The new option positioning.filter.max-speed-cp allows to set an
alternative maximum speed when the mobile is found to be within
cp-reset-distance, instead of completely disabling the filter.
The new option positioning.filter.cp-reset-distance allows to disable
the filter when the unfiltered location of the mobile terminal is found
to be close enough to a capture point.
The new configuration option positioning.filter.max-speed allows to
specify the maximum speed at which the mobile terminals can travel; the
distance between two results for a given mobile will be limited to the
distance that it could have travelled, according to the two requests'
timestamps.
New autocalibration technique to generate points in line (use case:
underground tunnels). The handling of the
positioning.generate-reference-points has changed to be able to use
several autocalibration methods simultaneously.
The code for the EvAAL output was slightly updated in 2012 for the 2nd
contest. Although OwlPS doesn't handle sub-areas of interest, it was
indeed compatible with the 2012 evaluation system.
Like in the other modules, we get rid of the old use of "access point".
This has user-visible changes, especially in the configuration (the name
of a few options has been changed).
Change the positioning.generate-reference-points option to offer
multiple choices (false, mesh, list, both) and add the
positioning.generated-points-list to allow the user to specify a list of
reference points to generate.
Option positioning.generate-single-packet-reference-points becomes
positioning.generate-multi-packet-reference-points. The default is still
true, which means the default behaviour changed.
The option positioning.ss-similarity introduced in this commit allows to
chose the desired algorithm to compare two measurements. One can chose
between the historical mean euclidean distance algorithm and the new
algorithm using the number of values within the interval
[mean-std.dev.;mean+std.dev.].
The new option positioning.generate-single-packet-reference-points
allows either to generate one single packet in each generated reference
point, or try to match the real requests by generating packets
independently.
To generate the reference points, use only the APs at the same level as
the virtual mobile. This is very basic for now, please refer to the TODO
update for more details on what should be done.
To be consistent with the other modules, the positioning server must be
called OwlPS Positioner instead of Positioning, and the executable
owlps-positionerd (even if the daemon mode is not implemented yet).
That's a big commit for a tiny change.
