“…Every second hop of the packet in this work is examined to see if the node's status is void or not. A void-aware pressure routing (VAPR), which addresses the void problem in this class of greedy routings, is proposed in [19]. [20] makes a proposal for Clustered Vector-Based Forwarding (CVBF) routing protocol.…”

With the emerging technology in underwater wireless sensor networks (UWSN), many researchers are undergoing this field since it cannot maintain the batteries and recharge them manually. Network duration should be taken into account because they can easily be recharged by a non-conventional resource like solar energy. When coming to the data collection process, clustering is an effective method to construct vitality effective UWSNs. The clustering properties of UWSNs differ from those of terrestrial wireless sensor networks (TWSNs) due to the sparse deployment of nodes as well as the dynamic nature of the channel. This paper proposes improved efficient data aggregation in a Hexagonal grid with energy optimization (IEDA-HGEO) protocol for effective data transmission with an optimal clustering process. It is further compared with ERP2R n energy-efficient routing protocol and EGRC (Energy-efficiency Grid Routing based on 3D Cubes). The three techniques mentioned above are specifically examined for their applicability to underwater communication, and their performance is compared in terms of energy consumption, efficiency, throughput, packet delivery ratio, and delay. The proposed method achieved the following metrics: delay 41%, energy consumption 48%, efficiency 95%, throughput 95%, and PDR 92%.

“…Experiments show a higher bit error rate (BER) and outage probability than traditional methods. Goutham and Harigovindan [15] develop a full-duplex cooperative relay solution for a NOMA system (FD-CR-NOMA). The simulation results show that it significantly improves the ergodic rate, the probability of outage, and the energy efficiency of the UAN.…”

In orthogonal multiple access (OMA) communication systems, resources are allocated to numerous users based on time, frequency, or code domains. The low bandwidth of the underwater acoustic network limits the number of nodes that can be supported by the OMA system, due to limited resources. The innovative concept of nonorthogonal multiple access (NOMA) provides a solution that offers more nodes and increases spectral efficiency. As a promising technique, it optimizes power allocation through channel characteristics and adopts serial interference cancellation algorithms to decode the signal at the receiver. This paper introduces an underwater communication system based on the node pairing algorithm of maximum and minimum weight (MMW-NOMA). First, we build the system model in a UAN scenario. Second, we present the node pairing strategy. Third, we design a node replacement mechanism. Furthermore, we offer a power allocation algorithm. Finally, we compare the performance of MMW-NOMA with randomly paired NOMA (RP-NOMA) and orthogonal frequency division multiplexing (OFDM). Numerical results show that MMW-NOMA outperforms RP-NOMA and OFDM in throughput, mean square error, and energy efficiency. However, the complexity of MMW-NOMA is slightly higher than that of RP-NOMA but significantly lower than OFDM. These results show that MMW-NOMA achieves a reasonable trade-off between performance and complexity.

“…Performance analysis highlights throughput gains for FD relaying over HD relaying under perfect and imperfect SIC. The impact of imperfect SIC is also examined in Reference 28 for underwater acoustic sensor networks. Analytical and simulation results reveal that in such networks, two‐way FD NOMA relaying can improve both communication reliability and energy efficiency.…”

Non‐orthogonal multiple has the potential to improve the connectivity of wireless networks by simultaneously allowing users and devices to access the wireless medium. Meanwhile, full‐duplex communication can increase the spectral efficiency of the network as transmission and reception are concurrently performed. This article investigates full‐duplex two‐way relay communication relying on non‐orthogonal multiple access in the power‐domain. More specifically, users exchange superimposed signals and perform reception by utilizing echo‐cancellation and successive interference cancellation. For this setup, an extensive theoretical analysis is conducted, in terms of outage probability, error probability, ergodic rate, and throughput. Furthermore, by using the Lagrangian multiplier, optimal transmit power, and power allocation coefficients are determined and the relay's position is optimized to improve network performance. Our theoretical findings are verified through Monte‐Carlo simulations while significant performance gains in the optimized network case are observed.
