How to read the content of a socket

[xiexi...@gmail.com]

I want to construct a scenario where two node communicate via broadcast. For example, A sends a socket containing information about its location to B, and B receives it through another socket.

However, when i use the following code to read the content of B's socket, it is null. And I doubt if there is any bug of NS3 itself.

Can anyone answer it?

Hi

Please refer to the tutorial, for example the wifi-simple-adhoc.cc 

https://www.nsnam.org/docs/doxygen/wifi-simple-adhoc_8cc_source.html

The packet and generally everything would happen once you call the Run() which starts the actual simulation. So printing the packet before that would give you null
