我想使用静脉,在OMNeT++网络模拟器和SUMO道路交通模拟器之间进行联合模拟。

Veins 有sumo-launchd守护程序(用 Python 编写),旨在在后台运行,监听传入的请求。在每个传入连接上,它接收 XML 格式的模拟设置,然后启动一个单独的 SUMO 实例并代理 OMNeT++ 和 SUMO 之间的请求。

当我在终端中运行sumo-launchd.py(在打开 OMNet++ 并开始模拟之后)时,我得到以下问题,我认为这是与 Python 相关的。

bluemix@blueMix:~/SUMO/veins-2.1/examples/veins$ python /home/bluemix/SUMO/veins-2.1/sumo-launchd.py -vv -c /home/bluemix/SUMO/sumo-0.19.0/bin/sumo

以及来自 OMNeT++ 控制台的信息:

我用谷歌搜索 ( 1 , 2 ) 问题,但与我的不完全相同。提前致谢。

这是静脉所有者 ( Christoph Sommer ) 的回复:

这应该适用于所有当前版本的 SUMO。请注意,它尚未接受广泛的测试,所以请让我知道任何问题。

最好的,

您需要使用终端中的以下行来启动相扑:

sumo-launchd.py -vv -c sumo-gui

并从中运行omnetpp.ini文件omnet++
