ROS to publish/subscribe data wirelessly

Hi, guys.

I'm new to ROS, just finished learning the tutorials. I'm going to do a project, which requires to use ROS to publish/subscribe data from wireless sensors.

Let me briefly describe the architecture. There will be two sensors, communicating with each other with some wireless protocol. Two PCs running ROS will be connected to sensors, so data from sensors can be easily directed to ROS. After dealing with the data, one ROS is required to publish a topic through the sensor, and the other ROS needs to subscribe the topic wirelessly.

Please give me some hints.

Thank you guys in advance.
