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 | 9---+ | | | | | 14............18............16..............10----notebook ch13 ch13 : ch13 : :..............12 ch13 house pole car horse stand ... : 24BMit wireless link using ch01 or ch13 --- | 100MBit ethernet link
There 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 (udp.port == 4305) * 10.10.x02.Node/24 babelz (udp.port == 8475) * 10.10.x02.Node/24 olsr (udp.port == 698) * 10.10.x02.Node/24 bmx6 (udp.port == 6240)
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. Logfiles of the different shells can be downloaded here:
At some point, we have a very stable link between the Horse and the 9 laptop, with speed of about 350KO/sec to 400KO/sec.
