Channel Modeling for Underwater Acoustic Network Simulation [PDF]
IEEE Access, 2020 This manuscript was submitted to IEEE Access on 12 Jun 2020. Abstract: Simulation forms an important part of the development and empirical evaluation of underwater acoustic network (UAN) protocols. The key feature of a credible network simulation model is a realistic channel model.

Hierarchical underwater acoustic sensor networks [PDF]
Proceedings of the Fifth ACM International Workshop on UnderWater Networks - WUWNet '10, 2010 We propose a hierarchical underwater acoustic sensor network architecture in which the sensors and the collector stations operate in distinct layers. The hierarchical architecture is motivated by the property of the acoustic underwater transmission medium that for each transmission distance there exists an operating frequency for which the narrowband ...

Simplified Scheduling for Underwater Acoustic Networks
Journal of Networks, 2013 The acoustic propagation speed under water poses significant challenges to the design of underwater sensor networks and their medium access control protocols. Similar to the air, scheduling transmissions under water has significant impact on throughput, energy consumption, and reliability.

A hybrid routing protocol for underwater acoustic networks [PDF]
2018 17th Annual Mediterranean Ad Hoc Networking Workshop (Med-Hoc-Net), 2018 —This paper presents a new packet-forwarding mechanism for underwater acoustic networks. The solution, termed MPR-Light, combines the modus operandi of the Multi-Point Relay (MPR) protocol and of the Enhanced Flooding (EFlood), both described in [1]. MPR-Light aims at providing the ro-bustness of a flooding solution in the presence of unreliable and ...

DCN-MAC: A Dynamic Channel Negotiation MAC Mechanism for Underwater Acoustic Sensor Networks
Sensors, 2020 In the design of media access control (MAC) mechanism in underwater acoustic sensor networks (UASNs), due to the propagation characteristic of low-speed underwater acoustic signals, it is necessary to solve the spatial−temporal uncertainty problem.
