Energy-saving optimization strategy of Wireless Communications for Internet of things based on UAV

无人机具有高机动性等特点,在提高物联网通信性能方面有着巨大的潜力。针对无人机与物联网传感器节点之间的能量权衡,对基于无人机的无线通信系统的节能优化策略进行研究。该策略对物联网常用的圆形轨迹下无人机数据采集系统的性能进行分析,推导出无人机和传感器节点的能耗表达式,然后找出两者之间实现不同Pareto最优的传感器节点发射功率,找到地面节点与UAV通信中的能量折中关系,并使用仿真实验验证该策略的可行性和有效性。

UAVs have the characteristics of high mobility and have great potential in improving the communication performance of the Internet of Things.Aiming at the energy trade-off between UAV and IoT sensor nodes,the energy-saving optimization strategy of UAV-based data acquisition system is studied.This strategy analyzes the performance of the UAV data acquisition system under the circular trajectory commonly used in the Internet of Things,derives the energy consumption expression of the UAV and the sensor node,and then finds the sensor that achieves the best Pareto between the two The node launch power and the optimized flight trajectory of the UAV,and simulation experiments are used to verify the feasibility and effectiveness of the strategy.
