Create a network+dhcp ?

When we share internet connection through ad-hoc wireless network, each individual connecting to our network will be assigned with an unique IP Address and other required fields will be filled with proper data(Gateway and ..).
I used this feature to access my iPad through wifi, and had no intention of sharing an internet connection.
Now that I don't have an internet connection to share, my computer doesn't give any IP to my device, therefore my computer is unable to see my iPad on the network.
I also tried "Create network" feature of mac, but again, since IP addresses have been assigned by self, I'm not able to see my iPad on the network.

Now here's the funny part, I used WireShark to watch packets on my network, and seems like both my system and iPad are broadcasting their information on network, but none of them see the other one!

Is there any solution to my problem? I basically want to create an ad-hoc network and access my iPad through it!

 

If I had a router, everything was automatically solved my friend
I set up an ad-hoc network using my Macbook running Mac.

I did try setting ip address and subnet mask manually, but it didn't work.
When I used internet sharing, my system was assigning iP address, and everything was fine. But if you don't have internet access but enable internet sharing, DHCP service does not work anymore. There must be internet to share for that service to work (I don't know why).

I was looking for way to manually start a dhcp service on ad-hoc connections.
Or simply any other way to make my iPad accessible from my Macbook.
