The author proposes a hierarchical access control scheme using control sequence sets to address the challenges of differentiated access communication in data link networks.
Abstract
The paper introduces a hierarchical access control model based on control sequences for efficient and secure data transmission. It discusses theoretical bounds, construction methods, and performance evaluations of the proposed schemes.
The content emphasizes the importance of achieving collision-free node access and differentiated communication levels in wireless networks. Various existing methods are compared with the proposed hierarchical access control using control sequences.
Key points include the significance of time slots allocation, anti-interference properties, and random access for users with different levels. Theoretical bounds are derived to optimize hierarchical control sequence sets for maximum utilization of time slots.
Two constructions of optimal hierarchical control sequence sets are presented, focusing on even distribution within frames and random allocation between frames. Simulation results demonstrate improved anti-interference performance with longer sequences.
Overall, the paper provides insights into enhancing communication quality through hierarchical access control mechanisms in data link networks.
