Vehicle Ad-hoc Network (VANET) is a kind of Mobile Ad-hoc Network (MANET) that establishes wireless connection between cars. In VANETs and MANETs, the topology of the network changes very often, therefore implementation of efficient routing protocols is very important problem. In MANETs, the Random Waypoint (RW) model is used as a simulation model for generating node mobility pattern. On the other hand, in VANETs, the mobility patterns of nodes is restricted along the roads, and is affected by the movement of neighbour nodes. In this paper, we present a simulation system for VANET called CAVENET (Cellular Automaton based VEhicular NETwork). In CAVENET, the mobility patterns of nodes are generated by an 1-dimensional cellular automata. We improved CAVENET and implemented some routing protocols. We investigated the performance of the implemented routing protocols by CAVENET. The simulation results have shown that DYMO protocol has better performance than AODV and OLSR protocols.

CAVENET的实现及其在车载网络中用于AODV，OLSR和DYMO协议性能评估的用途

车辆自组织网络（VANET）是一种在汽车之间建立无线连接的移动自组织网络（MANET）。在VANET和MANET中，网络的拓扑结构经常变化，因此有效的路由协议的实现是非常重要的问题。在MANET中，随机航点（RW）模型用作生成节点移动性模式的仿真模型。另一方面，在VANET中，节点的移动性模式沿道路受到限制，并且受相邻节点的移动的影响。在本文中，我们提出了一种用于VANET的仿真系统，称为CAVENET（基于蜂窝自动机的车载网络）。在CAVENET中，节点的移动性模式是由一维元胞自动机生成的。我们改进了CAVENET并实现了一些路由协议。我们调查了CAVENET实施的路由协议的性能。仿真结果表明，DYMO协议的性能优于AODV和OLSR协议。
