ABSTRACT
The Resource Reservation and Admission Control (RRAC) in WLAN networks is essential for real-time applications, especially VoIP over WLAN. In that respect, the RRAC mechanism must support the BSS and ESS scopes as well as different reservation types (per-flow, per-station, etc.). Therefore, we introduce the Traffic Source-based Priority Scheme (TSPS); TSPS enables the priority mapping with IntServ and IEEE 802.1D QoS schemes. To manage the WLAN resources according to the admission control, the channel capacity is mapped according to different types of traffic (management, applications, etc). Consequently, certain RRAC mechanisms and algorithms for BSS and ESS scopes are developed to deal with different architectures and reservation types. Based on that, we implement a system prototype, called Lobaq; the experimental results present the major functionalities of the system behavior under different conditions.
