摘    要:利用无线传感器网络进行森林火灾预警和火灾现场定位可以有效预防火灾发生或在其发生后尽早得知其位置.提出了一种基于分簇的DPE定位算法,该算法根据DPE算法的递增思想进行分簇,并同步进行节点定位,从而提高系统定位的准确度和网络的可扩展性以及实时性.仿真结果表明:在允许定位误差小于5 m时,节点定位的准确率可达97%.

关 键 词:无线传感器网络  森林防火  节点定位  DPE算法  边界节点

Abstract:Using the wireless sensor networks to predicate the forest fires and locate the fire scene can prevent forest fires effectively or get the position as soon as possible.A DPE location algorithm which based on cluster is proposed.It clusters according to the incremental thinking of the DPE algorithm,and locates nodes simultaneously,so as to improve the accuracy of system positioning and network scalability and real time.Simulation result show when the allowable positioning error is within 5m,node positioning ...
Keywords:wireless sensor networks(WSNs)  prevention of forest fires  node location  DPE algorithm  border nodes
