Neighbor Nodes Aware MAC Scheduling Scheme in Underwater Acoustic Sensor Networks

ECS: Efficient Communication Scheduling for Underwater Sensor Networks

“…One-slot approaches require that the transmission must be accomplished in a single slot, so the length of a time slot is at least one frame time plus the longest propagation delay of all links in the transmission range [ 6 , 7 , 14 , 16 ]. Paper [ 17 ] proposes a TDMA scheduling scheme for mobile underwater sensor nodes using an adaptive token polling, and paper [ 18 ] suggests a method that decreases energy consumption and propagation delays caused by channel collision by solving some problems of UWAN-MAC, which occur when the number of nodes increases. ST-MAC is the first multi-slot TDMA protocol especially designed for UWSNs [ 8 ], which allows more than one slot to accomplish the transmission of one packet between two neighbors.…”

Hybrid Deep Learning-Based Adaptive Multiple Access Schemes Underwater Wireless Networks

“…Yun et al [14] proposed that the CDMA protocol for underwater sensor networks uses adaptive token polling to decrease energy consumption, excludes collision, and avoids propagation delay problems. CDMA protocols play a significant role in the underwater sensor network and are classified into two classifications.…”

A Delay Time Overlapping MAC Protocol for Underwater Wireless Sensor Networks

“…Yun et al [6] suggested an idea to solve the energy waste that occurs when the existing MAC protocol recognizes a neighbor node. In the research, beacon signals are sent to neighbor nodes, allowing each node to record the existence of surrounding nodes.…”
