Summary: In this article, a hybrid coding-aware routing protocol (HCAR) is proposed for underwater acoustic sensor networks (UASNs). HCAR introduces interflow network coding and combines reactive routing with opportunistic routing to effectively reduce the number of transmissions. Simulation results and sea tests demonstrate that HCAR can optimize the routing problem of UASNs with multiple source nodes and a single sink node.

Summary: Underwater acoustic cluster networks (UACNs) are commonly used, but the traditional LEACH protocol faces issues of communication latency and energy consumption. To address this, the low-latency low-energy adaptive clustering hierarchy (L(3)EACH) protocol is proposed, which reduces overhead and provides a more efficient and scalable solution.

Summary: This paper proposes a dynamic layered routing protocol (BPDLR) based on back propagation neural network (BP-NN) to address the energy limitation and transmission delay issues in underwater acoustic sensor networks (UASN). The UASN is vertically divided into three layers and routing designs in each layer are predicted by BP-NN training model. Simulation results show that BPDLR protocol effectively alleviates the energy hole problem of UASN and extends network lifetime.

Summary: This article presents a cooperative communication scheme for reliable transmission in Underwater Acoustic Sensor Networks (UASNs) to address the challenging factor of propagation delay. The proposed scheme includes adaptive control packet collision avoidance and relay selection schemes to improve network performance metrics. Compared to existing methods, the proposed scheme significantly enhances network throughput, packet success rate, reduces packet drop rate, and minimizes latency.

Summary: This paper proposes a novel stochastic model for opportunistic routing (OR) in multi-modal UWSNs, and designs two candidate set selection heuristics to reduce energy consumption and improve the network data delivery ratio in multi-modal UWSNs. The proposed heuristics outperform classical related work protocols and the CAPTAIN routing protocol in terms of energy consumption and data delivery ratio.

Summary: The design of MAC protocols in underwater sensor networks faces challenges like long underwater acoustic propagation delay, high mobility, low available bandwidth, and high error probability. Contention-based MAC protocols are more expensive in UWSNs due to unique acoustic channel characteristics. Effective management of re-transmissions and collisions at the MAC layer is crucial for reducing energy consumption and improving network throughput.

Summary: This paper proposes a cross-layer protocol called CLIC based on directional reception to reduce network congestion and packet collision, improving the performance of underwater acoustic wireless sensor networks. The CLIC scheme incorporates an integrated routing-MAC design that utilizes directional beams to create optimum data transmission links with low interference and congestion. Simulation results demonstrate its superiority over other protocols in terms of packet delivery rate and energy efficiency.
