Medium time allocation and scheduling using ISO-zone structured superframe for QoS provisioning in wireless networks

摘要

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 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, a delay requirement, and local resource of an application stream; 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.

1. A method of transmission of information over a wireless network, said method comprising the steps of:
organizing a superframe into a plurality of allocation zones; grouping the allocation zones into iso-zones; generating an allocation map which correlates the iso-zones to the allocation zones; searching the iso-zones of the allocation map for transmission opportunities that accommodate a maximum periodic service interval and a medium time requirement of an application stream; and transmitting information from the application stream in the superframe upon finding said transmission opportunities in the searching step.
