This document describes an IoT-based system to alert fishermen if they cross maritime borders and enter restricted areas. The system uses GPS to track the location of fishing boats and wireless sensor networks to transmit location data. If a boat crosses the border, an alarm will sound and the boat's engine will reverse to prevent entry into restricted waters. The system aims to safeguard fishermen's lives by alerting them and coastal authorities if boats enter areas where they could be detained by neighboring countries.
