18825 移动边缘计算(MEC)中计算卸载决策可能暴露用户特征,导致用户被锁定。 The decision on computation offloading to Mobile Edge Computing (MEC) may expose user’s characteristics and cause the user to be locked.
18826 针对此问题,该文提出一种基于Lyapunov优化的隐私感知计算卸载方法。 A privacy-aware computation offloading method based onLyapunov optimization is proposed in this paper.
18827 首先,该方法定义卸载任务中的隐私量,并引入隐私限制使各MEC节点上卸载任务的累积隐私量尽可能小; Firstly, the privacy of task is defined, and privacy restrictionsare introduced to minimize the cumulative privacy of each MEC node;
18828 然后,提出假任务机制权衡终端能耗和隐私保护的关系,当系统因隐私限制无法正常执行计算卸载时,在MEC节点生成虚假的卸载任务以降低累积隐私量; Then, the fake task mechanism is proposed to balance the terminal energy consumption and privacy protection, reducing the cumulative privacy of MEC node by generating a fake task non-feature task when offloading is not performed due to privacy restrictions;
18829 最后,建立隐私感知计算卸载模型,并基于Lyapunov优化原理求解。 Finally, the privacy-aware computing offloading decision is modeled and solved based on theLyapunov optimization.
18830 仿真结果表明,基于Lyapunov优化的隐私感知卸载算法(LPOA)能使用户的累积隐私量稳定在0附近,且总卸载频率与不考虑隐私的决策一致,有效保护了用户隐私,同时保持了较低的平均能耗。 Simulation results validate that the Lyapunov optimization-based Privacy-awareOffloading Algorithm (LPOA) can stabilize user’s privacy near zero, and the total offloading frequency is consistent with the decision that don’t consider privacy, effectively protecting user’s privacy while maintaining a low average energy consumption.
18831 为根本消除欠采样宽频谱分析中的伪峰副效应,该文提出基于并行全相位点通滤波的高性能互素谱分析方法。 In order to completely remove the spurious-peak side effect in the undersampling based wide-bandspectral analysis, this paper proposes a high-performance co-prime spectral analysis method based on paralleledall-phase point-pass filtering.
18832 通过剖析经典互素谱分析的机理,指出产生伪峰效应的根源在于上、下通道的多相滤波支路之间存在多余的重叠边界频带。 On basis of a deep analysis on the mechanism of the classical co-prime spectralanalysis, it is discovered that this spurious-peak side effect arises from those redudant overlapping boundary-bands related to distinct polyphase filtering branches between the up data path and the down data path.
18833 故借助全相位点通滤波器组来取代经典互素谱的原型滤波器,并且推导出基于并行点通滤波的互素谱分析流程。 Therefore, through replacing the prototype filters in the classical co-prime spectral analysis by the all-phasepoint-pass filtering banks, a novel co-prime analysis dataflow is derived based on paralleled all-phase point-passfiltering.
18834 理论分析和仿真实验均表明,新的方法显著改善谱分析性能:不仅从根本上消除了伪峰产生的可能,而且相比于经典互素谱分析还大大提升了谱分辨率,从而具有较高的密集谱成分辨识性能。 Both theoretic analysis and numerical simulation show that the proposed spectral analysis methodachieves remarkable performance improvement: it can not only completely remove the spurious-peak side effect,but also obtain a much higher spectral resolution than the classical co-prime analysis, thereby possessinganother merit of distinguishing dense spectral components.
