Real-Time Applications In 803.11 WLAN Using Feedback-Based Bandwidth Allocation
[chapter]
Distributed Cooperative Laboratories: Networking, Instrumentation, and Measurements
The Hybrid Coordination Function (HCF) has been recently proposed by the 802.11e working group in order to provide real-time services in Wireless Local Area Networks (WLANs). HCF is made of a contention-based channel access, known as Enhanced Distributed Coordination Access (EDCA), and of a HCF Controlled Channel Access (HCCA), which requires a centralized controller, called Hybrid Coordinator (HC). This paper proposes two feedback-based bandwidth allocation algorithms exploiting HCCA for
