d. In the MAC protocol of 802.11, truncated binary exponential backoff

d. In the MAC protocol of 802.11, truncated binary exponential backoff (BEB) is used to resolve contention. The operation of BEB at an individual node can be modelled as a Markov chain, where each state represents the backoff state of a node. In backoff state i,i=0,1,2,3,,M, the contention window size Wi for a node is given by Wi={2iW2rW0i
