Abstract

The mergence of VoIP and WLAN has created a new wireless platform for voice service delivery- VoWLAN. Focusing on the hot spot of WLAN research, we figure out the capacity bottleneck of VoWLAN and the QoS problem of the VoIP service existing in current solutions such as M-M (Multicast Multiplexing) scheme [8]. A novel unicast multiplexing (U-M, Unicast Multiplexing) scheme to improve the voice capacity and guarantee the QoS of VoIP service in WLAN is proposed. Both theoretical and simulation results show that the U-M scheme doubles the number of VoIP users in VoWLAN as compared with traditional scheme and reduces the packet lost rate by nearly 10% as compared with M-M scheme. Meanwhile, U-M is also a power-saving scheme in the voice-dominant application typical of VoWLAN.
