Sending Hello messages between nods in ns3

[Ahmed M]

Hello everyone, 

I'm new to Ns3 environment and I plan to implement broadcasting protocol for VANET on Ns3. To begin with the implementation I need to send hello messages between nods with location information for each node. can you please refer me to any examples or pointers that I can read through to help me understand the steps to do so. BTW I read through Ns3 tutorial.  

thank you.

Dear Ahmed,

This issue has been discussed in the past several times. Search the mailing list archives for similar questions.

I would also recommend you to read one of the recent discussions on how to create your own routing protocol https://groups.google.com/forum/?hl=en&fromgroups#!starred/ns-3-users/kLRHv4D9CEU (please go through the complete thread, not just one post). You will see that the first point you should do is not go about and start writing code, there are more important parts to do first (i.e. design)

There are currently routing protocols in NS-3 that use HELLOs with different information. Study that implementation to understand how you can create, send, receive HELLOs. Then you should be able to modify them and add your own content (location information you like).

Regards,

K.

Hello Konstantinos, 

thank you for the replay I'm going to go through the link you provide me and read it carefully and I'll try to look at the already created protocols and understand it so it help me in the implementation process. I forgot to mention that the Broadcast is already designed and tested but not with Ns3. so I'll try to implement it on Ns3 in order to be used in the future for research purpose. 

sincerely.
