A Software-Defined Opto-Acoustic Network Architecture for Internet of Underwater Things

Abstract

In this paper, we envision a hybrid opto-acoustic network design for the internet of underwater things (IoUT). Software-defined underwater networking (SDUN) is presented as an enabler of hybridizing benefits of optic and acoustic systems and adapting IoUT nodes to the challenging and dynamically changing underwater environment. We explain inextricably interwoven relations among functionalities of different layers and analyze their impacts on key network attributes. Network function virtualization (NFV) concept is then introduced to realize application specific cross-layer protocol suites through an NFV management and orchestration system. We finally discuss how SDUN and NFV can slice available network resources as per the diverging service demands of different underwater applications. Such a revolutionary architectural paradigm shift is not only a cure for chronicle underwater networking problems but also a way of smoothly integrating IoUT and IoT ecosystems.

Opportunistic Routing for Opto-Acoustic Internet of Underwater Things

“…The IoUT concept is surveyed in [13] where authors consider software-defined IoUT nodes that can employ acoustic, optic, and magnetic induction signals to overcome the peculiarities of the underwater environment. A softwaredefined opto-acoustic IoUT network architecture design is also proposed in [3] where authors explain inextricably interwoven relations among functionalities of different layers and introduce network function virtualization (NFV) to realize application specific cross-layer protocol suites through an NFV management and orchestration system.…”

“…Furthermore, the SectOR is an opto-acoustic (i.e., multimodal) OR scheme, where omnidirectional and long-range acoustic links provide several advantages: 1) acoustic systems can be used to create reliable command and control links. For example, the acoustic links can carry necessary pointing and alignment control data to re-establish broken optical links between disconnected nodes; 2) acoustic links can enable a 360˝neighbor discovery and help sending ACK/NACK messages to candidate set in case of optical link failures; and 3) hybridizing acoustic and optic links improves the localization accuracy [3], [31], which yields precise pointing between the optical transceivers and enhances the end-to-end link quality. The main contributions of this paper can be summarized as follows:…”

“…In order to protect oceans and reap their full profits at the same time, it is crucial to transport, store, organize and process the surging amount of data acquired from underwater sensors and fixed/mobile maritime terminals. To this aim, the internet of underwater things (IoUT) is a technological revolution towards integrating physical and digital worlds by interconnecting smart underwater objects [3]. Thus, IoUT could mark a new era for scientific, industrial, and military underwater Authors are with Computer, Electrical, and Mathematical Sciences and Engineering Division at King Abdullah University of Science and Technology (KAUST), Thuwal, 23955-6900, KSA (Corresponding Author: Abdulkadir Celik).…”

“…Even though these ranges are sufficient for singlehop UOWC applications such as cellular UOWNs and data aggregation via autonomous underwater vehicles [c.f. Fig 1 of [3]], realizing a large-scale UOWN is still a challenging task that requires effective multihop communications and routing methods, which is the main focus of this paper.…”
