A WSN-based maritime border alert system to protect fishermen

The safety of fisherman has become a big issue in Tamil Nādu because of fishermen invading the Sri Lankan border. This initiative primarily seeks to save fishermen's lives by tracking the location of their boats and alerting them to the boundary limit, which is then sent to the control centre. A pulse detector is also included, which aids in the monitoring of the fishermen's health. The concept is built around an embedded system that protects fisherman by alerting them to the country's border via a wireless sensor network (WSN) and a global mobile communication system (GSM). Each zone in the region has a different function, but they all have four things in common: they're all in the same general area. While fishing, if the fisherman ignores or fails to see the display, the alarm will go off, alerting him and slowing down the boat as it gets close to the forbidden zone. It includes a pulse oximeter as well; in case the user has any health issues. This information is sent to the command centre.
