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.
