Attendees

• Jenny, juul, substack, miguel, jordan, mark, rody

Announcements

• We've started an IRC channel on Freenode IRC: #510pen - come chat!
• Check the updated wiki at https://sudoroom.org/wiki/Mesh

Notes

• Marc researched Freifunk, which is both a firmware project, group organization and many small meshes throughout Germany: https://sudoroom.org/wiki/Mesh/Freifunk
  • Firmware is interesting – community profiles for a) chipset b) language and c) city
  • Does the work for you – source code is available.
  • As a node, you get a static public IP
• Commotion is based on the Freifunk
  • Available on more devices
  • Also works with OpenBTS
• OLSR - Layer 3, no kernal module so takes more CPU resources
  • Has an Android, Mac, and Windows version
  • OLSR has a watchdog which auto-reboots
  • Batman-adv is only available on Linux – you could port the protocol
• Hack to run DHCP to have dynamic IP assignments
• How to assign IP addresses: We could only run ipv6 – much larger address space – for random assignments of static IPs
• Hash the MAC address that's stored in a distributed manner
• Planned vs dynamic mesh networks
• Interoperability of protocols – batman as the backbone and OLSR/Babel on top
• Open Mesh
  • Pay for faster access
  • Small businesses, schools, RV parks etc
• Marc is going to buy a Freestation and some nanobridges ($85)
  • Omnis spread the signal too much
  • Ubiquiti sells antennas with 90 and 120 degree – this plus a router is $160-180
• Lasers! Temporary permits
• Cell phone networks – you can run up to 100 milliwatts without a license
• Critter (substack)
  • Re-sync once connected to the public network
  • Spot crowd-voting
• 5Ghz Backbone and 2.4Ghz connections between
• batman-adv:
  • multi-cast: avoids network saturation, allows for streaming that other nodes can choose to plug into
• Major issue is latency in hops
