Abstract
Traffic flows of data packets from respective packet queues in wireless stations to a shared transmission medium of a wireless network are scheduled in accordance with Hybrid Controlled Channel Access (HCCA) and Enhanced Distributed Channel Access (EDCA). HCCA is applied by eliminating from consideration for HCCA access flows for which the sum of a desired minimum age of an oldest data packet in the respective packet queue and the time of creation of the oldest data packet is greater than the present time. For flows that are not eliminated from consideration, HCCA access is granted to the flow having a smallest sum of the desired maximum age of the oldest data packet and the time of creation of the oldest data packet. When all traffic flows are eliminated from consideration for HCCA access, EDCA is applied so that traffic flows compete for access to the medium.
