Current IoT communication node spacing selection process show may potential areas for improvements such as high delay ratio, high total energy consumption ratio, confusion of the optimal communication information band, intelligent spacing node design under the constraints of the energy-saving selection of IoT communication. Based on energy-saving constraints, the link status between nodes is evaluated through link stability and link quality. In order to prevent the generation of serious noisy nodes and frequency hopping data, the interference nodes under the intrusion of the Internet of Things are identified by determining transition amplitude of the noise nodes in the transmission data sequence. Finally, according to the calculation results of the optimal communication node selection, the design of the intelligent spacing selection model for the communication nodes of the Internet of Things is realized. The simulation results show that the established model not only reduces energy consumption of nodes, shortens the average transmission delay of nodes, but also improves anti-interference effect of node spacing selection.

当前的物联网通信节点间距选择过程表明，在物联网通信节能选择的约束下，可能存在诸如高延迟比、高总能耗比、最优通信信息频带混乱、智能间距节点设计等改进的潜在领域。基于节能约束，通过链路稳定性和链路质量来评估节点之间的链路状态。为了防止产生严重的噪声节点和跳频数据，通过确定传输数据序列中噪声节点的跃迁幅度来识别物联网入侵下的干扰节点。最后根据最优通信节点选择的计算结果，实现了物联网通信节点智能间距选择模型的设计。仿真结果表明，所建立的模型不仅降低了节点的能耗，缩短了节点的平均传输时延，而且提高了节点间距选择的抗干扰效果。
