Abstract
Synchronous and asynchronous data traffic over multipoint ad-hoc telecommunication networks is scheduled in frames, and bandwidth in such networks is allocated based on packet type and traffic type by a scheduler that points to frame descriptors, or data structures, that define where data is located, what packet type to use for the transmission, etc. The scheduling of reception is implicit, viz., there is always a transmit/receive descriptor pair. The same scheduler can schedule traffic in interconnected networks in which there is a participant, even if the networks are unsynchronized to one another, and the scheduler can schedule connection-setup actions, such as page and inquiry. The scheduler can also schedule non-actions, or inactivity, such as “no operation” and “sleep”.
