Peer-to-peer VoIP (voice over IP) networks, exemplified by Skype, are becoming increasingly popular due to their significant cost advantage and richer call forwarding features than traditional public switched telephone networks.

In current wireless networks, channel access is controlled via either a TDMA- or a CSMA-based scheme. While usable in single-hop networks, these techniques are far from optimal and result in significant per-hop and per-packet delay an jitter. This makes multi-hop mesh networks unsuitable for several in-demand applications, including VoIP. We present a new medium access control (MAC) protocol for wireless...
