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.
This new type of request will only be used in owlps-positioning, to
distinct the calibration requests that are issued from a real
measurement and those that are generated by the self-calibration
process.
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.
