Agenda

The agenda will be set after the workshop submission deadline, 1st of May. We will try to keep a maximum of 4 hours of talks per day, including breaks.

Talks

Time	Title	Abstract	Type	Speaker	Slides & Documentation
One hour	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.	Talk	Saverio Proto	Projector required
One hour	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.	Talk	Simon Wunderlich	Projector required
45 min	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.	Talk	Musti	Projector required
45 mins	WiBed, a testbed platform for WiFi experiments	Wibed is a platform for facilitating the quick and cost-efficient acquisition, deployment, and manage-ment 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.	Talk	Pau	Projector required
One hour	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
One hour	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)
One hour	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)
One hour	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
One hour	The Freifunk API	The Freifunk API is an approach of decentralized information gathering inspired by spaceapi.net. We'll introduce the API, show recent developments and give an outlook on future features	Talk	Monic & Andi (Saturday or Sunday only)	Projector required
One hour	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	Projector required
45 min	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	Projector required
45 min	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

Meetings

Time	Title	Abstract	Type	Speaker	Slides & Documentation
2 Hours	DIY ISP Meeting	Meeting of diy-isp from all over the world. We would like to continue our discussion that started at the 30C3 and FOSDEM and see how we can grow as community and share our knowledge about all the topics involved in changing the internet landscape.	Meeting	Philipp Borgers	Diyisp.org Project wiki, Pad with notes from the FOSDEM meeting, Pad with notes from the 30c3 meeting Projector required
2 Hours	BATMAN developers community meeting	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. Batman-adv Project wiki	Meeting	Mark Lindner
One hour	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
One hour	CONFINE project meeting	The CONFINE EU project aims at building research testbeds in community networks. The meeting is open to everybody.	Meeting	Clauz

Workshops

Time	Title	Abstract	Type	Speaker	Slides & Documentation
One hour	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	Projector required
Two hours	Amos sector antenna	Franz Streibl has proposed to give a talk / workshop about the new Amos sector antenna open-hardware design. He will offer a workshop of approximately one hour length where people can build this antenna from prefabricated elements for the 2.4 GHz WiFi band, if there is sufficient interest. We might break this up into a separate talk and workshop.	Workshop	Franz Streibl	Paper about the antenna: piamos_72_140323m.pdf

Social events

Thursday morning: Activity outside of the sublab and without laptops! More details to follow.

Saturday evening: Voku (Collective meal) at the sublab. This is normally every saturday evening at the sublab, and quite well attended. It could be a great way to finish the event and for other users of the sublab to find out what battlemesh is about.

more to be announced/proposed.
