I am working on packet analyzing software, so i just need a kick to start by reading the packets of wireless, but i dont have any idea regarding to it...
Any who handled such kinds of projects before please help me a bit....

You might want to look in to the JPcap library.

There is a rather nice tutorial here.

Being that this can output pcap files, you can even test it against Wireshark to make sure you are getting what you want.
