  This is a tricky question.  One approach would be to use a sleep timer in ROS:

  Another approach would be to put the camera thread to sleep for a certain amount of milliseconds with an instruction like the one below.

  this_thread::sleep_for(std::chrono::milliseconds(x))

  Where 'x' should be substituted for the value in milliseconds that you want the camera to sleep for.

  It can be used in a 'while loop' that determines when the camera thread is allowed to sleep.  Example:

  while (!frameArrived)
  {
      std::this_thread::sleep_for(std::chrono::milliseconds(100));
      std::cout << "Waiting for depth frame" << std::endl;
  }
