Has anyone heard of an idea to use individual WiFi routers to communicate in a mesh net? (Or, at least differently than it may have been done before.) If you look at a map of WiFi routers (www.wigle.net) in any given area, you will see that the vast majority of routers are physically close to many other routers, certainly close enough to communicate with each other, and ultimately over a long distance. A crowd-sourced communication system, one that wouldn't necessarily go through the Internet backbone. Conceptually related to the Bittorrent system.

From that URL:
"Wi-Fi Direct, initially called Wi-Fi P2P, is a Wi-Fi standard enabling devices to easily connect with each other without requiring a wireless access point.[1] It is usable for everything from internet browsing to file transfer,[2][3] and to communicate with more than one device simultaneously at typical Wi-Fi speeds.[4] One advantage of Wi-Fi Direct is the ability to connect devices even if they are from different manufacturers. Only one of the Wi-Fi devices needs to be compliant with Wi-Fi Direct to establish a peer-to-peer connection that transfers data directly between them with greatly reduced setup.[citation needed] Wi-Fi Direct negotiates the link with a Wi-Fi Protected Setup system that assigns each device a limited wireless access point. The "pairing" of Wi-Fi Direct devices can be set up to require the proximity of a near field communication, a Bluetooth signal, or a button press on one or all the devices. Wi-Fi Direct may not only replace the need for routers, but may also replace the need of Bluetooth for applications that do not rely on low energy.[5]"
iirc set your WiFi router to bridge mode and tell it the ssid of the mesh network and your done. On September 15, 2015 12:21:10 PM CDT, jim bell <jdb10987@yahoo.com> wrote:

Most of the projects out there are using OLSR (http://www.olsr.org/mediawiki/index.php/Main_Page). A few are using the Babel protocol (https://github.com/jech/babeld). n.b., there is a difference between using a mesh networking protocol to distribute routes, and using IP forwarding to actually push the packets around. The two together are required.

Most wireless mapping software out these doesn't see interfaces in ad-hoc mode, only infrastructure mode. Thus, Wigle may not be the best way of mapping mesh networks in the greater context of wireless access points.

Wi-Fi direct is useful for short range comms. We've had a lot of trouble making it work over longer ranges. Wireless radios designed for use in infrastructure mode (including emitted power and duty cycle) are more reliable in the field.

Another standard. Yay. Time to find the docs and start reading...

It's an okay networking technology. It's a few generations behind what we're actually fielding these days but they're using OLSR for maintaining the routing table, so that's something. It's also hams only, so I'd advise caution if you don't have your ticket but want to experiment with it, new nodes that aren't recognized will draw a lot of attention.

I don't think that's a problem, since consumer grade routers don't have enough power to require a licensed operator. High gain antennas may be a gray area here, but since these would be pointed at participating reconfigured routers I don't think that would raise any eyebrows.

Yup, needs an ethernet connection for user access. Forwarding a mesh network router to a conventionally configured WiFi router is not a problem I have looked at yet, but I believe it should be easy.
