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

Action Items:

• Art, propaganda, manifestos!

  • mesh detected

• Explore batman vs olsr vs robin

• Mesh reading group?

  • Start here: http://www.wndw.net/

• Today I Learned? June 8th is available

• Radio show w/ Interviews? Jenny & Alcides

• 1 page description of mesh to distribute to everyday folks

• Let's make a mesh!

  • Test batman-adv for next week

  • Throughput and slow-down over multiple hops

  • Signal strength
