A Request is received by *all* the APs, therefore we have to generate
one CalibrationRequest per ReferencePoint, and not one
CalibrationRequest per AP in each ReferencePoint.
The option positioning.accept-new-mobiles allows the program to add
on-line mobiles that are not declared in the mobiles' configuration
file. This was the default till now; now this option is unactivated by
default to avoid unexpected Wi-Fi devices retransmitting positioning
requests.
When a new calibration request is received, all the calibration requests
of the corresponding reference point are now cleared prior to add the
new request.
We should probably use a timeout to delete only the old calibration
requests and keep the recent ones.
The option positioning.accept-new-calibration-requests allows the
calibration requests sent during the positioning phase to be added to
the Stock. They are added to the calibration requests read by
InputDataReader during the start-up phase.
In InputUDPSocket, update the AP's coordinates when receiving a
calibration or autocalibration request that contains the coordinates.
This is done if the option positioning.update-ap-coordinates-online is
activated.
Add double Stock::ap_matrix_get_ss(transmitter, receiver).
This is the first step to handle self-calibration in owlps-positioning.
The idea is to simulates a square matrix of the listeners, with the
transmitters in one dimension and the receivers in the other dimension.
matrix[transmitter][receiver] is the signal strength received by
'receiver' from 'transmitter'.
The purpose of Stock::ap_matrix_get_ss() is precisely to access the
entry matrix[transmitter][receiver].
Note that the access is read-only, as the pseudo-matrix is (or will be)
filled by the standard mechanism of (auto)calibration requests and
measurements stored in Stock.
Add double ReferencePoint::average_measurements(string mac_transmitter),
that allows to get the average of all the Measurements sent by a given
transmitter.
Add, as protected functions, get_all_measurements(string
mac_transmitter) and get_requests(string mac_transmitter), that do the
same as get_all_measurements(void) and get_requests(void), but filtering
on the transmitter of the packets.
-lrt is now added as needed in each module Makefile, but not directly in
the library. Furthermore, the Makefiles add -lrt only if the platform is
Linux.
