On Sunday afternoon, we finally managed to execute a number of test scenarios in the 10-nodes setup. Nodes were places between a horse stable, along a street and the house hosting the WBMv3.3 event. The following diagram illustrate the setup and the existing links:
11............17............15
| ch01 | ch01 |

ch13
house pole car horse stand
... : wireless link using ch01 or ch13
___ : 100MBit ethernet linkThere was line of sight (LoS) between the locations: * house - pole * pole - car * car - horse stand
Transmit power of all nodes was fixed to 5dBm
Data rate of all nodes was fixed to 24MBit
The following network ranges were used: * 10.10.x00.Node/24 static link local * 10.10.x01.Node/24 batman * 10.10.x02.Node/24 babelz * 10.10.x02.Node/24 olsr * 10.10.x02.Node/24 bmx6
where x could be: * x=2 for primary IP assigned to lan interface of node * x=1 for non-primary IP assigned to wireless interface of node
Node 9 was a notebook participating in the mesh via ethernet and running all 4 routing protocols.
Test scenarios were initiated from node 10.
From 10 we send simultaneous ping recored-route probes to 9 and 11 to observe the selected routes chosen by different protocols.
In parallel, we also downloaded data from node 9 to node 10 to saturate the links.
The test were executed by opening several ssh-shells into node 10 from the notebook.
