摘要:

面向应急管理平台中感知网络缺少地面基站时的关键区域信息传输需求,考虑应急物联网节点空间定位存在的不确定性,提出基于无人机(UAV, unmanned aerial vehicle)的物联网空基中继鲁棒优化方法。首先,建立此类物联网的系统模型;其次,根据建立的非凸非线性模型与地面物联网终端设备定位精度存在较大关联,且定位信息的细微扰动可导致模型求解无效的实际情况,对系统模型进行了松弛并引入物联网设备定位数据的不确定性描述,进而得到低空域无人机中继通信功率优化问题的鲁棒对等模型;再次,给出了模型求解算法;最后,通过仿真实验,从无人机部署效果和通信功率控制等方面验证了本文所提方法的有效性和鲁棒性,同时,分析了影响本文所述方法效能的因素。

Abstract:

Faced with the need of key regional information transmission in the emergency situation where the perception network lacks of ground base stations, considered about the uncertainty of spatial positioning of emergency internet of things (eIoT) nodes, a robust optimization method for air-based relay of eIoT based on unmanned aerial vehicle (UAV) was proposed.Firstly, the system modeling of this kind of eIoT was carried out.Secondly, according to the fact that the non-convex and nonlinear model has a great correlation with the positioning accuracy of the ground-based eIoT equipment and the tiny disturbance of the positioning information can lead to the invalid solution of the model, the system model was relaxed and the uncertainty description of the location data of the eIoT equipment was introduced, Then the robust equivalent model of the low altitude UAV relay communication power optimization problem was obtained.Thirdly, the model solving algorithm was given.Finally, the effectiveness and robustness of the proposed method were verified from the deployment of UAV and communication energy consumption.At the same time, the factors effecting the effectiveness of the proposed method were analyzed.
