Abstract EN
In underwater acoustic sensor networks (UASNs), the propagation delay of acoustic signals is much longer than Radio Frequency (RF).
There is spatial unfairness problem caused by space-time uncertainty.
Hence, the design of Medium Access Control (MAC) is a challenging issue.
In underwater, it not only considers transmission time but also takes location into account.
In this paper, we propose Response to the Earliest Transmitter of RTS MAC (RET-MAC) protocol to solve the problem.
RET-MAC adopts adaptive RTS Contention Phase (RTS CP) to determine the earliest transmitter of RTS.
And CTS Delay Phase (CTS DP) is added to postpone sending CTS in order to avoid collision.
In addition, we propose CTS back-off mechanism to adjust the length of CTS DP as needed.
Contention back-off mechanism is used to reduce network congestion and increase fairness further.
The simulation results show that our scheme can achieve higher fairness and throughput; at the same time it also guarantees lower energy consumption and delay.
