摘要：
针对移动自组织网络在车-车间无线通信系统的应用问题，提出一种简单有效的蒙特卡洛仿真模型。通过网络仿真器NS-2构建单向均匀交通流和带激波交通流的通信场景，采用计算信息传递吞吐量和平均端到端的方法延迟来评价车-车间通信网络的性能。仿真结果表明，与连通性模型相比，该方法可得到良好的评估效果。

Abstract:
Inter-Vehicle Communication(IVC) based on mobile Ad hoc networks draws increasing research interests in recent years. This paper proposes an efficient Monte Carlo simulation model and builds unidirectional uniform traffic flow and dynamic traffic flow with shockwave scenarios in Network Simulator 2(NS-2). Through simulation, the throughput and end-to-end delay are used to evaluate the performance of IVC systems. The simulation indicates that reasonable results are got compared with the connectivity model.
