Silent Positioning in Underwater Acoustic Sensor Networks [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2008
In this paper, we present a silent positioning scheme termed UPS for underwater acoustic sensor networks. UPS relies on the time difference of arrivals locally measured at a sensor to detect range differences from the sensor to four anchor nodes. These range differences are averaged over multiple beacon intervals before they are combined to estimate ...

Hierarchical underwater acoustic sensor networks [PDF]

open access: yesProceedings 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 ...

A Secure Remote Mutual Authentication Scheme Based on Chaotic Map for Underwater Acoustic Networks

open access: yesIEEE Access, 2020
Underwater acoustic networks (UANs) have emerged as a new wireless sensor network structure widely used in many applications. Sensor nodes are usually placed in a hostile and unattended underwater environment to gather information with limited resource ...

Krill: An exploration in underwater sensor networks [PDF]

open access: yes, 2005
While sensor networks have now become very popular on land, the underwater environment still poses some difficult problems. Communication is one of the difficult challenges under water. There are two options: optical and acoustic.

Pre-scheduling Pipelined Mode MAC Protocol for Underwater Acoustic Sensor Network [PDF]

open access: yesJisuanji gongcheng, 2017
Aiming at the delay problem of MACAW protocol in underwater acoustic sensor networks,on the basis of the traditional handshake protocol,this paper proposes a new Media Access Control(MAC) protocol for underwater acoustic sensor networks.The protocol uses

An efficient scalable scheduling mac protocol for underwater sensor networks [PDF]

open access: yes, 2018
Underwater Sensor Networks (UWSNs) utilise acoustic waves with comparatively lower loss and longer range than those of electromagnetic waves. However, energy remains a challenging issue in addition to long latency, high bit error rate, and limited ...

Remotely Powered Underwater Acoustic Sensor Networks [PDF]

open access: yesIEEE Sensors Journal, 2012
The remotely powered underwater acoustic sensor networks (RPUASN) paradigm is introduced, whereby sensor nodes harvest and store the power supplied by an external acoustic source, indefinitely extending their lifetime. Necessary source characteristics are determined.
