摘　　要：在恶劣的环境下传感器节点能量限制一直是制约油气管道物联网性能的关键因素。网络端对端延时决定了油气管道物联网对于管道安全事故的反应时间。为此,针对油气管道物联网能量限制和端对端延时问题提出基于多目标优化的管道物联网无线路由算法,通过将节点剩余能量以及节点到汇聚节点之间的距离作为机会路由中选择候选转发节点的指标,实现了物联网中能量的均衡,通过减少数据传输跳数,达到减少网络端对端延时的目的。仿真结果表明,与经典机会路由算法相比,该算法能有效兼顾网络寿命和网络延时改善网络性能,不仅能使网络获得较长的使用周期,还能减少油气管道物联网对安全事故的反应时间。The energy limitation of sensor nodes is the key factor to restrict the performance of the oil and gas pipeline Internet of things.The end-to-end delay of the network determines the response time of the oil and gas pipeline Internet of things to pipeline accidents.For solving the problems of energy limitation and end-to-end delay,the pipeline internet of things wireless routing algorithm based on multi-object optimization is proposed.It can realize the energy balance of the Internet of things by taking the remaining energy of nodes and the distance between nodes and aggregation nodesas the index of selecting candidate forwarding nodes.The end-to-end delay of the network is reduced by decreasing the number of data transmission hops.The simulation results show that the routing algorithm can effectively improve the network performance by extending the network life and reducing the network delay compared to the classical opportunistic routing algorithm.
