On-Demand Decode and Forward Cooperative MAC for VoIP in Wireless Mesh Networks

The employment of wireless mesh networking in real life scenarios has attracted substantial research interest in recent years and in this context VoIP has become a ubiquitous application. However, it has been demonstrated that VoIP transmissions over a multi-hop network may still remain inadequate in terms of their high packet-loss ratio and network-induced delays. To alleviate these limitations, the authors propose a novel distributed MAC-layer cooperation protocol, which is based on the decode-and-forward regime, whilst relying on the lowest possible control packet overhead.
