We have thoroughly studied the paper of Perazzo et al., which presents a
routing attack named DIO suppression attack with its impact analysis.
However, the considered simulation grid of size 20mx20m does not
correspond to the results presented in their paper. We believe that the
incorrect simulation detail needs to be rectified further for the
scientific correctness of the results. In this comment, it is shown that
the suppression attack on such small sized network topology does not
have any major impact on routing performance, and specific reason is
discussed for such behavior.
