车载自组网（VANET）是一种在汽车之间建立无线连接的移动的自组网（MANET）。在广域网和城域网中，网络的拓扑结构经常变化，因此实现高效的路由协议是非常重要的问题。在移动自组网中，随机路径点（RW）模型被用作生成节点移动模式的仿真模型。另一方面，在VANCITY中，节点的移动模式被限制在沿着道路上，并且受到相邻节点的移动的影响。本文提出了一种基于元胞自动机的车载自组网仿真系统CAVENET（Cellular Automaton based VEhicular NETwork）。在CAVENET中，节点的移动模式由一维元胞自动机生成。我们改进了CAVENET并实现了一些路由协议。我们研究了CAVENET实现的路由协议的性能。仿真结果表明，DYMO协议的性能优于AODV和OLSR协议。
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.
