“…Kaschel and Toledo [101] introduced the cooperative and noncooperative sensing technologies in CR-based sensor networks and make a classification of the relevant spectrum management methods in detail. Luo et al [102] proposed a CR-based underwater acoustic network named UCAN, and simulations show that the performance of UASNs is improved greatly through the cooperation of PHY and MAC layers.…”

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.

“…To improve the data transmission efficiency, they adopt packet bursting, in which sender-receiver pairs can exchange multiple rounds of bidirectional packet transmissions. In [10], Y. Luo et al propose a receiver-initiated spectrum management (RISM) system for underwater cognitive acoustic networks (UCANs) and provide a method to jointly assign channel and power to maximize the spectrum utilization, which is evaluated by Aqua-Sim [11], an NS-2 based underwater network simulator, and shows a good performance compared with MMAC-CR [12]. In [13], Y. Dong et al propose a traffic estimation-based receiver-initiated MAC (TERI-MAC) for UWSNs in order to improve the handshaking efficiency.…”

In underwater acoustic wireless sensor networks (UAWSNs), designing media access control (MAC) protocols is highly challenging because of their significant influence on network performance. It is a great challenge to design suitable MAC protocols for UAWSNs because of the specific characteristics of underwater acoustic channels, such as low communication rates, large propagation delays, and limited available bandwidth. Orthogonal frequency division multiple access (OFDMA) is a special case of OFDM-based multicarrier modulation in which multiple user symbols are transmitted simultaneously using different subcarriers with overlapping orthogonal frequency bands. In this paper, we propose an OFDMA-based subcarrier pregrouping MAC protocol for UAWSNs, termed OSPG-MAC. To make it easier to allocate subcarriers and avoid conflict, we group all the subcarriers into fixed subchannels in advance and allocate them in terms of these subchannels. To maximize the total throughput on each subchannel, a bit and power allocation algorithm for the protocol is proposed, termed the OSPG-MAC algorithm. Simulation results show that the performance of OSPG-MAC is better than that of classic underwater MAC protocols, including SFAMA and T-Lohi.

“…The important feature of this protocol is that each node could adjust and extend the bandwidth of its control channel by flexibly selecting proper data channels. A receiver-initiated spectrum management (RISM) [20] system is another protocol proposed for UCANs. It allows acoustic users to efficiently and courteously utilize the spectrum with both natural acoustic systems and artificial acoustic systems.…”

Abstract:There are two different types of primary users (natural acoustic and artificial acoustic), and there is a long propagation delay for acoustic links in underwater cognitive acoustic networks (UCANs). Thus, the selection of a stable route is one of the key design factors for improving overall network stability, thereby reducing end-to-end delay. Software-defined networking (SDN) is a novel approach that improves network intelligence. To this end, we propose a novel SDN-based routing protocol for UCANs in order to find a stable route between source and destination. A main controller is placed in a surface buoy that is responsible for the global view of the network, whereas local controllers are placed in different autonomous underwater vehicles (AUVs) that are responsible for a localized view of the network. The AUVs have fixed trajectories, and sensor nodes within transmission range of the AUVs serve as gateways to relay the gathered information to the controllers. This is an SDN-based underwater communications scheme whereby two nodes can only communicate when they have a consensus about a common idle channel. To evaluate our proposed scheme, we perform extensive simulations and improve network performance in terms of end-to-end delay, delivery ratio, and overhead.
