A Wireless Sensor Network-Based Safety System for Fishermen. Fishermen often face significant risks due to adverse weather conditions, equipment failures, and unforeseen emergencies at sea. To address these challenges, this research proposes a novel safety system that leverages Wireless Sensor Network (WSN) technology. The proposed system comprises a network of sensors strategically deployed on fishing boats and in the surrounding waters. These sensors collect critical data such as GPS location, temperature, humidity, barometric pressure, water depth, and potential hazards like strong currents or underwater obstacles. The collected data is transmitted wirelessly to a central monitoring station, where it is processed and analyzed using advanced algorithms. The central monitoring station continuously monitors the real-time data to identify potential risks. In case of an emergency, such as a boat capsizing, a distress signal is automatically triggered and transmitted to emergency response teams and the fishermen's families. The system can also provide early warnings about impending storms, tsunamis, or other natural disasters. Additionally, the system can be used to optimize fishing operations by providing valuable insights into fish stocks, water quality, and optimal fishing zones. By collecting data on fish behavior and migration patterns, fishermen can make informed decisions about where and when to fish, maximizing their catch while minimizing their environmental impact. The proposed WSN-based safety system has the potential to significantly enhance the safety of fishermen, reduce fatalities, and improve the overall efficiency and sustainability of the fishing industry. By integrating advanced technology with traditional fishing practices, this system aims to create a safer and more prosperous future for fishing communities.
