摘　　要：随着互联网技术的不断提升,物联网使用范围逐渐扩大。在为人们的生活提供便利的同时,也出现相应的数据传输问题。针对传统物联网任务传输链路调度算法为设定网络数据传输顺序,造成物联网数据传输丢包率过高,网络资源利用率较低的问题,设计基于数据优先级的物联网任务传输链路调度算法。构建物联网任务传输链路模型,采用数据优先级技术设定优先条件,完成任务数据等级分化。采用任务优先级划分结果,结合DS-FP算法,并根据原有物联网任务传输链路调度过程,设计任务链路调度器。至此,基于数据优先级的物联网任务传输链路调度算法设计完成。构建算例测试环节,通过与其他两种算法对比可知,此算法可有效解决物联网数据传输丢包率过高,网络资源利用率较低的问题,实现对物联网的高效利用。综上可知,此方法调度能力更佳。With the continuous improvement of Internet technology,the use of Internet of things has gradually expanded.While providing convenience for people's life,there are also corresponding data transmission problems.Aiming at the problem of high packet loss rate and low utilization rate of network resources caused by the traditional task transmission link scheduling algorithm of Internet of things to set the network data transmission order,a task transmission link scheduling algorithm based on data priority is designed.Build the task transmission link model of the Internet of things,set the priority conditions by using data priority technology,and complete the task data level differentiation.The task link scheduler is designed based on the task priority division results,DS-FP algorithm and the original scheduling process of IOT task transmission link.So far,the design of task transmission link scheduling algorithm based on data priority is completed.By comparing with the other two algorithms,this algorithm can effectively solve the problem of high packet loss rate and low utilization rate of network resources in the Internet of things,and realize the efficient utilization of the Internet of things.In conclusion,the scheduling ability of this method is better.
