Song Yu-jae, senior researcher at the Maritime ICT R&D Center of the Korea Institute of Ocean Science and Technology (KIOST: Kim Woong-seo, president) has shown how to calculate the minimum gateway capability required to deploy maritime IoT. A maritime IoT gateway is needed for undersea and onshore communications, with gateway selection determining the economic feasibility of maritime IoT. Thanks to his research, a cost-effective maritime IoT system can now be built. Moreover, an article he authored* has been published on IEEE TIE**(mrnIF*** 100), the most authoritative academic journal in the field of instruments and instrumentation.
* Title of the article: Underwater Acoustic Sensor Networks with Cost Efficiency for Internet of Underwater Things
** IEEE TIE (Institute of Electrical and Electronics Engineers Transactions on Industrial Electronics) is an academic journal for IEEEs in industrial electronics
*** mrnIF (modified rank normalized impact factor) refers to an average standardized rank-normalized impact factor per article, which represents the impact of an article in a given sector.


With advent of the Fourth Industrial Revolution, the IoT, or the Internet of Things, is attracting attention due to its ability to exchange data in real time over the Internet from devices embedded with sensors. Recently, efforts to apply the technology to the maritime environment have been underway. Information collected by maritime IoT devices?like autonomous underwater vehicles  and sensors?and transmitted to onshore locations via a maritime communication network can be used for various applications such as underwater construction projects and disaster response. As underwater communication technology is not yet fully developed, a maritime IoT gateway able to relay communication between underwater and onshore locations is essential. However, difficulties in installing gateways and the cost of operating them remain serious challenges as they are installed in the form of buoys and it takes a lot of time and costs for device-mounted ships to move to specific maritime locations for installation.


Song measured the probability and delay duration of data transmission between maritime IoT systems and gateways, using his analysis to present guidelines for optimal operation of a sonar sensor network that meets communication performance requirements by device and minimizes the use of the gateway. In this way, users can calculate the optimal maritime IoT gateway to minimize their operating cost.


KIOST president, Kim Woong-seo: “Going forward, we will strive to apply IoT, AI, big data and other Fourth Industrial Revolution technologies to maritime locations. KIOST will be at the forefront of broadening humanity’s horizons on the oceans.”
