Special Issue Information

Dear Colleagues,

1. Land-based Data Communication Networks are continually making progress. Regarding Maritime Communications, however, remaining problems include slow communication speeds and limited communication capacity.

  1. For digital data exchanges, a special focus will be on Maritime Communication Networks that are continually updated in a timely fashion in order to reflect such developments as autonomous vessels.
  2. Applications will include digital data exchanges via satellite, via communication network facilities constructed at sea, and the utilization of such digital data exchange methods as VDES. Particularly for application to next-generation Intelligent Ships and automatically operated ships, they will be applied to Maritime Search and Rescue as well as to Global VTS (Vessel Traffic Service).
  3. Previously, maritime communications have mainly relied upon radio-telephone communications for ship operations. The exchange of digital data is indispensable for the development of next-generation ships such as self-operated ships and intelligent The purpose of this publication is, therefore, to collect and publish cutting-edge topics related to maritime wireless communication in a timely manner.

2. Journals related to electrical and electronic communication engineering (IEEE, etc.) and journals related to marine engineering (JMST) cover topics such as specific technological development. However, since such information is rarely provided having a viewpoint of maritime communication networks, we believe that they will be effectively complemented in a timely manner.

Traditional methods of marine navigation are undergoing a revolution brought about by the almost universal adoption of the Automatic Identification System (AIS). AIS exchanges a wealth of navigational information among vessels and between ships to shore through Very High Frequency (VHF). With AIS data integrated into the Electronic Chart Display and Information System (ECDIS), the identification and navigational information of surrounding vessels as well as aids to navigation can be reflected on the electronic charts in real time, despite some problems such as the low AIS carriage rate on small vessels where it is not mandatory and the high cost of ECDIS preventing such vessels from installing it. In this paper, we introduce BlueNavi, a lower cost but sustainable maritime information providing platform built with microservices architecture allowing flexible on-demand scalability and cross-platform adaptability. Applications served by BlueNavi can provide users with data either stored in a remote data center through the internet or received locally by devices connected to the station without the need for the internet. From our land test, we show that users with only an internet connection but without any AIS equipment can also obtain live AIS data collected by other stations. Conversely, with access to the internet, BlueNavi can also send data back to the land stations, enabling other ships to identify non-AIS ships as well. Through the live-ship test, we demonstrate that BlueNavi works well offline in cooperation with shipborne AIS equipment. We also look at some possible application scenarios for BlueNavi with other data sources and means of communication other than AIS and VHF that can be expanded to the platform. BlueNavi will enable inexpensive ship identification for small vessels and provide an extension of functionality to ECDIS for large ships. Full article

Due to the ever-increasing amount of data collected and the requirements for the rapid and reliable exchange of information across many interconnected communication devices, land-based communications networks are experiencing continuous progress and improvement of existing infrastructures. However, maritime communications are still characterized by slow communication speeds and limited communication capacity, despite a similar trend of increasing demand for information exchange. These limitations are particularly evident in digital data exchange, which is still limited to relatively slow and expensive narrowband satellite transmission. Furthermore, with the increasing digitalization of ships and introducing the sustainable concept of autonomous ship operation, large amounts of collected data need to be transmitted in real-time to enable remote voyage monitoring and control, putting additional pressure on the already strained means of maritime communications. In this paper, an adaptive shipboard data compression method based on differential binary encoding is proposed for real-time maritime data transmission. The proposed approach is verified on the actual data collected on board a training ship equipped with the latest data acquisition system. The obtained results show that the proposed data encoding method efficiently reduces the transmitted data size to an average of 3.4% of the original shipboard data, thus significantly reducing the required data transmission rate. Moreover, the proposed method outperforms several other tested competing methods for shipboard data encoding by up to 69.6% in terms of compression efficiency. Therefore, this study suggests that the proposed data compression approach can be a viable and efficient solution for transmitting large amounts of digital shipboard data in sustainable maritime real-time communications.
