基于CSI特征的异构执行体动态调度算法OA

In the current mimetic authentication scenario based on channel state information(CSI),existing dynamic scheduling algorithms suffer from insufficient authentication performance due to inadequate consideration of the heterogeneity of execution entities.This paper proposes a CSI features-based heterogeneous executor dynamic scheduling algorithm(CF-HEDA).The algorithm comprehensively quantifies the correlation between CSI features and the heterogeneity of execution entities to construct a feature-based heterogeneous execution entity matrix.Based on this,the algorithm integrates dynamic historical threat assessment with an iterative greedy strategy to prioritize maximizing feature coverage.It selects execution entities by integrating a comprehensive score that considers contributions from heterogeneity,historical risk,and failure indices.Through attack collision simulation experiments,this paper compares four algorithms,including the high-order heterogeneous scheduling algorithm(HFAWA).The experiments demonstrate that under different numbers of execution entities,CF-HEDA consistently achieves the best performance,with average defense success rates and average attack interception rates improved compared to existing algorithms,and overall performance enhanced by approximately 5％to 12％.
