【摘要】：在对铀尾矿库进行监测时,无线传感器优于传统的有线布置,但由于能量受限,在路由传输中必须高效地使用能量。该文在分析LEACH和GAF算法的基础上,提出了一种基于GAF交圆结构的改进型路由算法(IC-GAF)。利用节点地理位置信息与相交圆的结构模型来划分虚拟圆,在虚拟圆内根据剩余能量和节点与中心的距离来选举簇头,簇头从下一接收簇头或中转节点中选择最优的下一跳节点传输数据,最终将数据传输到基站。仿真表明,IC-GAF能有效的降低节点能耗,延长网络寿命。
[Abstract]:The wireless sensor is superior to the traditional wired arrangement in monitoring uranium tailings, but the energy must be used efficiently in routing transmission because of the limited energy.In this paper, based on the analysis of LEACH and GAF algorithms, an improved routing algorithm based on GAF intersecting circular structure is proposed.The virtual circle is divided into virtual circles by using the structure model of node location information and intersecting circle. Cluster heads are selected according to the residual energy and the distance between node and center in the virtual circle.The cluster head selects the optimal next hop node to transmit data from the next receiving cluster head or transfer node, and finally transmits the data to the base station.Simulation results show that IC-GAF can effectively reduce node energy consumption and prolong network life.
