Acoustic Channel Modeling and Simulation for Underwater Acoustic Wireless Sensing Networks
Underwater acoustic channels are band-limited and reverberant, posing many obstacles to reliable, phase-coherent acoustic communications. In terrestrial wireless sensor networks, the nodes use radio frequency (RF) to build up the communication. In underwater environments, due to water absorption, radio wave does not work well. Compared to radio waves, sound has superior propagation characterist...
متن کاملModeling the Acoustic Channel for Simulation Studies
Underwater acoustic communications, especially from a single point-to-point link perspective, have been studied extensively in the past few decades. Underwater networking issues have begun to attract the interest of researchers as well, and represent a fertile research area which can be expected to grow in the future. Bringing the study of acoustic communications systems to the networking level...
متن کاملBehavioral Modeling and Simulation of Underwater Channel
Abstract— The Ocean is a dynamic and complex environment; it is a very complicated transmission channel that can change rapidly with the environmental conditions. Hence, to avoid failure of underwater monitoring missions, it’s crucial to predict the behavior of underwater acoustic channel. In this paper, several fundamental key aspects of underwater acoustic channel are investigated. A model ch...
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...
