面向林火监测的无线传感器布局规划模型

Wireless Sensor Layout Planning Model for Forest Fire Monitoring

针对林火监测无线传感器的特点,基于遗传算法建立一个传感器规划模型.该模型在规划过程中通过考虑林区地形、传感器信号范围和信号穿透力等因素,根据所使用的传感器个数和覆盖度要求等约束条件终止算法,其收敛速度和迭代次数可控,可用于地形变化较大的林区火险监测传感器的布局规划,用尽可能少的传感器满足对林区的覆盖度要求.

The authors established a sensor programming model based on the genetic algorithms with the characteristics of a wireless sensor taken into account for forest fire monitoring.During the planning,forest terrain,the sensor signal range,the signal penetration and other factors were considered,and algorithm was terminated according to the limiting number of sensors and coverage requirements.Its convergence speed and the number of iterations are controllable.This model can be used for planning the layout of forest fire monitoring sensors that are used in forest with undulating terrain,with as little sensors meet the requirements of coverage.
