摘要: 在物联网环境中,网络需要传输的数据和信息量急剧增加,从而造成带宽不足。为此,提出一种采用动态带宽资源分配算法的物联网远程机械控制方案,通过改变控制信号的采样速率,达到优化分配带宽资源的目的。仿真结果表明,在相同网络带宽条件下,该方案可降低重构信号的误差,并有效提高物联网系统智能分配带宽资源的能力。

Abstract: According to the booming increase of network transmitted data or information and the corresponding network bandwidth insufficiency caused by the popularization of Internet of Things(IoT) key supporting technologies, such as cloud computing and data mining, this paper proposes an IoT remote machine control scheme based on a novel dynamic bandwidth resource allocation algorithm, which optimizes the bandwidth usage by scheduling the sampling rates of the control signals. Simulation results show under the same network bandwidth condition, this algorithm can reduce the reconstruction signal’s error as well as enhance the intelligent bandwidth allocation capability in IoT system.
