An AoI-oriented Time-Frequency Distributed Access Mechanism in Wireless Sensor Networks with Spectrum Division

The increasing adoption of spectrum-division techniques enables concurrent uplink transmissions over multiple orthogonal resources, yet low-overhead access design with effective information freshness remains insufficiently studied for large-scale randomly activated sensor networks. In this paper, we apply the age of in...

An LLM-Agent-Based Framework for Age of Information Optimization in Heterogeneous Multiple Access Networks

Reflex-Core is proposed, an LLM-agent-based framework for AoI-oriented adaptive access in heterogeneous wireless networks that adopts an “Observe-Reflect-Decide-Execute” closed-loop mechanism to refine transmission strategies through semantic feedback and historical memory and develops the Reflexive Multiple Access pro...
