摘要:
针对目前对车载自组织网络的仿真研究存在采用的交通模型不能描述真实交通特性的不足,从车载自组织网络仿真应用的角度研究了随机游走模型、随机驻留点模型和随机方向移动模型等三种随机移动模型与参考点群移动模型、曼哈顿移动模型对仿真测试结果的影响.首先,对随机移动模型、参考点群移动模型与曼哈顿移动模型等五种常见车辆移动模型进行了性能分析和对比;然后,针对仿真测试需求,构建了一种基于Veins的车联网仿真平台;最后,基于构建的仿真平台测试了不同车辆移动模型在按需平面距离向量路由协议AODV和Bypass-AODV协议下的性能差异.仿真结果显示,在给定的场景条件下,参考点群移动模型RPGM能够建立更多长度较长的通信连接,且具有相对更高、更稳定的有效网络吞吐量,能够更直观地反映不同路由协议的性能.
Abstract:
Aiming at the problem that the adopted traffic model couldn’t describe the real traffic characteristics in the current simulation of vehicular ad hoc networks (VANETs),we study the influence of the reference point group mobility model (RPGM),the Manhattan mobility model (MAN) and three random mobile models like random walk mobility model (RWMM),random waypoint mobility model (RWP) and the random direction mobility model (RDM) on the simulation test results from the perspective of vehicular ad hoc network simulation. First,the performance analysis and comparison of the above five vehicle moving models are carried out. Then,in view of the requirements of the simulation test,a simulation platform of VANETs based on Veins is constructed.Finally,the performance differences of different vehicle mobile models under two protocols,AODV and Bypass-AODV,are tested. The simulation shows that RPGM can establish more long communication connections,and has a relatively higher and more stable effective network throughput,which can more directly reflect the performance of different routing protocols under given scenario conditions.
