摘要:

无人机(无人机)通常作为移动汇点被派遣,以协助大规模无线传感器网络(WSNs)中的数据汇集。然而,当考虑到大规模WSN中UAV的移动性和通信能力的限制时,一些传感器节点可能会耗尽存储空间,因为它们无法在延长的时间段内将其数据卸载到UAV。为了最大限度地减少数据丢失所造成的上述问题,联合用户调度和轨迹规划数据汇集策略,提出了这封信,这是制定为一个非凸优化问题。该问题被进一步分解为两个子问题并依次求解。仿真结果表明,该策略在最小化数据丢失率方面比其他策略更有效。

英文摘要:

Unmanned aerial vehicles (UAVs) are usually dispatched as mobile sinks to assist data collection in large-scale wireless sensor networks (WSNs). However, when considering the limitations of UAV's mobility and communication capabilities in a large-scale WSN, some sensor nodes may run out of storage space as they fail to offload their data to the UAV for an extended period of time. To minimize the data loss caused by the above issue, a joint user scheduling and trajectory planning data collection strategy is proposed in this letter, which is formulated as a non-convex optimization problem. The problem is further divided into two sub-problems and solved sequentially. Simulation results show that the proposed strategy is more effective in minimizing data loss rate than other strategies.
