Android : How to create the wifi tethering without sharing the internet connection(Hotspot) in android?

I'm having android(OS_VERSION 4.0) device. I would like to share the files to another android device through the wifi networks. I know, This can be done through wifi p2p(WifiDirect) in android 4.0 above. But this is not possible in android 2.3.3 devices(Prior to Android 4.0). I found the Superbeam application does the file sharing through shared networks in android 2.3.3.This application create the wifi tethering without sharing the internet connection of the device. The created tethering is only used for sharing the files not for sharing the internet. How to achieve this concept. Can anyone help me?
