ROS topic structure?

What is the basic structure of any topic on ROS? My aim is to convert every topic to a binary data, that can be send on a network. And again publish each topic from its respective binary data.

I am getting help from rosbag and wifi_comm packages. I am not getting complete information of basic structure of topic.

Thanks

You should look at ROS' message serialization. It already does exactly what you want - convert it to binary and send it over a network.

You do not have to serialize the messages yourself when using wifi_com. You just create a new instance of the WifiComm class and tell it what topics to forward and it should just work. Try looking at the file examples/wifi_comm_example.cpp in the wifi_comm package. There doesn't seem to be much of a tutorial for it, sadly, but make sure to read it to find out about how to use olsrd also.
