c++ - About assining two different application to 50 nodes randomly in omnetpp.ini

Question

I am using VEINS 4a2 and I have two different application eg. one normal application from TraciDemo11.cc and another one I modified it. Is it possible to assign the two different applications to 50 nodes randomly. Eg. from *.node[5..20].applType = "TraCI" and "Modified traci" ? so that in each simulation run each nodes have different application running.

Thank you.

Answer 1

?: 运算符可用于将 Appl1 分配给 50% 的节点：

**.applType = uniform(0,1) < 0.5 ? "Appl1" : "Appl2"

这将为每次运行创建不同的分配，因为每次运行都会为随机函数接收不同的种子。

从 Veins 4.3 开始，您可以为不同的 SUMO 车辆类型分配不同的 OMNeT++ 模块类型。因此，如果您升级到 Veins 4.3 并将 SUMO 配置为使用随机车辆类型，您可以达到预期的效果。
