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

“…Using TDMA or dividing the time into several slots, allows nodes only to transmit packets at the beginning of time slots, which causes excessive delay for time-sensitive applications. Due to the characteristics of underwater acoustic channel, using these approaches is not suitable for the requirements of time-sensitive applications as they result in high E2ED [ 60 ]. Table 3 highlights the characteristics and limitations of different MAC protocols.…”

In a channel shared by several nodes, the scheduling algorithm is a key factor to avoiding collisions in the random access-based approach. Commonly, scheduling algorithms can be used to enhance network performance to meet certain requirements. Therefore, in this paper we propose a Delay-Aware Media Access Control (DAMAC) protocol for monitoring time-sensitive applications over multi-hop in Underwater Acoustic Sensor Networks (UASNs), which relies on the random access-based approach where each node uses Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) to determine channel status, switches nodes on and off to conserve energy, and allows concurrent transmissions to improve the underwater communication in the UASNs. In addition, DAMAC does not require any handshaking packets prior to data transmission, which helps to improve network performance in several metrics. The proposed protocol considers the long propagation delay to allow concurrent transmissions, meaning nodes are scheduled to transmit their data packets concurrently to exploit the long propagation delay between underwater nodes. The simulation results show that DAMAC protocol outperforms Aloha, BroadcastMAC, RMAC, Tu-MAC, and OPMAC protocols under varying network loads in terms of energy efficiency, communication overhead, and fairness of the network by up to 65%, 45%, and 726%, respectively.

“…Fan et al [112] designed an SDN-based AUV system and implemented a test bed on WaterCom [113], in which the performance of the slotted FAMA [114] and UW-ALOHA [115] is tested and compared. Ghafoor and Koo [116] considered the natural and artificial acoustic systems as the two Primary Users (PUs) of UASNs and designed an SDN-based architecture in which buoys are treated as the Main Controllers (MCs) to maintain the global view of the network.…”

Underwater Acoustic Sensor Networks (UASNs) are an important technical means to explore the ocean realm. However, most UASNs rely on hardware infrastructures with poor flexibility and versatility. The systems typically deploy in a redundant manner, which not only leads to waste but also causes serious signal interference due to multiple noises in designated underwater regions. Software-Defined Networking (SDN) is a novel network paradigm, which provides an innovative approach to improve flexibility and reduce development risks greatly. Although SDN and UASNs are hot topics, there are currently few studies built on both. In this paper, we provide a comprehensive review on the advances in software-defined UASNs. First, we briefly present the background, and then we review the progress of the Software-Defined Radio (SDR), Cognitive Radio (CR), and SDN. Next, we introduce the current issues and potential research areas. Finally, we conclude the paper and present discussions. Based on this work, we hope to inspire more active studies and take a further step on software-defined UASNs with high performances.
