Description Tommaso Pecorella 2014-12-19 11:01:03 UTC

See https://groups.google.com/forum/#!starred/ns-3-users/jyW2iI_dEhc

The standard is not totally clear, but the general consensus is that the Backoff Period is between 0 and (2^BE - 1) including the boundaries. In the code the upper boundary is excluded.
