Enable phones to communicate with one another by mesh networking. See http://www.laptop.org/ and http://www.linuxdevices.com/news/NS9852477088.html . This would enable several cooperating phones to self-configure themselves as a mobile LAN without having to go through the cellular network or the Internet backbone. Could provide critical service in emergencies.

This might be combined with a push-to-talk functionality that would enable talk among phones even if there is no cellular coverage at that point, or to extend the range of cellular coverage by relaying through one cooperating phone within range.

the problem with this kind of feature is that any device in the mesh could potentially be a sniffer. the feature would have to be more of a buddy connect type of thing with no hopping onto the cellular network, otherwise critical information could be stolen, and data plans that aren't unlimited could be quickly drained. encrypted peer to peer wireless LAN would be nice though for connecting to friends to share data, play games and etc.

The concept of mesh networking doesn't presuppose the network is open to all would-be nodes. Indeed, it incorporates strong encryption as the default. It is the system being used by the U.S. military in combat operations, which allows every soldier with a computer to communicate with every other, and show one another's position and situation, but it is certainly not open to unauthorized systems. Of course, if the nodes were owned by different parties, there would need to be a protocol for adding trusted nodes certified by existing trusted nodes.

If the wifi radio hardware can allow it, it would be helpful if the device could participate in a connection to a wifi AP separately and and at the same time as participating in a mesh network. The two connections would be viewed by linux as two separate interfaces, each with their own IP address, etc.

@dornhetzel, I agree. Data connection via WiFi hardware would be great, if it is possible that android handsets can act at both host and client. I don't believe it is possible to develop mesh networking via cellular radio due to FCC (or otherwise) licensing. This sort of WiFi (or bluetooth, even) based mesh network would be ideal in emergency response scenarios where commercial communications are non-functional. In urban areas, if the density of people with mesh-wifi enabled mobile devices were high enough it might be possible to maintain a civilian communication network.

How does this fit with the new Wi-Fi Direct announcement?
, Oct 17, 2009
I'm actually very interested in this topic. I have a couple interesting social mesh networking applications I want to write but I need a mobile device with a wifi card that people actually take with them. Android would be ideal if they supported 802.11s or the latest linux kernel which has support built in.

In what way would it go against fcc regulations? Trafficwise it would just be a large-scale Wi-Fi LAN wouldnt it?

Just this year there will be probably a Google Summer of Code project dealing with adding a simple GUI for OLSR mesh protocol which would enable meshing of Android phones in community wireless networks using OLSR: http://wiki.freifunk.net/Ideas#Android_OLSR_GUI But it will require a rooted phone. It would be great if it would be possible to use ad-hoc mode, configure IPs and change routes officially.

http://www.engadget.com/2010/07/24/adobe-air-peer-to-peer-video-call-concept-android-app-hands-on/ Adobe has shown this concept using AIR and without 802.11s Can we do it without AIR & 802.11s ?
, Aug 9, 2010
@narendra.sisodiya P2P != mesh. You'd still need underlying IP connectivity for that AIR app to work. OLSR, 802.11s, or some other L2 routing algorithm is still needed.
, Aug 9, 2010
@pacobell - OLSR has been ported to Android.
, Aug 9, 2010
@csboyd07 Has olsrd been pushed upstream to the android codebase yet? Froyo integration?
, Aug 10, 2010
We have been trying to reach Android team about OLSR integration, but without success. There is now a GSoC project trying to bring mesh to Android: http://wlan-lj.net/wiki/Podrobnosti/MeshApp
, Aug 10, 2010
Yeah, I'd seen that project sometime this week. It looks promising, but I have my doubts it'll work without root. Also, being a proactive protocol, it may not be suitable for mobile devices that are CPU and energy constrained. The RA-AODV protocol that 802.11s uses would probably be a better fit in this case. Unfortunately, I don't think the IEEE has even reached a reference draft standard yet, so Google may be hesitant to pull the trigger on that just yet.
, Aug 10, 2010
Yes. It requires root. And yes, it drains the battery in four-five hours. But this is also the problem of WiFi itself not really suitable for mobile phones. There is no much difference with power consumption of being connected to the WiFi AP and using the phone for browsing or being connected to the mesh. But yes, it would be great if you would be just able to leave mesh mode on and thus contribute to the mesh as you move around.

I would be very interesssted in wireless mesh networking as defined by 802.11s as i need a mesh-enabled mobile for my research work. We do research on wlan localization techniques here in our rsearch group and one of our approaches is a cooperative localization using wlan mesh networks.

I reiterate this for the G2. As we contemplate the likely upcoming global economic collapse, we need an alternative to the backbones for communications. We need a wireless internet of portable nodes. See http://constitution.org/wipnet/wipnet.htm

@22 I found a workaround: http://en.wikipedia.org/wiki/Amateur_radio
, Oct 5, 2010
Ham radio is of course the old alternative for emergency communications, but it is insufficient for reliable data communications among multiple parties spread over the continent. The military has found it to be far superior to walkie-talkies, enabling every soldier with a laptop to share combat intelligence with one another in real time, to find or avoid enemies, acquire targets while minimizing collateral damage, assess situations, find IEDs, and move wounded. Civilians need similar capabilities.

google already invests in a Mesh style AP company. http://meraki.com Having them add this ability to the phone would be AWESOME. Think about it, your in a location where WiFi or Cell Infrastructure is damaged or non existent or you and team need a private network to be on at some location. This would allow you to stay in data communication sharing media/chat/P2Talk. Combine it with GPS Google maps a team could each member have a phone on them and they could track each other down. Someone goes missing? Don't worry their current/last location/path was logged by his peers on the mesh network. Need support but can't describe where or what your seeing? record photos/video/P2Talk with gps tag, it goes out on the mesh and all your peers will see it, then their peers.

The recent events in Egypt and the re-introduction of the "Protecting Cyberspace as a National Asset Act" has added new urgency to this issue. Android should offer mesh networking ASAP along with OS agnostic applications that may act as anchor nodes for the mesh.
, Mar 22, 2011
Portable wifi LAN and eventually population-wide mesh networks are where the internet has to go to survive. Net neutrality regulation is unlikely to be enough to prevent abuse by big telcos, and many are already predicting the Splinternet. Adding this support will put phones at the forefront of the next wave of internet development.
