Experimenting with WRTnode
We are experimenting with the WRTnode.
qMp is already available for this tiny and powerful device. You can find the ready-to-install binaries of the development version in our official repository: http://fw.qmp.cat/kalimotxo
It can be seen in the pictures that we connected several elements to the board pins:
- Ethernet cables (the device integrates a 5 ports switch)
- a USB camera
- a relay to remotely lock/unlock a door
The WRTnode performs very good, it has a huge amount of flash memory (16 MB) and a MIMO 802.11n 2.4 GHz radio which seems to work quite fine also in adhoc mode. It is actually a nice device for use in home automation, drone/robotics stuff, as a control device (to provide access to other devices via the serial port, for instance) and so on, while meshing in 2.4 GHz using qMp.

Wireless Battle of the Mesh v7
The "Wireless Battle of the Mesh" is an event that aims to bring together people from across the globe to test the performance of different routing protocols for ad-hoc networks, like Babel, B.A.T.M.A.N., BMX, OLSR, and 802.11s. Of course, new protocols (working on OpenWRT) are always welcome!
This year, version 7 of the event will take place from Monday 12th till Sunday 18th of May at the sublab (http://sublab.org/) in Leipzig, Germany.
The qMp team endorses and supports the Battle of the Mesh v7 because of the efforts made by its community to advance the field of wireless mesh networking and foster the development of grassroots community networks.
The qMp project will support the event by:
- coming to the event and convince others to do the same
- help to set up the testbed and analyze measurement results
- give talks about advancement of our system and it's usage in communities
Many other communities endorse and support the Wireless Battle of The Mesh v7, an up to date list of the endorsers of the Battlemesh v7 can be found at the main Battlemesh website: http://battlemesh.org.

IEEE paper about a qMp deployment in Barcelona
A new paper has been accepted and published in the IEEE MWSWIM 2013 conference.
It is an analysis about the qMp network deployed in Barcelona (Sants/UPC), taking measures for more than 5 months.

New qMp map tool
The qMp firmware has a new map agent based on the Altermesh map tools which can be found here1. The difference with the one included in qMp (b6m) is that this second one is distributed and altermap is centralized and needs a central server to work.
It is very simple, easy to use and it consumes a very few amount of resources in the node, so I have thought it would be nice to have it in parallel with b6m. For quick deployments where nodes are moving, using it does not have any sense but b6m yes.
To use it you need to have the last qMp version. Once it boots, every hour it will send some information about the node to the central server (which is currently managed by AlterMundi people). Execute "altermap-agent" to force the refresh of the information.
Then the node owner must go to this site2, select the qMp.cat network and click the button "Add node". In the field have to be introduced the exact hostname of the node (i.e GSalcolea46-fs), and then pick the map position and you are done!!
I hope you enjoy it!
