摘要： Disclosed are a method and a computer program product for achieving fairness in utilization of a channel in a network. The network includes plurality of stations such that at least one station of the plurality of stations includes at least one radio. The at least one radio may fail to access the channel even when the channel is available for performing transmission. The method includes determining a number of idle slots occurred at the channel during a disruption period when the at least one radio is unavailable for transmission. The number of idle slots occurred during the disruption period may be accumulated as a credit. Based on the accumulated credit, an initial value of a backoff counter of the at least one station may be reset. The reset initial value of the backoff counter enables the at least one radio to utilize the accumulated idle slots for next transmission.

摘要翻译： 公开了一种用于实现网络中的信道的利用的公平性的方法和计算机程序产品。 网络包括多个站，使得多个站中的至少一个站包括至少一个无线电。 即使当信道可用于执行传输时，至少一个无线电也可能无法访问信道。 该方法包括：当至少一个无线电不可用于传输时，确定在中断周期期间在信道上发生的空闲时隙的数量。 在中断期间发生的空闲时隙的数量可能被累积为信用。 基于所累积的积分，至少一个站的退避计数器的初始值可以被重置。 退避计数器的复位初始值使得至少一个无线电能够利用累积的空闲时隙进行下一次发送。
