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.

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).

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.

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.

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.

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.

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.

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.

Retroshare - Secure decentralized communication for everyone and gaul.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.

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...

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.

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).

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.

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.

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.

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.
