Abstract
Media Access Control (MAC) Scheduling for Quality of Service (QoS) uses the bandwidth and delay requirements of a connection to calculate the polling interval, which is the maximum time that the scheduler can be away from the connection. The methodology involves deadline-based scheduling and adapts deadlines based on the number of packets actually arriving to take advantage of any excess bandwidth that is available.
