In this paper, we introduce a mechanism to improve the performance of ARQ over underwater links. Our scheme aims at reproducing a Selective Repeat ARQ strategy: to do this, it sets up a form of time-division duplex link between the transmitter and its receiver, by leveraging on the propagation delay incurred by underwater sound. In fact, such delay typically allows to interlace the transmission of data and ACK packets in such a way that the two operations do not interfere or cause nodes to be… CONTINUE READING
