Hi Everyone,
I'm planning to make Wi-Fi Web-server to send and receive data from Smart phones.
Configuration as follows ( Router/AP not to be used!);
Which is the most economical Wi-Fi module with built-in server code/library for Arduino?
WIZFI210, wiFly, Flyport etc..??
Any help would be much appreciated!
One thing you need to investigate is whether the device(s) support ad-hoc networking. Most shields do not, since that takes quite a bit of effort. Connecting a WiFi shield to an existing network is one thing. Creating a network is quite a bit more complicated.

Thanks PaulS
Can this be used?

I don't know. If you do get one, and it works, be sure to let us know. I'd get one, then, to play with.

Sure ... 
The Arduino Hydrogen WiFi shield supports Adhoc networking. It's available at diysandbox.com and they claim that their library is compatible to the Arduino Ethernet library.
I can't verify the latter statement as I have not yet had time to test that, however the samples that they host on github worked out "of the box" including the adhoc networking
