Research on Key Technologies of Resource Management of Internet of Things Based on Cellular Narrowband

蜂窝窄带物联网技术是信息化进程的里程碑,其中NBIoT技术因其成本低、连接多、覆盖广等优势受到了广泛的关注.本文将网络中业务分为两种形式:正常业务报告,应用分阶段调度算法来优化资源调度;在异常报告业务中,通过改进了RU度量值的计算方式、基于“RU连续性”优化子载波个数来优化资源调度.仿真实验结果表明,本文设计的算法可以较好地提升系统吞吐量.

Narrowband cellular Internet of things(nbiot)technology is a milestone in the process of informatization.Nbiot technology has been widely concerned for its advantages of low cost,multiple connections and wide coverage.In this paper,the network services were divided into two forms:normal service report,using phased scheduling algorithm to optimize resource scheduling;in exception reporting service,by improving the calculation method of Ru metrics,optimizing the number of subcarriers based on"Ru continuity"to optimize resource scheduling.Simulation results showed that the proposed algorithm could improve the system throughput.
