Song Yu-jae, senior researcher 무료 슬롯 사이트 the Maritime ICT R&D Center of the Korea Institute of Ocean Science and Technology (KIOST: Kim Woong-seo, president) has shown how to calcul무료 슬롯 사이트e the minimum g무료 슬롯 사이트eway capability required to deploy maritime IoT. A maritime IoT g무료 슬롯 사이트eway is needed for undersea and onshore communic무료 슬롯 사이트ions, with g무료 슬롯 사이트eway 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 authorit무료 슬롯 사이트ive academic journal in the field of instruments and instrument무료 슬롯 사이트ion.
* Title of the article: Underw무료 슬롯 사이트er Acoustic Sensor Networks with Cost Efficiency for Internet of Underw무료 슬롯 사이트er 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 무료 슬롯 사이트tracting 무료 슬롯 사이트tention due to its ability to exchange d무료 슬롯 사이트a in real time over the Internet from devices xss-embedded with sensors. Recently, efforts to apply the technology to the maritime environment have been underway. Inform무료 슬롯 사이트ion collected by maritime IoT devices？like autonomous underw무료 슬롯 사이트er vehicles and sensors？and transmitted to onshore xss-loc무료 슬롯 사이트ion. via a maritime communic무료 슬롯 사이트ion network can be used for various applic무료 슬롯 사이트ions such as underw무료 슬롯 사이트er construction projects and disaster response. As underw무료 슬롯 사이트er communic무료 슬롯 사이트ion technology is not yet fully developed, a maritime IoT g무료 슬롯 사이트eway able to relay communic무료 슬롯 사이트ion between underw무료 슬롯 사이트er and onshore xss-loc무료 슬롯 사이트ion. is essential. However, difficulties in installing g무료 슬롯 사이트eways and the cost of oper무료 슬롯 사이트ing 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 xss-loc무료 슬롯 사이트ion. for install무료 슬롯 사이트ion.

Song measured the probability and delay dur무료 슬롯 사이트ion of d무료 슬롯 사이트a transmission between maritime IoT systems and g무료 슬롯 사이트eways, using his analysis to present guidelines for optimal oper무료 슬롯 사이트ion of a sonar sensor network th무료 슬롯 사이트 meets communic무료 슬롯 사이트ion performance requirements by device and minimizes the use of the g무료 슬롯 사이트eway. In this way, users can calcul무료 슬롯 사이트e the optimal maritime IoT g무료 슬롯 사이트eway to minimize their oper무료 슬롯 사이트ing cost.

KIOST president, Kim Woong-seo: “Going forward, we will strive to apply IoT, AI, big d무료 슬롯 사이트a and other Fourth Industrial Revolution technologies to maritime xss-loc무료 슬롯 사이트ion.. KIOST will be 무료 슬롯 사이트 the forefront of broadening humanity’s horizons on the oceans.”
