Distributed Time Synchronization in NOMA-Assisted Ultra-Dense Networks
April 8, 2025
https://arxiv.org/pdf/2504.04195This research tackles the problem of synchronizing time across many small base stations (SBSs) in a dense network, a crucial aspect for technologies like 6G. It proposes a distributed approach where SBSs exchange timing information with neighbors to align their clocks, addressing the limitations of centralized methods that rely on GPS or have high overhead.
Key points for LLM-based multi-agent systems:
- Distributed Coordination: SBSs act as independent agents, exchanging information locally to achieve global synchronization, mirroring how multi-agent systems coordinate without central control.
- Information Exchange Delays: The research explicitly models and addresses communication delays, a crucial aspect of real-world multi-agent systems where message passing takes time.
- Resource Allocation Optimization: The use of Non-Orthogonal Multiple Access (NOMA) and stable matching algorithms optimizes the assignment of communication resources (sub-bands) to agents (SBSs), highlighting the importance of efficient resource management in multi-agent interactions.
- Dynamic Adaptation: The proposed algorithm iteratively refines both the SBS-SB scheduling and power allocation, enabling the system to dynamically adapt to changing network conditions and user demands, mimicking the adaptability required in complex multi-agent environments.
- Stability: The proven stability of the algorithm, ensuring convergence to a synchronized state, offers insights into designing robust multi-agent systems that reliably reach a desired global outcome despite decentralized control.
