车辆中，因为它们的使用可以提高驾驶安全性，并使新形式的车辆间通信成为可能。由于它们具有高移动性和动态拓扑变化的特点，因此需要对它们进行拥塞控制。在本文中，我们分析了在VANET的TCP流量。我们研究和比较了TCP Vegas和TCP New里诺的DYMO协议的Good put，同时考虑了拥塞窗口，慢启动阈值和序列号随时间的变化。仿真结果表明，在该VANET场景下，TCP New里诺协议的性能优于TCP Vegas协议.
Vehicular Ad-hoc Networks (VANETs) represent a rapidly emerging, particularly challenging class of Mobile Ad-hoc Networks (MANETs). VANETs are expected to be massively deployed in upcoming vehicles, because their use can improve the safety of driving and makes new forms of inter-vehicle communications possible as well. Because they are characterized of high mobility and dynamic topology change, congestion control should be performed in such networks. In this paper, we analyze the TCP traffic in a VANET. We investigate and compare the Good put of DYMO Protocol for TCP Vegas and TCP New Reno considering also the congestion window, slow-start threshold and sequence number versus time. The simulation results show that in this VANET scenario, TCP New Reno performs better than TCP Vegas.
