  • 摘要: 在无人机(UAV)辅助的能量受限低功耗物联网(IoT)节点数据传输场景中,针对传统的Matérn聚类过程 (MCP)建模造成的无人机覆盖冗余问题,该文提出一种Matérn集群下的距离约束分簇策略(MCDC)。该策略采用带有距离约束的Matérn聚类过程对无人机和地面IoT节点位置进行了建模,实现冗余覆盖的大幅度下降。在此分布策略下,IoT节点首先通过从无人机发送的射频信号中收集能量,然后利用收集的能量向无人机进行上行数据传输,解决IoT节点能量受限问题。此外,分析了IoT节点传输机会以及无人机群空地网络的上行传输中断性能和吞吐量,并衡量了上下行阶段的时间分配比,无人机的发射功率,以及IoT节点密度等参数对网络性能的影响。最后通过仿真对理论结果进行了验证。
