An underwater acoustic communication scheme exploiting biological sounds
Underwater acoustic (UWA) communications have attracted a lot of interest in recent years motivated by a wide range of applications including offshore oil field exploration and monitoring, oceanographic data collection, environmental monitoring, disaster prevention, and port security. Different signaling solutions have been developed to date including non-coherent communications, phase coherent...
متن کاملDolphin Sounds-Inspired Covert Underwater Acoustic Communication and Micro-Modem
A novel portable underwater acoustic modem is proposed in this paper for covert communication between divers or underwater unmanned vehicles (UUVs) and divers at a short distance. For the first time, real dolphin calls are used in the modem to realize biologically inspired Covert Underwater Acoustic Communication (CUAC). A variety of dolphin whistles and clicks stored in an SD card inside the m...
متن کاملAquaTools: An Underwater Acoustic Networking Simulation Toolkit
High cost of development and deployment coupled with the complexity of the underwater acoustic channel makes it important to develop simulation tools which can assist in investigating underwater sensor networks and mobile autonomous underwater vehicular communications. Some recent developments have led to simulators which provide the ability to simulate mobile and stationary underwater acoustic...
متن کاملSimulation of Underwater Networks with KAM08 Acoustic Channel Measurements
The performance of underwater acoustic networks (UWANs) suffers from multipath and fast channel fluctuation, which severely limit the capacity of acoustic channels. Due to both logistic and technical difficulties of deploying UWANs for realistic scenarios, research involving UWANs has always been limited to either theoretical analysis or simulation study. For simulation, however, there are few ...
متن کاملDesign and Simulation of an Underwater Acoustic Local Area Network
An underwater acoustic (UWA) local area network (LAN) is designed and tested using Opnet's Radio Modeler. The network consists of master and sensor nodes that will be deployed in sea with battery powered modems. We modeled the UWA channel using the Radio Transceiver Pipeline stages supplied with Opnet. Since the network nodes are stationary, we assumed that channel is slowly varying and stays c...
