omnet++

I am using OMNet++ to simulate a wireless network. The scenario is : "sensor nodes send sensory data to some nodes (called RN)(send to the nearest RN). and some mobile elements collect data from these points." sensors distribute uniform in field and position of RNs are determined.also MEs follow BonnMobility with predefined path. I'm using omnet 5.4 with inet 3.6. numHost=500 ** numME=5 ** numRN=50 NED file: network MyNet { parameters: int numHost; int numME; int numRN; string hostType = default("WirelessHost"); string mediumType = default("IdealRadioMedium"); @display("bgb=600,600;bgu=m");

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

How can I run the simulation with different configurations? I am using omnet++ version 4.6 . My omnetpp.ini file looks as below : [General] [Config Dcn2] network = Dcn2 # leaf switch #**.down_port = 2 **.up_port = 16 #12 # 4 # spine switch **.port = 28 # 20 #2048 # crossconnect **.cross_down_port = 28 # 20 #2048 **.cross_up_port = 28 # 20 #2048 # to set destination of packet **.number_leaf_switch = 28 # 20 #2048 # link speed #**.switch_switch_link_speed = 40 Mbps **.interArrivalTime = ${exponential(.0001),exponential(0.0002),exponential(0.0003)} **.batch_length = 10 **.buffer_length = 10 sim

I want to modify some parameters of element's .ini file in OMNeT++, say a node's transmission rate, during the simulation run, e.g. when a node receives some control message. I found information saying that it's possible to somehow loop the configuration stated as: some_variable = ${ several values }, but there are no conditional clauses in .ini files and no way to pass to those files any data from C++ functions (as far as I'm concerned). I use INET, but maybe some other models' users already bothered with such a problem. While you can certainly manually change volatile parameters , OMNeT++
