Design 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...
متن کاملOn nearfield acoustic holography
Such functions u are called radiating solutions. Pressure measurements are taken by acoustical sensors located in a domain Ω0 inside or outside the cabin or on a surface Γ0 = ∂Ω0 . Our goal is to reconstruct u inside Ω, or the normal velocity v = ∂νu on Γ = ∂Ω, (ν is the unit exterior normal to ∂Ω). This is a mathematical model of the nearfield acoustic holography [W], [Wu]. H(m)(Ω) denotes the...
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 کاملFar-field acoustic holography onto cylindrical surfaces using pressure measured on semicircles
A simple formula was recently proposed by Williams @J. Acoust. Soc. Am. 99, 2022–2032 ~1996!# for imaging pressure and velocity on a vibrating circular cylindrical shell using the far-field pressure measured along a meridional semicircle. The method is examined and some new results are obtained. The procedure is generalized to handle cylindrical surfaces of noncircular but convex cross section....
