Connect or disconnect iPhone to the Internet programmatically

Question

Is it possible to connect or disconnect the iPhone to connect to the Internet (via Wi-Fi or 3G) programmatically, if I know the IP address of the iPhone.

I developed a small application that will give all the devices connected to my router. Suppose 3 devices are connected to my router, namely. Device A, B, and C.

At some point I want to disconnect device B, perhaps because it uses most of my internet traffic. So can this be done or not. If so ... what should be my approach?

I just need to get features on or off.

Thanks,
