    @msvoelker you could put QUIC protocol in the transport layer and connect it to the MessageDispatchers above and below
    packets would go from the bottom of QUIC to the top of the UDP module and vice versa
    the app could simply go into the apps submodule as any other app
    SCTP also allows using UDP instead of directly relying on IP
    so it has the same problem

    SCTP also allows using UDP instead of directly relying on IP

    That's a good point. I will have a look at it. Thanks.

    Hello! How to record jitter? I am doing a video streaming simulation, but the simulation just record end-to-end delay.

    @statisticendToEndDelay"; unit=s; record=histogram,vector; interpolationmode=none);

    Can you help me to understand what is 'source=...' and 'record=...' please?

    Dear all,
    I am new to omnet++. I need to modify existing csma/ca, aodv, adhoc tcp and http protocols to enable me achieve the aim of my project.
    First, I need to simulate the current protocols without attack
    2nd, I will simulate all the current protocols with Jamming, MAC Flooding, Blackhole, SYN Flooding and DDoS attacks.
    3rd, i will simulate the modified protocols in the presence of all the named attacks.
    Can anyone give a step-by-step guide pls?
    Meanwhile, I have done the following:
    1, Omnet++ 5.5.1 already installed
    1. INET projects have been loaded.
    2. Also, I tried running the complete AODV first (AODV .ini file is in /examples folder while the .ned files are in /routing folder)
      So I could not successfully run. Morever, can I delete unwanted sections in .ini?
      All helps will be welcomed.

    Hello, it seems to be a low volume channel
    Hi, is someone using SUMO 1.1 or above for visualization? If yes, were you able to get the "bending while cornering" function working using guiShape parameter?
    Hello everybody...a few months ago I asked you about OMNet++ and your answers was great. Today I have got another question...I need to capture images from RTL-SDR to analize them...and I am not able to do that...someone who can assist me? (This is my second time here in Gitter...patience plz!)

    Hello guys,

    Need some help in OMNET++
    I am new to the networking field and started working with Omnet++ simulator(Version-5.6.1). In order to get a brief overview, I started working with the INET framework(Version 4.2). I have downloaded this framework from Github and imported into omnet++. Then, I started to build it and it's been successful. But when I run it, I got a few errors. The following is the error

    "<!> Error: Cannot load library '../../../src//libinet4.dll': The specified procedure could not be found"

    I tried few solutions in Windows and those are as follows:
    1) Linked the INET library to the OMNeT++ library folder-----> Failed
    2) In INET properties, changed the Target type to Executable------> Failed
    3) In INET properties, enabled the Force compiling object files for use in DLLs in compile section. Also, changed the target name to default:inet4 instead of the specified name------> Failed
    4) Tried it on Linux platform as well-----> Failed
    5) Installed INET from Omnet++ Help------> Failed
    6) Installed INET during Omnet startup-------> Failed
    7) Installed winpcap but no use ----> Failed

    Can anyone help to resolve this issue? It's been so long I have been working with this, yet I was not successful in it. Any help would be greatly appreciated.

    Best Regards


    I am working on the implementation of the following scenario using sumo OMNET++ & VEINS simulators.

    RSU will broadcast WSA (Wave Service Advertisement) Beacon once per second. to a specific vehicle.
    that specific vehicle would store these WSAs.                                           

    Issues regarding implementation:

    1. when i broadcast message it is received by all vehicles so how can i send message to a specific vehicle
      1. how can that message be stored by vehicle
        thanks in advance
    1) you can not. 802.11p messages are broadcasted and received by all vehicles within communication range. What you can do is filter messages according to different needs, meaning only "relevant" messages are handed over to the application layer (e.g., GeoNetworking).
    2) Messages can be stored in any data structure of your choice. For example, add an array where new messages are inserted. You may think of a time horizon where you start to drop/overwrite old messages.
    Hi All,
    I am looking to implement 10 vehicles and 1 RSU in VEINS Simulator. I am looking to deploy 10 cars in veins and how to connect each car. Is there any example in the veins tutorial? I want to deploy individual cars rather than changing the number of cars in the SUMO XML file.
    Has anyone tried to simulate Veins 80211p and veins_int 80211 vehicles in the same simulaion?
    Or does anyone know how to merge them together in veins_inet existing simulatiom.

    Some of my code use C++ 17 feature(std::optional). I'm working on a new project using OMNeT++, and want to use my current code. I already add CXX=clang++ CXXFLAGS=-std=c++17 to makefile, however it still not compile. I try make V=1, it seems that the CXXFLAGS not working. Any ideas?
    hi all
    I am working on a thesis project to blackhole attack detection and prevention in WSNs using omnet++. I am not able to find any algorithm or tool to generate the attack. please help me?
    Hi all! someone knows how to send data from instant veins (SUMO+Omnet++)simulation to sqlite3 (installed within debian)?
    Is it possible to set up VANET environment with Base Station/RSU initialized clustering using OMNET++ integrated with Veins and SUMO?
    And, perform ECC based mutual authentication using OMNET++?
    If yes, how it is being done???
    I have compiled INet, but how do I got Omnet++ to detect it? Is there some place/path I need to put it?

    I want to animate a node receiving messages from 5 different nodes in OMNET++. Right now the nodes send in a sequential manner. But, I want the nodes to send messages to the root node simultaneously. please help me

    @englishm @sanjaysrikumar please do you have any idea to solve my problem that mentioned above
    Hi everyone,
    i am new in OMNET++, i am trying to install OMNET 5.5.1 in my windows. everything finishes well but when i try to run program it gives me error "unknown log format character '<'" and when i press ok it disappear everything.
    Can anyone plese guide me
    @LHeilat_twitter I think you should be able to send the messages at the same time by scheduling the send() method at same time on all sender nodes. And for setting up animation, you can follow below INET tutorial,

    Hi Everyone,
    I am trying to implement a clock synchronisation mechanism in Wireless networks. But I am not able to find a Clock module which I can use in a wireless sensor node!! Can anyone please direct me to some examples of clock models in wireless nodes to get started with??

    Thanks in Advance

    Andras Varga
    A clock model is part of INET 4.3.0.
    gPTP for INET is being integrated currently.
    Thanks you Andras. I could import INET 4.3 and see clock models in there. Are there any simple examples other than gPTP which I can refer to?

    Good evening! I have a question. If in a wireless network with adhoc host I would like to implement a routing protocol where the forwarding nodes in the range of the sending nodes routes
    Route packets to the receiving node theough the two path with the least hop, what would you be modifying? The nexthopforwarding module?
