Space Full-Duplex Max-Max Relay Selection for Relays With Buffers
In cooperative relaying a number of mobile nodes assist a source in transmitting information to a destination. The two most common relaying protocols are Full-Duplex (FD) and Half-Duplex (HD). In FD relaying, the relays transmit and receive at the same time and in the same frequency band. However, with the current limitations of radio implementations, FD is difficult to implement in practice because of the strong self-interference. HD relaying is most often adopted due to its implementation simplicity. In HD relaying, the transmission is organized in two time slots. During the first time slot the relays receive the data from the source and during the second time slot the relays forward the processed data to the destination.
