Allocation of contiguous blocks of airtime for data or airtime transmission can lead to large maximum service intervals for an application stream. This may result in a large delay bound where large blocks of contiguous MAS blocks other applications from meeting their low-latency requirements. A method and network that overcomes at least the shortcomings of known methods includes transmitting information over a wireless network. This includes the steps of: organizing the shared medium into periodical superframes; organizing the superframe into allocation zones; organizing the allocation zones into iso-zones; generating an allocation map; determining a periodic service interval and medium time based on a TSPEC including a latency requirement of an application stream, and local resource of the transmitting device; searching for transmission opportunity that accommodates the periodic service interval and the medium time required based on the allocation map; transmitting information in the superframe upon finding transmission opportunity in the searching step.
