Forest Monitoring and Wildland Early Fire Detection by a Hierarchical Wireless Sensor Network

A wildland fire is an uncontrolled fire that occurs mainly in forest areas,although it can also invade urban or agricultural areas. among the main causes of wildfires,human factors,either intentional or accidental,are the most usual ones. the number and impact of forest fires are expected to grow as a consequence of the global warming. in order to fight against these disasters,it is necessary to adopt a comprehensive,multifaceted approach that enables a continuous situational awareness and instant responsiveness. this paper describes a hierarchical wireless sensor network aimed at early fire detection in risky areas,integrated with the fire fighting command centres,geographical information systems,and fire simulators. this configuration has been successfully tested in two fire simulations involving all the key players in fire fighting operations: fire brigades,communication systems,and aerial,coordination,and land means. copyright © 2016 antonio molina-pico et al.
