Implement the new MAC protocol which modifies the existing IEEE $802\mathrm{.}11$ protocol. The change required is in the sensing process: The current algorithm uses both backoff period and DIFS period to wait when a collision occurs. The modification required is to remove the backoff period and use only DIFS period for waiting after collision is occurred. To verify the working of modified protocol, simulate a wireless network consisting of $6$ mobile nodes $($nO $-$ n$5).$ Use the modified protocol. I want entire code from beginning pls I am cluless
