A new scheme to support voice call over wireless multi-channel MAC protocol
This paper presents a new scheme to support voice calls over a wireless multichannel MAC protocol (VMcMAC). We increase the voice capacity of wireless networks by reducing protocol overhead and interference between voice traffic and data traffic. Voice calls are allocated to specific reserved channels in a distributed TDMA fashion. Each voice node visits the voice channel with a fixed frequency and then transmits a voice frame without sending control messages. With this scheme, we exploit multichannel nature of 802.11 standards to significantly reduce the protocol overhead and avoid most of the interference between voice and data traffic. Our simulation results show a significant improvement in the voice capacity of wireless Ad-hoc networks.
