Abstract(s)
Every year forest fires destroy millions of hectares of land worldwide. Detecting forest fire
ignition in the early stages is fundamental to avoid forest fires catastrophes. In this approach, Wireless
Sensor Network is explored to develop a monitoring system to send alert to authorities when a fire
ignition is detected. The study of sensors allocation is essential in this type of monitoring system
since its performance is directly related to the position of the sensors, which also defines the coverage
region. In this paper, a mathematical model is proposed to solve the sensor allocation problem. This
model considers the sensor coverage limitation, the distance, and the forest density interference in
the sensor reach. A Genetic Algorithm is implemented to solve the optimisation model and minimise
the forest fire hazard. The results obtained are promising since the algorithm could allocate the sensor
avoiding overlaps and minimising the total fire hazard value for both regions considered.
