基于车辆机会网络的路由算法的研究
基于车辆机会网络的路由算法的研究(任务书,开题报告,外文翻译,论文12000字)
摘 要
车载自组织网络VANET(Vehicular Ad Hoc Network)是智能交通系统不可或缺的一部分，由于车辆节点的行驶速度较快，所以网络的拓扑会不断的改变、通信链接不太稳定。在车辆机会网络中，信息的传递是通过车辆节点间相遇时的数据交换来实现的，这些交换的数据包含着许多信息，如节点的速度和位置。
在大多数关于车载网络的研究中，机会路由算法及其相关研究占了很大一部分比例，这些路由算法的主要实现目标是为信息的传输选择合适的中继车辆节点，从而在最短时间内完成信息的有效传输。
本文首先主要通过ONE(Opportunistic Network Environment)仿真平台对车辆机会网络完成网络系统建模，然后对车辆机会网络中几个经典路由算法进行研究，接着设置相关参数建立不同的车辆网络模拟场景，最后在仿真平台中，针对建模的车辆机会网络场景完成对经典路由算法的仿真，通过生成报告得到网络的递交率，信息延时和网络开销这三个性能指标，并综合分析这三个指标来判断几个经典机会路由算法的优劣性。

Abstract
The vehicle auto organization network VANET (Vehicular Ad Hoc Network) is an indispensable part of the intelligent transportation system. As the speed of vehicle nodes is faster, the topology of the network will be constantly changed and the communication links are not stable. In the vehicle opportunity network, the transmission of information is realized by the exchange of data when the vehicle nodes meet, and the data of these exchanges contain a lot of information, such as the speed and location of the nodes.
In most research on the vehicle network, the opportunity routing algorithm and its related research account for a large proportion. The main goal of these routing algorithms is to select the appropriate relay vehicle nodes for the transmission of information, so that the effective transmission of information is completed in the shortest time.
In this paper, ONE (Opportunistic Network Environment) simulation platform is used to model the network system of vehicle opportunity network, and then several classical routing algorithms in vehicle opportunity network are studied. Then the relevant parameters are set up to set up different vehicle network simulation fields. Finally, in the simulation platform, the model is modeled. The vehicle opportunity network scene completes the simulation of the classic routing algorithm, and obtains three performance indexes of the network delivery rate, information delay and network overhead through the generation of reports, and analyzes the three indicators to judge the advantages and disadvantages of several classic opportunity routing algorithms.
Key Words：VANET; ONE simulation platform; classical opportunistic routing algorithm; performance index
