20:00 - 21:00	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.	talk	Manos, Igor	wibed.pdf

14:00 - 15:00	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.	talk	Juliusz	babel-20150804.pdf

17:00 - 18:00	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	talk	dango	slides

13:00 - 14:00	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.

14:00 - 15:00	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. https://hyperboria.net https://docs.meshwith.me/Whitepaper.html	talk	ansuz & Lars
15:00 - 16:00	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. https://github.com/ipfs/ipfs	talk	juan

14:00 - 14:30	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.	talk	Jonathan	cake-battlemesh-v8.pdf
14:30 - 15:00	Why the Insecurities?	The state of security of all edge devices, and in particular, the tiny internet of things devices, is terrible. This short talk, goes into the cross layer issues at all 11 layers of the ISO network statck.	talk	dave / jim	battlemesh-security.pdf
15:00 - 16:00	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?

17:30 - 18:00	Preliminary Experiments with MultiPath TCP VPNs	Multipath TCP "aims at allowing a Transmission Control Protocol (TCP) connection to use multiple paths to maximize resource usage and increase redundancy" [source: wikipedia]. This talk reports some preliminary experiences about using VPNs on top of Multipath TCP.	talk	clauz	mptcpvpns.pdf
18:00 - 19:00	LigoWave	Talk about LigoDLB devices	talk	Ligowave
19:00 - 20:00	nmap security scanner	Presenting Nmap and how it can be used to investigate the security of our mesh networks, starting from basic usage, continuing explaining how to extend NSE (Nmap Scripting Engine) and finally giving an overview of the work I have done on Nmap during GSoC 2015 as student.	talk	g10h4ck	cancelled
19:00 - 19:15	News from the IETF Homenet WG	Homenet is an IETF working group that defines the architecture of future home routers. Homenet has a full implementation, based on OpenWRT and Babel. In this short talk, I will describe why the Homenet standardisation process is stuck.	talk	Juliusz Chroboczek
19:15 - 19:30	A UDP-based multipath application: mpmosh	Multihomed networks with source-specific routing gives new opportunities for the design of multipath transport or application layer protocols. Such a transport protocol is Multipath TCP: a compatible multipath replacement for TCP. However, some applications takes benefit to use UDP instead of TCP, and would not be improved by MPTCP. Mosh is a lightweight interactive application built over UDP, which reacts well in most situations. However, in some multihomed situations, it has some flaws which could be solved by considering multiple paths. In this talk, I will speak about my multipath version of mosh, that we will call mpmosh. The source code is available at: https://github.com/boutier/mosh . And a (to-be-updated) paper at: http://arxiv.org/abs/1502.02402.	talk	Matthieu Boutier	2015-08-BM8-mosh.pdf
19:30 - 19:45	Efficient Scientific Research	In this talk I address the typical hurdles of researchers organizing the body of literature they read and keep. Efficient researchers find ways to automate these boring tasks. Consequently, I present a utility belt of handy tools and scripts to automate the typical tasks.	talk	Thomas	https://github.com/Eden-06/gsresearch/blob/master/presentation.pdf

15:00 - 15:20	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.	talk and discussion	Nemesis	battlemesh-netjson.pdf
15:20 - 16:00	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 inconstant. 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.	talk	Nemesis	battlemesh-netjson.pdf

Sunday 9th August 2015

Do-what-you-want day. There are no programmed talks or workshops on Sunday, we can continue working on projects or just hang out together.

Lightening talks

The lightening talks will be held as self organized sessions. Feel free to pick any time without a talk and present your project/…. A good time is probably in the evening after the talks. That's also why they stop at (latest) 20:00.
