Abstract
Expected channel occupancy time is a wireless link metric determined based on a transmission protocol to be used for transmitting data in a wireless network. The wireless link metric may be used for routing or other network management functions. For determining the wireless link metric, an overhead is determined for one or more of accessing and releasing a channel to transmit a burst, including at least one frame, in the wireless network using the transmission protocol. An expected burst transmission time is calculated based at least on the overhead. The expected channel occupancy time is determined from the expected burst transmission time and an estimation of a number of frames to be successfully delivered during the burst.
