基于能量采集的管道物联网路由优化算法

油气管道无线传感器网络的节点根据管道走向呈线性分布,导致无法及时大范围更换能量耗尽节点的电池.虽然能量有效管理始终是制约油气物联网性能的关键因素,但因网络端对端延时决定网络对管道安全事故的反应时间,同样是影响网络性能的关键参数之一.为此,提出基于能量采集的管道物联网网络路由算法,使用能量采集技术,延长网络的使用寿命,并通过选择距离发送较远的节点作为转发节点,有效减少网络的端对端延时.仿真结果表明,与其他机会路由协议和使用能量采集技术的协议对比,该算法能有效兼顾网络寿命和网络延时,提高网络性能.

Wireless Routing Optimization Algorithm for Pipeline Internet of Things Based on Energy Acquisition

The nodes of wireless sensor networks for oil and gas pipelines are linearly distributed according to the pipeline direction. It is unable to replace the batteries of the energy exhausted nodes in a large scale in time.Effective energy management has been a key factor restricting the performance of the oil and gas Internet of things. Network end-to-end delay determines the response time of network to pipeline accidents, so it is also a key parameter. The routing algorithm proposed in the paper uses energy acquisition technology to extend the service life of the network. The end-to-end delay of the network can be effectively reduced by selecting the node which is far away from the sender as the forwarding node. Simulation results show that the algorithm can effectively consider network lifetime and network delay, and improve network performance compared to other opportunistic routing protocols and protocols using energy harvesting technology.
