Phoenix: A Hybrid Cooperative-Network Coding Protocol for Fast Failure Recovery in Ad Hoc Networks

Cooperative communication techniques have recently attracted much interest in the wireless research community. The possibility of achieving a low bit error rate without the need for special hardware (e.g., multiple antennas) has been the focus of a significant deal of research, especially at the physical layer. More recent studies have proposed medium access strategies that try to take advantage of cooperation. For instance, the authors propose a cooperative MAC scheme based on IEEE 802.11 where each node proactively selects a relay for cooperation and lets it transmit simultaneously when beneficial in mitigating interference from nearby terminals.
