veins

I have read a bunch of posts on SO regarding the computation of end-to-end delay in Veins, but have not found an answer to be fulfilling in explaining why the delay is seemingly too low. I am using: Veins 4.7 Sumo 0.32.0 Omnetpp 5.3 Channel switching is turned off. I have the following code, sending a message from the transmitting node: if(sendMessage) { WaveShortMessage* wsm = new WaveShortMessage(); sendDown(wsm); } The receiving node computes the delay using the wsm creation time, but I have also tried setting the timestamp on the transmitting side. The result is the same. simtime_t delay =

I want to transmit a given car's vehicular data such as it's vType , instantaneous speed and position to a RSU in a scenario in Veins. How can I obtain the data from SUMO and send it through MiXiM methods to an RSU node? user4786271 To achieve your goal you have to use the TraCIMobility component of Veins . You can do that by first getting a pointer to that component in the initialize() method of your node cModule *tmpMobility = getParentModule()->getSubmodule("veinsmobility"); mobility = dynamic_cast<Veins::TraCIMobility*>(tmpMobility); ASSERT(mobility); Once you have the mobility component

Is it possible to calculate(get) direction of vehicle in Veins(via TraCIMobility)? I want to know if two vehicles are traveling in opposing directions or not. I think I can do that via getAngleRad() method (if they are moving in the same direction they fall in the same quadrant and if moving opposite they are in opposite quadrants), but I am not sure if its correct. (Sub-Question: Also, what are the exact values that getAngleRad() would return for each quadrant?) Christoph Sommer You are correct: getAngleRad() returns the vehicle's heading in radians (from -pi up to, but excluding, +pi ). A

If I know the coordinates at which RSUs will be placed in SUMO, How do I convert it to coordinates of omnet++? I know that SUMO has a different coordinate system than omnet. Should I convert it offline (before starting simulation) using the equations used in the internal function "traci2omnet"? I tried this but seems inaccurate. I tried also to create a junction at the position of the RSU in sumo, retrieve the location of this junction in omnet then place the RSU at the same coordinates. But is it possible to do such scenario while running the simulatin(during initialization for example)? Does

I want to access the command interface of TraCI from the application layer of RSU model in Veins Source for OMNet++. But I am unable to find so. Can anyone please help me do so? Please note that I am not having TraciMobility as parent module in case of RSU Node. It is having only the BaseMobility which is what I want it to have. Now I want to access the command interface so that this RSU can perform the sumo instructions like change traffic light and get induction loop data. Veins 4.3 provides a TraCIScenarioManagerAccess helper class, which can be used to quickly get access to the class

did the installation of the veins according to the tutorial of the site ( http://veins.car2x.org/tutorial/ ) using the operating system windows 10, but in the last step, when executing the omnetpp.ini of the example of the veins the code compiles but the execution in qtnev gives the following error: Help me please Cannot evaluate parameter ‘headerLength’: (omnetpp::cDoubleParlmpl)headerLength: Cannot cast from type double to integer – in module (Mac1609_4) RSUExampleScenario.rsu[0].nic.mac1609_4 (id=12), during network initialization This was introduced in a recent version of OMNeT++, which no
