MAP-NPS: A Novel Media Access Protocol Based on Node Pair Sequencing for Underwater Acoustic Networks

In this paper, we propose and analyze an new MAC protocol based on node pair sequencing (MAP-NPS), which requires node pairs achieved successful handshakes to realize multiple transmissions orderly after one-off RTS-CTS competition. We analyze and assess the protocol’s performance via simulations. Compared to the MACA-U [1] protocol and the PCAP [2] protocol, we show that the new protocol have better performance,which can improve throughput, decrease the propagation delay and reduce hidden terminals and exposed terminals.
