主要动机

• A novel framework is proposed for quality of experience driven deployment and dynamic movement of multiple unmanned aerial vehicles (UAVs).
• 过去研究大多没有基于用户的移动(movement of users)来考虑无人机的机动性，更多地是考虑多架无人机的二维部署或单架无人机在地面用户保持静止情况下的部署。
• 考虑QoE, 而不是仅考虑吞吐量(throughput)，即需要考虑地面不同用户的具体需求。(QoE is invoked for demonstrating the users’ satisfaction, and it is supposed to be considered in UAV-assisted wireless networks)
• 该文设计的是3D部署，过去研究主要考虑的是2D部署。
