摘要:为了实现服务器对海量传感数据的快速收集,提出了一种基于空中计算的快速传感数据汇聚方案。该方案通过无线功率传输激励用户参与群智感知,为数据感知和空中计算供能。通过对无线功率分配、感知数据量,以及空中计算数据汇聚时间进行联合优化,实现服务器数据开发效益的最大化。该方案的性能将通过仿真进行验证,并与传统的无线群智感知设计进行比较。

Abstract: To achieve fast aggregation of massive sensing data at the server, an over-the-air computation (AirComp) based fast data aggregation design is proposed. In this design, wireless power transfer serves as the incentivizing mechanism for users to take part in wireless crowd sensing (WCS), as well as the energy source for data sensing and AirComp. The wireless power transfer allocation, sensing data size, and AirComp-based data aggregation time are jointly optimized to maximize the data exploitation reward of server. The simulation demonstrates the performance of the proposed design compared with the traditional WCS.
  Keywords: wireless crowd sensing; over-the-air computation; wireless power transfer
