Abstract
We study end-to-end Quality of Service (QoS) support in a mobile ad-hoc network connected to a fixed IP network that uses Differentiated Ser-vices. We propose FA-SWAN (Fast Admission-Stateless Wireless Ad-Hoc Networks), a modified version of the SWAN scheme. SWAN uses local rate control for best-effort traffic and sender-based admission control for real-time traffic. Best-effort flows are delayed by a best-effort traffic shaper and real-time traffic that has not yet been admitted has to wait until the admission control process has finished. On the contrary, FA-SWAN allows real-time packets to be sent the before the admission control decision. Extensive simulation results show the performance of FA-SWAN with VBR VoIP (Voice over IP) connections, using CBR as background traffic. Moreover, we have evaluated FA-SWAN with an increasing CBR traffic load.
