Hello guys, I'm implementing handover in this scenario of coexistence between wizi and zigbee (link below), but the AP works in a scalar way and in this scenario the type of radio is dimensional. Can someone help me to adapt the scalar to the dimensional? is that possible? thank you if you can help me
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"
Simulation terminated with exit code: 1

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.
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:
CXX=clang++ CXXFLAGS=-std=c++17to makefile, however it still not compile. I try
make V=1, it seems that the CXXFLAGS not working. Any ideas?
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
Hi, I am using OMNET++ INET for Ad hoc networks.
I want to broadcast my message to all my neighbours in UDP. I have tried all the possible solutions in UDPBasicApp. It broadcasts a message to one node at a time which it chooses randomly if the destination is not fixed (sink) . UDPBasicBurstApp also does not send message to all connected nodes.
Kindly help me in this regard.

Hi Everyone, I am working on a TDMA based wireless network in Omnet++ using INET library and facing below problem.
I am using ‘WirelessHost' as my wireless nodes’ type and configured the internal clocks of these nodes to run at different speeds using ‘SettableClockModule’.
I have modified the ‘LMac’ MAC protocol to use the internal clocks of their respective nodes by adding clockModule parameter. All I am trying to do is, access the medium according to the internal clock of the node, instead of simulator clock!
The PROBLEM I am facing is as below,
Below are the steps I tried,
Copied the message before scheduling in scheduleClockEvent method to deal with the ownership. Then, the message could be scheduled, but the Radio module will ry to pick it up and throw Unknown self message error,
Unknown self message -- in module (inet::physicallayer::ApskRadio) wireless_network2.TestNodeB.wlan.radio
Modified the ‘ApskRadio' Module as well with parameter clockModule and updating scheduling functions. But the network behaved the same way!
Please let me know if anyone can help me to fix this.
Any suggestions or documents related to message ownership problems OR any example projects to which I can refer will also be very helpful.
Thanks & Regards,

I am building a network topology with 12 nodes (all AodvRouter): 1 x Source, 9 x intermediate nodes and two destinations: Sink1 and Sink2. Please see the image for details: Network Topology.
At the moment all nodes are stationary (no mobility implemented yet). I am using UdpBasicApp at Source and UdpSink at destinations and trying to send UDP datagrams from source in multicast fashion to Sink1 and Sink2 nodes.
I have configured the Source and Sink1, Sink2 app in the ini file as follows:
# Source app configuration *.Source.numApps = 1 *.Source.app.typename = "UdpBasicApp" *.Source.app.destAddresses = "18.104.22.168" *.Source.app.destPort = 1000 *.Source.app.messageLength = 1000Byte *.Source.app.sendInterval = 100us *.Source.app.startTime = intuniform(0ms,1ms) # Sink1 app configuration *.Sink1.numApps = 1 *.Sink1.app.typename = "UdpSink" *.Sink1.app.localPort = 1000 *.Sink1.app.joinLocalMulticastGroups = true # Sink2 app configuration *.Sink2.numApps = 1 *.Sink2.app.typename = "UdpSink" *.Sink2.app.localPort = 1000 *.Sink2.app.joinLocalMulticastGroups = true
But I am not sure whether configuring Source app with
*.Source.app.destAddresses = "22.214.171.124" and Sink with
*.Sink1.app.joinLocalMulticastGroups = true is the correct approach.
Could you please advise? Thank you very much in advance.
