To design a reliable and energy efficient medium access control (MAC) protocol for underwater wireless sensor networks (UWSNs) is an active research area due to its variety of applications. There are many issues associated with underwater acoustic channels including long and variable propagation delay, attenuation, and limited bandwidth which pose significant challenges in the design of MAC protocol. The available sender‐initiated asynchronous preamble‐based MAC protocols for UWSNs are not reliable and energy‐efficient. This is due to the problems caused by transmission of preambles for longer duration and collision of preambles from hidden nodes in sender‐initiated preamble‐based MAC protocols. To resolve these issues, the paper proposed an asynchronous receiver‐initiated preamble‐based MAC protocol named Receiver Preambling with Channel Polling MAC (RPCP‐MAC) protocol for shallow underwater monitoring applications with high data rates. The protocol is proposed to resolve data packet collision and support reliability in an energy‐efficient way without using any transmission schedule. The proposed protocol is based on the following mechanisms. Firstly, receiver preambling mechanism is adopted to reduce idle listening. Secondly, channel polling mechanism is used to determine missing data frame during its sleeping period and to minimize the active time of node and reduces energy wastage. Finally, a back‐off mechanism is applied to resolve collision when preambles are received simultaneously. In addition, performance analysis through Markov chain together with its validation with simulation‐based studies is reported in the paper. Both the analytical and simulation results have demonstrated the reliability achievable with RPCP‐MAC while providing good energy efficiency.

RPCP-MAC：接收器通过信道轮询MAC协议进行预优化，用于水下无线传感器网络

设计水下无线传感器网络（UWSN）的可靠且节能的媒体访问控制（MAC）协议是一个活跃的研究领域，这是因为其应用广泛。与水下声信道相关的许多问题包括长且可变的传播延迟，衰减和有限的带宽，这对MAC协议的设计提出了重大挑战。用于UWSN的可用的由发送方启动的基于异步前同步码的MAC协议不可靠且不节能。这是由于在发送者发起的基于前导码的MAC协议中，由于前导码传输时间较长以及来自隐藏节点的前导码发生冲突而导致的问题。为了解决这些问题，这篇论文提出了一种异步接收器启动的基于前导码的MAC协议，称为接收器预信道侦听与信道轮询MAC（RPCP-MAC）协议，用于具有高数据速率的浅层水下监视应用。提出该协议以节能方式解决数据包冲突并支持可靠性，而无需使用任何传输时间表。所提出的协议基于以下机制。首先，采用接收器前置机制来减少空闲监听。其次，使用信道轮询机制来确定其休眠期间丢失的数据帧，并最大程度地减少节点的活动时间并减少能量浪费。最后，当同时接收到前同步码时，应用退避机制来解决冲突。此外，本文报告了通过马尔可夫链进行的绩效分析，以及通过基于仿真的研究进行的验证。分析和仿真结果均证明了RPCP-MAC可实现的可靠性，同时提供了良好的能源效率。
