Abstract
The presented invention provides methods and apparatus to generate a efficient medium dedication schedule which give wireless medium the ability to serve real-time and non real-time application concurrently and still be able to maintain the QoS as requested by real-time application. Furthermore, it also presents methods for implementing buffer in an efficient matter in order to complement the advantage introduced by burst transmission and burst acknowledgement.
Claims18
A method for guaranteeing a quality of service (QoS) in delivering real-time data across a transmission medium, comprising:
- specifying a traffic requirement for a traffic stream in accordance with a generic first specification;
- transforming the specified traffic requirement in accordance with a generic second specification based on the specified traffic requirement, an overhead requirement for the traffic stream and a condition of the transmission medium;
- adjusting the generic second specification based on feedback obtained from monitoring the condition of the transmission medium;
- aggregating a plurality of specifications for a plurality of traffic streams into a single specification to reduce resources required to maintain and process the plurality of specifications and overhead incurred in medium dedication;
- generating a medium dedication schedule according to the single specification;
- and
- performing medium dedication in accordance with the medium dedication schedule to coordinate transmission of the plurality of traffic streams.

- generating a medium dedication schedule according to the single specification;
- performing medium dedication in accordance with the medium dedication schedule to coordinate transmission of the plurality of traffic streams;
- determining, in units of transmission, a number of units for an amount of traffic to be transmitted within a duration interval, as one of a single data packet transmission and a burst transmission of a series of data packets;
- determining the duration required to transmit a unit of transmission;
- and
- multiplying the determined number of units with the determined duration,
- wherein the generic second specification specifies:
- a highest bound and a lowest bound of medium occupancy duration;
- a highest bound and a lowest bound of dedication interval;
- and
- a computation interval.
