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
