Abstract:
A method for improving access to a transmission medium in a network system, comprising:a first node detecting a transmission collision and determining if said transmission collision is with more than one other node; andsaid first node selecting a backoff window having a duration of r multiples of a predetermined backoff time, where r is a randomly distributed integer in the range: 0.ltoreq.r.ltoreq.2.sup.k, where k=min (n, 10), and, for each retransmission attempt, where n is a number greater than a retransmission attempt number, responsive to said first node detecting said transmission collision with more than one other node, and where n is a number equal to a retransmission attempt number responsive to said first node detecting that said transmission collision is with one other node.
