Acoustic event localization on an Arduino-based wireless sensor network
2014 IEEE Latin-America Conference on Communications (LATINCOM), 2014Valuable information from acoustic signals has not been fully considered into real applications associated with assisting people. In fact, the assessment of acoustic signals as an input parameter for localization techniques has useful applications in detecting the presence of living beings trapped in emergency situations by processing any type of sound

Refracted Acoustic Communications in Wireless Underwater Sensor Networks with Mobility
Proceedings of the 4th International Conference on Sensor Networks, 2015Routing is a fundamental function of any wireless network. For battery-powered underwater sensors using acoustic waves, routing is even more challenging due to an ever changing and communication-opaque ocean. Herein, we propose a shallow-water routing scheme that adapts to a unique physical phenomena of the medium.

Design of optical-acoustic hybrid underwater wireless sensor network
Journal of Network and Computer Applications, 2017Abstract High-speed underwater wireless transmission technologies are urgently demanded to transmit three-dimensional high-resolution observation data timely in ocean exploration. Currently, underwater acoustic sensor networks have obtained high transmission distance, but with low date rate, high power consumption, high cost and damage to marine ...

Mobile phone based acoustic localization for wireless sensor networks
2015 IEEE 2nd World Forum on Internet of Things (WF-IoT), 2015In wireless sensor networks, localization techniques are required for finding physical location of the sensor nodes. Most of the existing 2D and 3D localization schemes are reference based. Finding physical locations of sensor nodes in an application field with only 2D or 3D physical topology map or logical topology map is arduous and tedious.

The Gaussian Processes for Acoustic Localisation and Tracking in Wireless Sensor Network
5th International Conference on Imaging for Crime Detection and Prevention (ICDP 2013), 2013In this paper, the problem of enhancing the robustness of acoustic source localisation and tracking based on Time Delay of Arrival (TDOA) in wireless sensors networks (WSN) is considered. Distributed acoustic localisation is used relying on the sensing and the communication specification of the motes.

Acoustic localization based on wireless sensor network
2014Wireless Sensor Networks (WSN) has recently become tremendous application and research area. Accordingly, localization issue of WSN is becoming a hot topic, which aims to recognize the position of concerned object. However, it is well known that WSN is quite complicated in a real environment due to the characteristic of ad-hoc network and also limited ...

Modeling of acoustic propagation channel in underwater wireless sensor networks
The 2014 2nd International Conference on Systems and Informatics (ICSAI 2014), 2014Acoustic communication in the underwater wireless sensor network has many challenges due to the limited bandwidth and propagation loss and has attracted many researchers in the past decade. The diversity of an underwater acoustic channel due to time-variant nature of underwater channel can cause the divergence in the signal strength and can add some ...
