I want to implement the UDPBASICBurst app in Veins, but I am facing problems. I have done as follows but I don't know if I am correct. Can anybody put light on this matter?
import inet.applications.udpapp.UDPBasicBurst;
import org.car2x.veins.base.modules.*;
import org.car2x.veins.modules.nic.Nic80211p;
....
udpBasicBurst: UDPBasicBurst {
#display("p=130,56");
}`enter code here`
connections allowunconnected:
nic.upperLayerOut --> appl.lowerLayerIn;
nic.upperLayerIn <-- appl.lowerLayerOut;
nic.upperControlOut --> appl.lowerControlIn;
nic.upperControlIn <-- appl.lowerControlOut;
veinsradioIn --> nic.radioIn;
udpBasicBurst.udpOut --> nic.upperControlIn;
udpBasicBurst.udpIn <-- nic.upperControlOut;
}
import inet.applications.udpapp.UDPBasicBurst;
import org.car2x.veins.base.modules.*;
import org.car2x.veins.modules.nic.Nic80211p;
module Car
{
parameters:
string applType; //type of the application layer
string nicType = default("Nic80211p"); // type of network interface card
string veinsmobilityType; //type of the mobility module
gates:
input veinsradioIn; // gate for sendDirect
submodules:
appl: <applType> like org.car2x.veins.base.modules.IBaseApplLayer {
parameters:
#display("p=60,50");
}
nic: <nicType> like org.car2x.veins.modules.nic.INic80211p {
parameters:
#display("p=60,166");
}
veinsmobility: <veinsmobilityType> like org.car2x.veins.base.modules.IMobility {
parameters:
#display("p=130,172;i=block/cogwheel");
}
udpBasicBurst: UDPBasicBurst {
#display("p=130,56");
}
connections allowunconnected:
nic.upperLayerOut --> appl.lowerLayerIn;
nic.upperLayerIn <-- appl.lowerLayerOut;
nic.upperControlOut --> appl.lowerControlIn;
nic.upperControlIn <-- appl.lowerControlOut;
veinsradioIn --> nic.radioIn;
udpBasicBurst.udpOut --> nic.upperControlIn;
udpBasicBurst.udpIn <-- nic.upperControlOut;
}
You are importing both inet.applications.udpapp.UDPBasicBurst and org.car2x.veins.modules.nic.Nic80211p in the same module. This will likely not work the way you hope:
Simply speaking, modules in the inet.* namespace only expect to exchange messages with other modules from this namespace. Up to and including Veins 4a2, the same goes for modules in the org.car2x.veins.* namespace - with one notable exception: The Veins 4a2 TraCIScenarioManager will check if an instantiated module uses an inet 2.3.0 TraCIMobility module as their mobility submodule. If it does, it will move the module accordingly.
This allows you to use Veins 4a2 mobility in INET 2.3.0 hosts.

I have the following simple module
PythonConnection.ned
simple PythonConnection {
#class(PythonConnection);
// my code
}
PythonConnection.h
#include <omnetpp.h>
class PythonConnection : public omnetpp::cSimpleModule {
//my code
}
PythonConnection.cc
#include "PythonConnection.h"
Define_Module(PythonConnection);
void PythonConnection::initialize() {
//my code
}
all of them are located in the same directory.
I am importing this simple module in circles.ned file
package circles;
import PythonConnection;
network circles
{
submodules:
python_connection: PythonConnection;
}
But I do not understand why I keep getting
A runtime error occurred:
Class "PythonConnection" not found -- perhaps its code was not linked in, or the class wasn't registered with Register_Class(), or in the case of modules and channels, with Define_Module()/Define_Channel() -- in module (omnetpp::cModule) circles (id=1), during network setup
when I launch the program. Could somebody help?
My problem was that I have created General project. To make it work, OMNeT++ Project is required.
I require an approach that whenever the one of host nodes in the following NED scenario receives a message or packet, a function like handlemessage is called. I want to extend a simple or compound module from AdhocHost in the Inet, for example, called Txc1 with all AdhocHost properties. Is it even possible to extend this mentioned simple module outside the Inet directories and subdirectories?
How can I reach this goal? How to code it in NED file, h, and cc files of this module?
My NED file for the network is as:
import inet.environment.common.PhysicalEnvironment;
import inet.networklayer.configurator.ipv4.Ipv4NetworkConfigurator;
import inet.node.inet.AdhocHost;
import inet.physicallayer.ieee80211.packetlevel.Ieee80211DimensionalRadioMedium;
import inet.visualizer.integrated.IntegratedVisualizer;
network Net80211
{
parameters:
int numHosts;
#display("bgb=600,400;bgi=background/terrain");
#signal[packetSent](type=inet::Packet);
#signal[packetReceived](type=inet::Packet);
#statistic[packetSent](title="packets sent"; source=packetSent; record=count,"sum(packetBytes)","vector(packetBytes)"; interpolationmode=none);
#statistic[packetReceived](title="packets received"; source=packetReceived; record=count,"sum(packetBytes)","vector(packetBytes)"; interpolationmode=none);
#statistic[throughput](title="throughput"; unit=bps; source="throughput(packetReceived)"; record=vector);
#signal[reqStreamBytes](type=long);
#statistic[reqStreamBytes](title="requested stream bytes"; record=count,sum,vector; interpolationmode=none);
#statistic[rcvdPkLifetime](title="received packet lifetime"; source="dataAge(packetReceived)"; unit=s; record=stats,vector; interpolationmode=none);
#statistic[rcvdPkSeqNo](title="received packet sequence number"; source="appPkSeqNo(packetReceived)"; record=vector; interpolationmode=none);
submodules:
visualizer: IntegratedVisualizer {
parameters:
#display("p=640,15;is=s");
}
configurator: Ipv4NetworkConfigurator {
parameters:
#display("p=640,112;is=s");
}
radioMedium: Ieee80211DimensionalRadioMedium {
parameters:
#display("p=638,56;is=s");
}
host[numHosts]: AdhocHost {
parameters:
#display("r=,,#707070;p=300,200;is=s");
}
stModule: StModule {
#display("p=639,169;i=block/cogwheel;is=s");
}
globalListener: GlobalListener {
#display("p=67,128");
}
}
Notes:
stModule is a simple module, for writing results in the finish function.
As an approach, if a new module extends from AdhocHost and it is able to trigger its own handlemessage function, it is replaced instead of AdhocHost.
As my rule, that function should be defined at the network layer. It is better to have a similar function in the data link layer, too.
A similar and simple question is in A new module that inherit from AdhocHost in omnet++. Although I test this approach, it has a problem(not call handlemessage).
Thanks in advance
I want to make some VANET simulation using OMNeT++, Veins, SUMO.
I was rewrite some code in Veins example code "RSUExampleScenario".
RSUExampleScenario.ned
import org.car2x.veins.nodes.RSU;
import org.car2x.veins.nodes.Scenario;
network RSUExampleScenario extends Scenario
{
#display("bgb=800,800");
submodules:
rsu[1]: RSU
{
#display("p=150,140;i=veins/sign/yellowdiamond;is=vs");
}
rsu[2]: RSU
{
#display("p=180,140;i=veins/sign/yellowdiamond;is=vs");
}
}
But it still seems that the RSU has not been added. How can I add an RSU module?
I was found how to add RSU node in simulation. If you want to add two RSU node in your simulation, you can write code like below.
veins/examples/veins/omnetpp.ini
# RSU SETTINGS
*.rsu[0].mobility.x = 2000
*.rsu[0].mobility.y = 2000
*.rsu[0].mobility.z = 3
*.rsu[1].mobility.x = 2100
*.rsu[1].mobility.y = 2000
*.rsu[1].mobility.z = 3
veins/examples/veins/RSUExampleScenario.ned
submodules:
rsu[2]: RSU
{
#display("p=150,140;i=veins/sign/yellowdiamond;is=vs");
}
I have already declared Define_Module(veins:: TraCIDateDissemination) and go through with various suggestions provided but getting this error again. Any suggestion is welcome. please help.
How to register a new class (new application) in Omnet++
Error in module during network setup:
Class "simpleModule" not found in omnetpp
https://doc.omnetpp.org/omnetpp/manual/
In manual I checked -
7.12.3 Class Registration
You should also use the Register_Class() macro to register the new class. It is used by the createOne() factory function, which can create any object given the class name as a string. createOne() is used by the Envir library to implement omnetpp.ini options such as rng-class="..." or scheduler-class="...". (see Chapter [17])
But not able to understand. pls help.
A runtime error occurred:
Class "TraCIDataDissemination" not found -- perhaps its code was not linked in, or the class wasn't registered with Register_Class(), or in the case of modules and channels, with Define_Module()/Define_Channel() -- in module (omnetpp::cModule) RSUExampleScenario.node[0] (id=13), at t=1s, event #2

Iam trying to create simple wireless node for MANET network which can send messages to other nodes in range. Solutions implemented in INET also contains other layers like IP, transport, application which i dont need.
Iam new to omnet++ so iam struggling a bit. I was thinking of creating whole own node with RadioIn input, but i dont know how to implement only in range communication and i will also need node mobility.
Other solutions would be to use only Radiomedium from INET framework but i dont know how to do it.
Can someone please give me some begginer tips how to achieve my goal? As i said i simply need to create mobile host which can send a defined message to all other hosts in range.
EDIT: I tried to take IdealRadioMedium and create my simple module and connect to it. Here is the NED File.

When i run the simulation it asks for Interfacetable parameter which i dont know what to type there becuse i havent found it in traversing functioning code ( I had to add it because it throws error that is missing if its not as submodule). Now iam getting
getCointainingNode() node module not found it should have a property name networkNode for module WirelessC.interfaceTable in module .... durint network initialization
EDIT: I added networknode as parameter and now i got Module not found on path '.mobility' defined by par WirelessC.hostA.wlan[0].radio.antenna.Mobilitymodule in module inte::physicallayer:IsotropicAntenna during network initialization
I'd like to point you to the wireless tutorial for INET: https://omnetpp.org/doc/inet/api-current/tutorials/wireless/
It starts with exactly your problem. The only thing left, is to replace the standard UDP host with a host using no protocol at all, maybe even implementing your own. The whole wireless part is explained in the tutorial.
If you want to check the source files for the used modules you need to walk down the chain of dependency since every compound NED module will (at one point) contain simple modules implemented in C++.
E.g. the module which is responsible for distributing the signals is IdealRadioMedium using RadioMedium. Now you need to find the Node implementation directly communicating with this module.
Starting with the WirelessHost used in the tutorial the underlying modules are
StandardHost -> ApplicationLayerNodeBase -> LinkLayerNodeBase with the later being the first one using actually implemented submodules.
The network adapter used is configured in the omnet.ini with *.host*.wlan[0].typename = "IdealWirelessNic". This module relies on Radio.
With all that found out you just need to look for API calls from Radio.cc made to RadioMedium.cc and you found the actual code responsible for sending data.
Understanding that chain of inheritance you can even hook in with your custom module at a level you find fitting. For example just implementing your own LinklayerNodeBase module.
If you are going for wireless communication and mobility, INET will still be the best framework to use.
Check out the INET Wireless Tutorial. It basically covers all the steps that you need to build a small scenario with moving nodes that communicate wirelessly.
