基于双簇头的油气物联网节能路由算法

Energy-Efficient Routing Algorithm for Oil and Gas IoT Based on Dual Cluster Heads

为延长油气物联网寿命,提出一种基于双簇头的油气物联网路由算法。该算法在簇头选举过程中充分考虑了传感器节点当前剩余能量、历史平均能量、节点与基站的距离、邻居节点密度以及节点与能量收集源的距离等因素,并在同一簇群中选举双簇头,同时在数据传输阶段提出一种新型路由方式以均衡簇头能耗。在引入能量采集技术的同时,采用了一种新型的节点工作模式切换策略。仿真实验表明,与传统算法相比,该算法能更有效地均衡网络能耗,延长网络寿命。

To extend the lifetime of oil and gas IoT(Internet of Things),a dual cluster head based oil and gas IoT routing algorithm is proposed.The algorithm fully considers the current residual energy of sensor nodes,historical average energy,distance between nodes and base stations,density of neighboring nodes and distance between nodes and energy harvesting sources in the cluster head election process,and elects dual cluster heads in the same cluster,while proposes a novel routing method to balance the energy consumption of cluster heads in the data transmission phase.A novel node working mode switching strategy is adopted along with the introduction of energy harvesting techniques.Simulation experiments show that the algorithm can balance the network energy consumption more effectively and extend the network lifetime compared with the traditional algorithm.
