This ROS tutorial should do the trick: http://wiki.ros.org/tf/Tutorials/Writ...

If you know where it is, just publish a message at some rate with some timeout to keep active in the tree.

I have gone through this. But suppose, If I want my robot to go to the door. Then how can I do that ? Making the fixed frame of door ? And if I make a fixed frame of door then how do I know coordinates ?

Sure, that is one way you could do it. You know the coordinates by the detection and range you've mentioned before. If you don't have a 3D pose, you need to work one out and then publish in TF if you would like.
