摘　　要：针对电力物联网通信传输时延、传输效率低的问题,文章提出一种低时延通信路由优化方法。首先,以总传输时延作为优化目标,采用基于接入网与核心网带宽联合优化的低时延路由传输进行业务路由资源优化。结果表明,随着时延敏感型业务数据包的增大,相较于均分带宽方案,提出的联合带宽优化方法的平均传输时延降低60.7%,传输效率明显更高;在不同数据包大小下,相较于单任务传输和均分任务传输策略,提出的多路径任务传输策略的时延平均降低37.18%和18.8%。由此说明,文章提出的方法可降低电力物联网传输时延时间和电网运营成本,提升电网数据传输性能和时延传输效率。A low latency communication routing technology based on the power Internet of Things is proposed to address the issues of prolonged communication transmission time and low transmission efficiency in the power Internet of Things.Firstly,with the total transmission delay as the optimization objective,a low latency routing transmission method based on joint optimization of access network and core network bandwidth is adopted to optimize business routing resources.The simulation results show that with the increase of delay sensitive business data packets,the average transmission delay of the proposed joint bandwidth optimization method is reduced by 60.7%compared to the uniform bandwidth scheme,and the transmission efficiency is significantly higher.Under different packet sizes,the proposed multipath task transmission strategy reduces the average latency by 37.18%and 18.8%compared to single task transmission and equal task transmission strategies.This indicates that the proposed method can reduce the transmission delay time and operation cost of the power Internet of Things,and improve the data transmission performance and delay transmission efficiency of the power grid.
