WiFi network without routers

Question

Imagine we have N devices (say, mobile phones) with WiFi somewhere in a big desert (no area WiFi, no routers, no GSM signal, etc). Is it techincally possible to create dynamical network of such devices, so that they automatically discower new nodes and everyone can send messages to everyone (let us take simplest case - no broadcasting of messages, contacting devices should be in direct WiFi visibility to each other)?

Is it any java framework (SE or ME) exists ?

Answer 1

Mesh networks operate this way, but very few mainstream devices support the 802.11s standard.
