“…As a result, the sensor node will become ineffective and stop serving after a short period of time, and the data in this field will be wasted. Therefore, the authors in [119] address this issue by introducing a sleep mode whenever a node is not sending data and is inactive, to reduce power consumption. Prior of going into sleep mode, the node was allowed to send more than one packet.…”

Underwater wireless sensor networks (UWSNs) have become highly efficient in performing different operations in oceanic environments. Compared to terrestrial wireless sensor networks (TWSNs), MAC and routing protocols in UWSNs are prone to low bandwidth, low throughput, high energy consumption, and high propagation delay. UWSNs are located remotely and do not need to operate with any human involvement. In UWSNs, the majority of sensor batteries have limited energy and very difficult to replace. The uneven use of energy resources is one of the main problems for UWSNs, which reduce the lifetime of the network. Therefore, an energy-efficient MAC and routing techniques are required to address the aforementioned challenges. Several important research projects have been tried to realize this objective by designing energy-efficient MAC and routing protocols to improve efficient data packet routing from Tx anchor node to sensor Rx node. In this article, we concentrate on discussing about different energy-efficient MAC and routing protocols which are presently accessible for UWSNs, categorize both MAC and routing protocols with a new taxonomy, as well as provide a comparative discussion. Finally, we conclude by presenting various current problems and research difficulties for future research.

“…Slotted_CS_ALOHA The authors in [82] outlined a major problem found in Underwater (UW) and proposed a Slotted Carrier Sense ALOHA protocol (Slotted_CS_ALOHA). This protocol attempted to solve an energy consumption issue since the sensor node is powered by batteries, which are not easily recharged.…”

“…Therefore, after a short period of time, the sensor node will transfer to a useless state and stop serving, and the data in this field will be wasted and not covered. So, the authors in [82] tried to solve this issue by putting the sensor node in sleep mode to reduce power consumption before this shift the node is allowed to generate more than one packet and go to sleep, this packet will go to the buffer and use the two conditions slot time and CS to reduce the possibility of collusion. In addition, there is a second buffer that will be responsible for handling the ALOHA cycle and passing only one packet to it and when the packet reaches its destination successfully, it will send another packet, etc.…”

the importance of these applications recently, there has been considerable interest in research analysis and improvement of UWSNs. The main reason for studying these networks is that they can enhance the ocean reconnoitering and meet the needs of multiple underwater applications [1][2][3][4]. UWSNs have protruded to be a master type of system for ocean exploration and vision where underwater sensor networks are used in the detection of underwater oil fields as well as identification of

“…Owing to the very limited bandwidth of acoustic channels and long propagation delays, the overhead of the signaling procedure causes severe deterioration in performance in terms of throughput and latency. Although there have been several works for freeing signaling procedure in MAC protocols, they are restricted to ALOHAand CSMA (Carrier Sense Multiple Access)-family protocols [15][16][17]. In [18], the ALOHA with carrier sensing (ALOHA-CS) is proposed using a new back-off window to adapt the protocol to variable propagation delay.…”

In this paper, we propose an underwater code division multiple access system where each sensor node independently evaluates whether a channel is available or not without control message exchanges with a central data-gathering node named a sink. A sensor node is able to estimate how large power is currently received at a sink in the distance based on the overheard power at the node from neighbors. If the estimated power is below a certain threshold level, the sensor node is allowed to transmit data in a p-persistent manner, where the probability p depends on the available capacity. Simulation results show the traffic estimation works well as demonstrated by a success probability of approximately 100%, and the data throughput improves in most of the offered traffic region because of the removal of the control signaling related to channel allocation.
