While physical layer capture has been observed in real implementations of wireless devices accessing the channel like 802.11, log-utility fair allocation algorithms based on accurate channel models describing the phenomenon have not been developed. In this paper, using a general physical channel model, the authors develop an allocation algorithm for log-utility fairness. To maximize the aggregate utility, the algorithm determines channel access attempt probabilities of nodes using partial derivatives of the utility.
