Support of IP QoS over wireless LANs

This paper addresses the potential issues that emerge when using WLANs as access systems to an IP core and focuses on defining a consistent mechanism that supports IP QoS and resource reservation over an IEEE 802.11e WLAN. The proposed approach assumes that RSVP is used for negotiating IP QoS parameters and reserving end-to-end resources. For interworking between IP QoS and WLAN QoS we propose a mapping between RSVP and 802.11e QoS parameters. In addition, we present how RSVP signaling is integrated with 802.11e signaling for WLAN resource reservation. Finally, we introduce a new scheduling approach for the 802.11e HC that can provide enhanced features.
