面向低时延服务的非正交多址接入与反向散射通信融合边缘计算网络设计与优化
Design and optimization of NOMA-backscatter integrated edge computing networks for low-latency services
摘要
Abstract
In large-scale IoT access scenarios,limited terminal computing resources and interference-prone communica-tion links made it difficult to guarantee low-latency services.A mobile edge computing(MEC)architecture that inte-grated non-orthogonal multiple access(NOMA)and backscatter communication was proposed to enhance task offload-ing efficiency and reduce transmission delay.A joint optimization model was formulated to minimize total delay by opti-mizing task allocation,backscatter coefficient,and energy station power,subject to energy,latency,and computing con-straints.A block coordinate descent-based algorithm was developed,where sub-problems were solved via interior-point and convex approximation methods.Simulation results verify that the proposed scheme outperforms conventional MEC systems using only NOMA or backscatter communication in reducing delay and improving efficiency.关键词
