摘　　要：为解决移动物联网传输领域内存在的节点传输能力不强和网络覆盖能力较弱等不足,提出了一种基于节点沉默激活机制的移动物联网传输优化算法.首先,针对节点彼此之间的覆盖关系,在多个节点同时达到覆盖效果情况下设计了基于周期控制的节点沉默方法,以达到降低节点激活概率进而改善节点能耗的目的.随后,利用节点覆盖时的角度覆盖关系,采取剩余能量优化的方式设计了基于自感知机制的区域覆盖方法,该方法采用阈值控制节点沉默,进一步提高网络覆盖率,从而优化网络传输.仿真实验表明,本文算法能够有效提高网络覆盖率,增强节点传输能力,具有很强的实际部署价值.To solve the weakness of node transmission and network coverage in the mobile internet of things transmission field,a mobile internet of things transmission optimization algorithm based on node silent activation mechanism is proposed.First,for reasons of multiple nodes achieving the coverage effect at the same time,a node silence method based on periodic control is designed hoping to reduce the node activation probability and improve the energy consumption.Then,we base our analysis on an angle coverage relationship of node coverage.A region coverage method with a self-sensing mechanism is designed by residual energy optimization.The method uses a threshold to control node silence,further improve network coverage,and optimize network transmission.The simulation results show that the algorithm can effectively improve the network coverage and enhance the transmission capacity of nodes,which has a strong practical deployment value.
