ABSTRACT:
A shared wireless channel may serve real-time traffic and non-real-time traffic. Depending on channel conditions, the real-time traffic may experience variable levels of quality. The present invention contemplates systems and methods for guaranteeing bounded access time for real-time applications in a shared wireless network in the presence of non-real-time traffic. The systems and methods provide mechanisms to adapt to changing characteristics of wireless channels and to maximize throughput of non-real-time traffic while preserving the quality of real-time applications. The systems and methods may be extended generally to provide adaptive control over the delivery of multiple classes of traffic to protect the quality of critical applications over a shared transmission medium, including IEEE 802.11 networks, IEEE 802.16 networks, and DOCSIS networks.
