Summary
This study introduces a Cognitive Radio Sensor Network (CRSN) for early forest fire detection. The system uses IEEE 802.11af to ensure reliable, low-latency emergency alerts, overcoming traditional network limitations.
Area of Science:
- Environmental Science
- Computer Engineering
- Telecommunications
Background:
- Forest fires pose significant ecological and economic threats, necessitating rapid detection.
- Conventional wireless sensor networks struggle with timely alerts in forest environments due to congestion and unreliable channels.
Purpose of the Study:
- To propose a Cognitive Radio Sensor Network (CRSN) for an effective Forest Fire Early Warning and Emergency Notification System.
- To address the limitations of traditional networks in delivering urgent alerts during forest fire events.
Main Methods:
- Integration of temperature, smoke, and gas sensors with cognitive radio sensor nodes.
- Utilization of IEEE 802.11af technology for dynamic sensing and use of idle licensed channels.
- Implementation of Adaptive Priority Management for prioritizing emergency alert classes.
Main Results:
- The proposed CRSN system demonstrates lower bit error rates compared to conventional methods.
- Reduced latency in emergency alert transmissions was observed under various environmental conditions.
- Enhanced reliability and effectiveness in forest fire emergency notifications were achieved.
Conclusions:
- The CRSN system effectively bypasses network congestion by utilizing dynamic spectrum access.
- The proposed system ensures low-latency and reliable delivery of critical fire alerts.
- This technology significantly improves forest fire early warning and emergency notification capabilities.
