Infrastructure-based Localization System using Underwater Wireless Sensor Network

Abstract

Abstract:In this paper, an infrastructure-based localization method using underwater wireless sensor network (UWSN) is addressed. A localization using the UWSN is necessary to widen the usage of underwater applications, however it is very difficult to establish the UWSN due to the restrictions of water. In this paper, to extend the usage of UWSN at the infrastructure, we propose a sophisticated UWSN localization method using the Received Signal Strength Indicator (RSSI) of the electromagnetic waves. During the electromagnetic waves propagating in underwater, there arises a lot of attenuation according to the distance, while the attenuation shows uniformity according to the distance. Using this characteristics, the localization system in underwater infrastructure is proposed and the experimental results show the effectiveness.

Development of three-dimensional underwater localization method using electromagnetic wave e-plane attenuation pattern

“…However, there are some research methods on underwater localization using "EM waves Reduced Strength Signal [4]". In these studies, combining Friis and Maxwell equations is used to make the propagation model and calibration method in one-dimensional and two-dimensional spaces.…”

“…However, properties of acoustic sensors can cause reflection and reverberation in structured environments. Hence, to resolve this issue, some researchers suggested methods of EM wave localization in linear [2,3] and two-dimensional status [4]. As an extension of the previous results, in this study, a new approach of three-dimensional underwater localization method is proposed using "Electromagnetic waves (EM waves)".…”

Development of Underwater Short-Range Sensor Using Electromagnetic Wave Attenuation

“…First, we demonstrated the consistency of the RSS at the same distance using a radio-frequency (RF) sensor [11], and we obtained an approximate sensor model [19]. Based on these results, we conducted several experiments in an infrastructure-based underwater sensor network system [20]. Finally, we obtained an underwater sensor model and many worthwhile feasibility research results [21].…”
