How data from one node send to another ?
I want to build an IOT-OS where one node can communicate with another. Ros sends data from one topic to another or from one node to another.
I want the basic source code for understanding in depth exactly how ROS is doing such a thing. I am also open to suggesting which can help me solve my problem.
Even a simple link to rostopic and rosnode source code where transferring of data might be taking place would be fantastic.
