森林火灾监测无线传感器网络有效路由算法

Efficient Routing Algorithm in Forest Fire Monitoring Wireless Sensor Network

针对森林火灾监测系统必须满足能耗低的特点,论文提出一种有效的簇头选择方法。该方法以剩余能量为基准设计簇头,同时,由于森林环境网络拓扑结构动态变化,在簇头选择过程中考虑节点的网络拓扑位置。对于能量异构网络而言,如果某节点占有能量优势,让其连续成为簇头或某几个节点轮流成为簇头,避免每轮簇头的选择。理论分析和仿真结果表明,该算法有效平衡节点间能耗,降低算法开销,延长网络生命周期。

In order to improve the performance of forest fire warning system,an effective routing algorithm is proposed.Based on the residual energy,the cluster head is designed.At the same time,due to the forest environment,the network topology is dynamic,the node position is considered in the process of cluster head selection.For the energy heterogeneous network,if a node has much energy,it can become a cluster head or a few nodes alternately to be cluster head.Theoretical analysis and simulation results show that the algorithm is effective balance between energy consumption of nodes,the algorithm reduces the overhead and prolongs the network life cycle.
