Abstract
本发明公开了一种集中辅助初始化的LoRaWAN网络分布式资源分配方法在LoRaWAN网络中由网关节点执行集中辅助初始化过程，通过采集终端节点在不同信道上的链路状态信息构建终端节点‑信道质量矩阵，并据此对终端节点进行信道预分配，同时基于数据包传输成功率对扩频因子集合进行筛选，从而构建终端节点的有效扩频因子集合。在此基础上，各终端节点在本地执行分布式资源决策过程，对扩频因子和发射功率进行自适应选择与更新，并根据数据包传输结果对参数统计量进行递推更新。通过上述方法，将原始三维参数联合优化问题转化为二维参数优化问题，降低参数搜索空间，提高资源分配效率，在保证数据包传输成功率的同时降低终端能量消耗，适用于大规模LoRaWAN网络部署场景。
