3.30pm-4.30pm	Introductory talk	We will introduce ourselves and the different groups and projects involved, explain logistics of the event, the agenda, and the mesh deployment. We will also introduce topics about the Wireless Battle Mesh event generally to be worked during the week and to be debated during the closing session (for example, the location for WBM v8).	talk	Organisers and participants	-
5pm-6pm	Wireless optical networking with KORUZA	After a brief introduction to wireless optical / free-space optical networking history and an overview of the technology you will be prompted to discuss ideas and play around with a low-cost 3D printable wireless optical system KORUZA and get tutored into establishing 100m long 1Gbps links, so one the design files are released open-source and parts/units made available, you will be able to start deploying such links as well.	Workshop	Musti
6pm-6.45pm	Hunting a digital fox at 5GHz	5GHz networks are generally deployed to cover larger distances and thus cover a wide area. Even a single or a few “evil” Wi-Fi transmitters may significantly degrade the performance of other devices and hinder a portion of the free spectrum useless. The talk is based on real events and will teach you the basic approach to analysing the spectrum at a given location and choosing a frequency, pinpointing the source of a wireless node performing a De-Auth attach on your node or generally spamming the spectrum, likely as a result of an infection with malicious code.

11am-12	CONFINE project meeting	The CONFINE EU project aims at building research testbeds in community networks. The meeting is open to everybody.	Meeting	Clauz
2pm-3pm	Cjdns & Project Meshnet	Cjdns implements an encrypted IPv6 network using public key cryptography for address allocation and a distributed hash table for routing This provides near zero-configuration networking without many of the security and robustness issues that regular IPv4 and IPv6 networks have.	Talk	Lars	Video, Slides, Source Code, OpenWRT Feed
3pm-4pm	CommunityCoin, a cryptocurrency for community networks	Based on the BitCoin block chain, the community coin (CCN) is a crypto-currency made for network Communities. The coin reward is not based on the block finding but in the contribution and participation of the community individuals. There is nothing to present because there is nothing yet implemented. However it might be an interesting topic to discuss about to see what the community network members around the world think.	panel discussion	Pau	Projector required CommunityCoin_slides.pdf
4pm-5pm	Netengine	Netengine is a new project started at the end of 2013. It is an abstraction layer to extract information from network devices. This talk will cover the basic concepts and explain the work being done on it plus the work the GSOC student will have accomplished before the event.	Talk	Federico (ninux.org)	netengine slides netengine github repository Video of the Netengine talk
5pm-6pm	B.A.T.M.A.N. V: what's coming next	A metric tailored around packet loss is not the best choice when it comes to determining the optimal path through the network. This talk presents the approach taken by batman's next generation routing protocol (B.A.T.M.A.N. V) covering a range of topics from multi-interface routing to bandwidth based routing decisions.	Talk	Marek Lindner and Antonio Quartulli	slides
6pm-10pm	Barbeque and Mesh presentation at the trailer park	We'd like to have a nice outdoor BBQ at the trailer park and do some presentation of the mesh network and voip setup there.	Outdoor	BBQ
8pm-9pm	BATMAN developers community meeting (at the BBQ)	Batman-adv users (wireless communities, commercial projects or other) may present their way of using batman-adv in real world setups to the present developers and batman users. The goal is to foster exchange about where and how batman-adv is used today, what are the challenges / difficulties while doing so and what can be done to further improve batman-adv.

1.30pm-2.30pm	Troubleshooting MTU problems on IPv4 and IPv6 networks	Ninux Roma is a Native IPv6 network with legacy support to IPv4. Usually we expect 1500 bytes of MTU and a boring NOC life. Unfortunately life is different. All kind of tunneling (VLAN, GRE, TINC, MPLS) are deployed on the Internet, eating bytes out of the MTU. Some mesh routing protocols use tunneling techniques themself. IPv4 packet fragmentation introduces bad performances but a working IPv4 end to end connectivity even if some link have a smaller MTU than needed. In the IPv6 Internet a MTU problem can blackhole your traffic. In this talk we will see some well known tools (ping6, radvd), and we will understand how to use them to check the end to end MTU.

6pm-6.45pm	Trusted multi-topology routing with Bmx6	Challenges, idea, and implementation of a receiver-driven approach for supporting securely-entrusted multi-topology routing for truly open and decentralized mesh network. First measurements quanifying cpu/memory/traffic overhead indicate the feasibility for supporting hundreds of nodes with (typical openWrt) embedded devices which shall be compared with further experiments during the event...	Talk	Axel	Projector required
7pm-8pm	Nodeshot / CitySDK	A talk about the new version of nodeshot and the work that has been done on the CitySDK project regarding common APIs, smart participation / active citizenship.	Talk	Federico (ninux.org)	Live test instance slides Github repository Documentation
8pm-9pm	Retroshare - Secure decentralized communication for everyone and qaul.net	This is a double slot. The first talk will cover the Retroshare project and introduce a Google Summer of Code projects, a social network plugin for retroshare. Followed by a talk on qaul.net, a user friendly, multi language, multi platform application that allows every one to build a self configurable wifi mesh communication network. It combines Wifi-configuration, mesh routing, network services such as public and private text chat, voice chat, file sharing and user discovery in single application. qaul.net networks connect e.g. informal settlements in the suburbs of Paris and is building an independent mesh network in Istanbul, Turkey.

2pm-3pm	Network Coding for Mesh Networks	The talk is a follow up on Martin Hundeboll's talk at BattleMeshv6 about the potential of network coding in meshed networks. Based on some examples the importance of protocol design for network coding is highlightes. Furthermore the basics of network coding are repeated in a nutshell to give the audience the basic understanding.	Talk	Frank Fitzek	Video (Youtube)
3pm-4pm	Are Wireless Community Networks really decentralized networks?	The topology of three networks (Ninux, FF-Graz, and FF-Wien) have been analysed to try to understand: * Are they really decentralized topologies? * Are they robust to failures/attacks/interception? * For those that use OLSR, why don't use MPRs?	Talk	Leonardo Maccari (researcher at the university of Trento, part of the Ninux network).	leonardo_wireless_decentralized.pdf Here is the original paper on this, limited to Ninux, presented it at CNBUB last year and at the Ninux-day in Rome. There is now much more data and some deeper analysis. Projector required
5pm-6pm	Dynamic Frequency Selection in 5 GHz mesh networks	The 5 GHz band is an interesting alternative to the crowded 2.4 GHz ISM band to set up mesh networks. However, DFS (Dynamic Frequency Selection) support is required in many countries to avoid disturbing primary users (e.g. military or weather radar systems), and DFS support was not available in open source drivers until last year. In this talk I'll present what DFS is and how it can be handled, summarise the current status in open source drivers and userspace tools, and discuss limitations and requirements to get it running in mesh networks.

Lightening talks

Session 1 - Friday 6pm - 7pm

Title	Abstract	Speaker	Slides & Documentation
Rugged Battery Pack	Rugged Battery Pack is designed to be used with Serval Project Mesh Extender in extreme environments and in developing countries, where power supply networks are limited , nonexistent or very intermittent, however there are very important use-cases here in Europe too. It can be charged by almost anything, from phone wall charger or a car to hand crank generators, cars, hacked together generators, wind turbines... The lightning talk can be extended in a longer session with the topic Powering wireless equipment deployments, the field Musti has quite extensive experience.	Musti (wlan slovenija)	Video of the talk
Minstrel-Blues - joint rate and power control	I will present my work on Minstrel-Blues, a Linux kernel module capable of jointly controlling transmit power and rate in real WiFi networks. By using his algorithm, spatial reuse is increased, and therefore the overall network throughput, by dynamically adapting the power level per link in such a way, that throughout per link is maximized while interference and spectrum pollution is minimized.	Thomas Huehn (aka Bluse-Blue)	Projector required
battlemesh.org	Status of the battlemesh.org infrastructure	Clauz	Projector required

Session 2 - Saturday 2pm-3pm

Title	Abstract	Speaker	Slides & Documentation
Open Building Interconnection Reference Model	Networks in small office applications and in small buildings called SOHO are typical application areas of Ethernet based communication services. Here, a new infrastructure concept is proposed, which is simple, clear and understandable for SoHo-Installations. The future target: By applying this concept, an entire building can be connected to the internet. All internet service can be established as a basic service of a building, similar to water and electricity installations. Finaly i will give a small outlook on my current work on benchmark methods for SoHo-Networks.	Peter Kußmann	BattleMeshV7_lightening_talk_OBI_final.pdf
