My Battle of the Mesh 2009 v2 report

Hello World !

this weekend for the first time I partecipated to a Battle of the Mesh, an event organized periodically to test routing protocol implementations for mesh networks.

First of all I have to thank a lot Benjamin Henrion for the great hospitality !! He hosted us the all weekend and we really felt like at home ! :)

There were about 15 people at Okno coming from all across Europe to experiment together for a weekend. Activities were organized with a wiki page, that now contains a lot of useful information.

I went with Claudio. We have been identified as the olsrd team, even if we are not real core developers but we just contributed to the project with a couple of plugins. However, we successfully worked on olsrd, and with the help of Szczepan Jany we found a bug in the current stable version that was fixed right away by the real olsrd developers that were following our progress online.

Another good thing about the event is that I got much more familiar with the OpenWRT toolchain insights, and with the UCI interface to push settings into the router.

What was really impressive was the big amout of hardware available! We had countless Foneras on our desk and also many other wireless devices !! Nicolas Thill developed a set of scripts to configure in batch multiple devices. The key idea was to compile a firmware with an embedded public ssh key, so that automated scripts could push UCI settings into the devices. To loop between the devices a list of MAC addresses is passed to the script that hacks the ARP cache to jump from one device to another… of course all this is documented on the wiki :)


The only thing that was bad to me was the terrible cold I got on Saturday, that made me feel like a zombie for the all day :( I have to say I enjoyed much more Friday and Sunday !! Hopefully Pieter healed me on Saturday night with some “Rum & Honey” Belgian medicine :)

More pictures of the event have been published here.

I hope to see many people present at the Battle of the Mesh very soon in Rome for the Ninux Day ! :)

    Packet loss on very weak path 11-5 (very weak routes available)
    Packet loss on weak path 11-13 (weak route)
    Packet loss on decent path 11-25 (fair paths available)

    can anyone tell me that how to define the very weak,weak ,and fair paths?
    the node map show at

    between node 11 and node 5 got many unavailable path so it is defined as very weak route?
    between node 11 and node 13 seem like can route directly so it is defined as weak route bcoz node 13 may be unavailable?
    node 25 is quite far from node 11,then why is defined as fair paths available???bcoz they are far away so there got many paths can reach from 11 to 25
    so what is mean fair paths available juz many paths can route but not mean got a very good route between them right?

    if the definition is defined based on other detail,please giv me the link of the detail,
    thanks so much
