Is that possible in wpa_supplicant-0.6.9 ? I am right about my question 
and the configuration is correct.

I have created a network in which iwconfig displays like -

          ESSID:"UJJAL"  Nickname:""
          Mode:Ad-Hoc  Frequency:2.437 GHz  Cell: 02:21:01:4D:70:31  
          Bit Rate:54 Mb/s   Tx-Power=9 dBm  
          Retry limit:9   RTS thr=2347 B   Fragment thr=2346 B  
          Encryption key:<too big>   Security mode:open
          Power Management:off
          Link Quality:0/100  Signal level:-98 dBm  Noise level:-98 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:110771
          Tx excessive retries:12  Invalid misc:260   Missed beacon:0

I want to join with this network. Is there any application, if 
wpa_supplicant will not work, which can join to this network?

Thanks,
Ujjal Roy
