WiBed, a testbed platform for WiFi experiments

Wibed is a platform for facilitating the quick and cost-efficient acquisition, deployment, and management of testbeds based on commodity IEEE802.11 routers and enabling experimentation with wireless technology including the modification of low-level system components such as physical and link layer mechanisms, and network and transport layer protocols. WiBed was used, with partial (:-P) success in WBMv7 as the experiment firmware.

babel does not care

Babel is a robust routing protocol that just doesn't care. While initially designed to be reasonably robust and efficient on both wireless mesh networks and classical wired networks, over the years Babel has been extended with delay-based routing for overlay networks, with radio-interference aware routing, and even with source-specific routing. Whatever you throw at it, Babel doesn't care, it just keeps pushing packets in the right direction.
The talk will be elementary, and require little networking background.

GNUnet in community mesh networks

While originally meant to be used a framework for anonymous file-sharing, GNUnet has a lot to offer for wireless community networks as well: a truly distributed solution for name resolution, VPN tunnels and NAT traversal, to name just a few low-hangig fruits

source specific routing in babel

multihoming is a difficult problem, and, unsurprisingly enough, there are many techniques for multihoming, none of which are applicable in all cases. The mesh networking community has standardised on using tunnels for multihoming (as with the "smart gateway" OLSR plugin). The home networking community has chosen a different solution, called "source-specific routing.".
The first complete implementation of source-specific routing was done by Matthieu Boutier and Juliusz Chroboczek, and was implemented within the Babel routing protocol. In this talk, I will explain what are the difficulties with multihoming, explain how source-specific routing solves many of those difficulties, and give an outline of Babel's support for source-specific routing.

peer to peer IPv6 networking in cjdns

Cjdns builds end-to-end encrypted, peer-to-peer IPv6 networks with useful properties -- the biggest so far being Hyperboria. We'll give a brief introduction to cjdns, its goals, and design decisions. We'll also show a few interesting use cases, and what the Hyperboria community is up to.

redistributing the web with IPFS

IPFS is a global, versioned, peer-to-peer filesystem. It combines good ideas from Git, BitTorrent, Kademlia, SFS, and the Web. It is like a single BitTorrent swarm, exchanging Git objects. IPFS provides an interface as simple as the HTTP web, but with permanence built in. I'll give a brief introduction to IPFS, then show its potential use in mesh networks, for example as a distributed content cache.

Cake

Comprehensive Queue Management Made Easy - fq_codel is now widely deployed, and achieving vast reductions in network latency with load, primarily in QoS systems. Cake leverages the algorithms developed in fq_codel, is faster, uses less memory, and has fewer hash collisions. Work on cake is feeding back into the make-wifi-fast effort, as we also attempt to improve wifi behaviors under a wide range of conditions.

Addressing Insecurity in internet of thing devices - a 5 year plan?

openWRT vs. FCC - forced firmware lockdown?

The new FCC rules are in effect in the United States from June 2nd 2015 [1] for WiFi devices such as Access Points. They require to have the firmware locked down so End-Users can't operate with non-compliant parameters (channels/frequencies, transmit power, DFS, ...). In response, WiFi access point vendors start to lock down firmwares to prevent custom firmwares (such as OpenWRT) to be installed, using code signing, etc. Since the same type of devices are often sold world wide, this change does not only affect routers in the US, but also Europe, and this will also effect wireless communities.
We would like to discuss:
* What are your experiences with recently certified WiFi Hardware
* How can we still keep OpenWRT on these devices
* What can we suggest to Hardware vendors so that they keep their firmware open for community projects while still compliant with the FCC?

NetJSON

NetJSON is a data interchange format based on JavaScript Object Notation (JSON) designed to describe the basic building blocks of layer2 and layer3 networking. It defines several types of JSON objects and the manner in which they are combined to represent a network: configuration of devices, monitoring data, network topology and routing information. In this talk I'll introduce the basic concepts, motivations and goals. There will be some time left for questions and discussion.

How different nodeDB projects can start joining forces on specific modules/packages

A few years ago we had a discussion about joining forces on a Common NodeDB project which didn't go well. After years of development we still don't have what we all hoped for, mainly because our efforts are disconnected and incostant. How we can remediate? NetJSON could be a step in the right direction, but I also want to talk about the work we have been doing in Nodeshot to extract key features in separate python packages and which benefits this has brought to us.
