For wireless interfaces the diagonals of the bandwidth and latency matrices are very important.
They determine the duration of the tranmission for THE SENDER. It allows to have a different tx duration per node and per interface.
Thus, at each wireless communication, an addionnal event is created for the sender that corresponds to a send to himself (diagonals of the matrices) used
to unlock him from the api.send() call. Consequently, the duration of the transmission (by the sender) can be
different from the time at which the receivers actually receive the data (non-diagonal entries of the matrices).
