I'd still love ad-hoc better. HotSpot allows you to share 4G through WiFi, but it doesn't scale. The hotspot because AP, and that's the center of the network. On contrast, ad-hoc can scale to thousands of nodes across miles by using multiple hops. Also, ad-hoc is a more distributed model.
I never understood why ad-hoc mode was disabled by driver. AP mode (hotspot) is still available; users can still share their 4G connection without being approved by their carrier.
- lambda 13y agoAd-hoc networking on wifi generally only supports point-to-point links, not routing, unless you use another routing protocol on top of it like BATMAN Advanced. I'm not sure why connecting to an ad-hoc network is disabled in Android, but it's certainly never been anything that's caused me problems.
- songgao 13y agoRight. But I supposed by hotspot/ad-hoc, we were talking about the link layer possibilities only. hotspot is also about MAC layer only as well. IP runs on top of that. However, the difference is that, in AP/client mode, all nodes need to associate with and be able to talk to an AP; while in ad-hoc mode, every node is equivalent and they can be as distributed as they want. For ad-hoc routing, there're olsrd, batman, etc. They are really cool :-) We used to use Android devices to test different scenarios of ad-hoc applications. But none of current mainstream devices support ad-hoc mode any more. On contrast, iOS devices can still join (although not create) an Ad-Hoc network, which is ... ironic.
