Abstract: The current marine security challenge includes protecting fishermen and responding to illegal border infiltration. Using the Internet of Things (IoT), this study created a technique for enhancing border detection that largely leverages the Automatic Detection System (AIS) to determine the boundary for fishermen. Very High Frequency (VHF) communication, inspired by X-band radar, is integrated into the proposed idea to provide highly accurate boat detection in the middle of the sea. The system can recognize and track vessels at sea. The system architecture included VHF (Very High Frequency) communication, which was modeled after the X band radar system, to provide the middle sea with a high level of boat detection and monitoring. The breadth of AIS.
The suggested approach uses Very High Frequency (VHF) communication, which was influenced by X-band radar, to give highly accurate boat detection in the middle of the sea. Boats at sea can be detected and tracked by the system. Inspired by the X band radar system, the system architecture integrated VHF (Very High Frequency) transmission to give the middle sea a high level of boat detection and surveillance. VHF transmission was used to extend the AIS's range. Using IoT devices, fishing boats provide position and status data to the coastal monitoring stations. Fishing boats equipped with IoT-enabled devices are part of the new AIS technology. After sending data, the IoT devices installed aboard boats transmit information to the coastal monitoring station. In addition to the introduction of the Internet of Things (IoT), the Automatic Identification System (AIS) currently in use has been improved. As a result, the system can now communicate with marine vessels and track and monitor them in a far more thorough and real-time manner.
