A Conflict Modeling Method for Underwater Acoustic Networks Considering Channel Propagation Characteristics

Due to physical factors such as half-duplex communication mode, the propagation delay of underwater acoustic channels, and large Doppler, there are serious interference conflicts in underwater acoustic networks. The accurate modeling of interference conflicts is the key and foundation for the design of underwater acoustic network protocols and network performance evaluation. However, existing models do not consider the propagation characteristics of multipath and Doppler in underwater acoustic channels. This paper proposes a decoding conflict model that conforms to the propagation laws of underwater acoustic channels, achieving high-precision conflict modeling in underwater acoustic networks. The paper verifies the effectiveness of the model through simulation.
