摘要
无线传感网络(Wireless Sensor Networks,WSNs)已成为物联网(Internet of Things,IoT)的基石。然而,能耗成为阻碍WSNs应用拓展的绊脚石。为此,面向WSN-物联网,提出能效的簇路由(Energy-Efficient Clustering Routing,EECR)。EECR路由先利用象限四分树和二叉树分割算法将网络进行分割,再通过基于权重的簇头选择算法在每个分割区内产生一个簇头,并形成簇。随后,簇头利用模糊逻辑算法调整簇成员的休眠时隙,进而控制节点能耗。仿真结果表明,提出的EECR路由有效地降低能耗,提高了数据包传递率。
Wireless Sensor Networks(WSNs)have become the cornerstone of the Internet of Things(IoT).However,energy consumption has become a stumbling block to the application expansion of WSNs.Therefore,energy-efficient Clustering Routing(EECR)is proposed for WSN-internet of things.The EECR routing firstly use quad Tree and binomial tree partitioning algorithms to partition the network,and then generates a cluster head in each partition region through a weighted cluster head selection algorithm and forms a cluster.Then,the cluster head used the fuzzy logic algorithm to adjust the sleep slot of the cluster members,and then controls the energy consumption of the nodes.Simulation results show that the proposed EECR routing can effectively reduce energy consumption and improve packet delivery rate.
