Question

我想在启动仿真工作片刻时模拟一个简单的场景，然后出现以下错误：

Unable to use SimpleObstacleShadowing: No obstacles have been added --     in module (Veins::ObstacleControl) myNet.obstacles (id=2), at t=2.90795546076s, event #103

config.xml文件中的SimpleObstacleShadowing模型：

<AnalogueModel type="SimpleObstacleShadowing">
<parameter name="carrierFrequency" type="double" value="5.890e+9"/> 
 <obstacles>
  <type id="building" db-per-cut="9" db-per-meter="0.4" />
 </obstacles>
</AnalogueModel>

Answer 1

在这种情况下，您没有任何障碍。尝试删除行

*.obstacles.debug = false
*.obstacles.obstacles = xmldoc("helloConfig.xml",       "//AnalogueModel[@type='SimpleObstacleShadowing']/obstacles")

，然后再次运行仿真。在user documentation中可以找到创建多边形的语法。

根据config.xml的设置，您必须将多边形的type设置为building
