先谈后谈:通过分布式频谱分类技术实现分布式动态频谱接入

Consensus-Before-Talk: Distributed Dynamic Spectrum Access via Distributed Spectrum Ledger Technology

Hyowoon Seo, Jihong Park, Mehdi Bennis, Wan Choi

摘要:

本文提出了一种由分布式账本技术(DLT)利用的频谱礼仪架构--先讨论后讨论(CBT)。在CBT中,二级用户的频谱接入请求以分布式方式达成共识,从而实现无冲突的分布式动态频谱接入。为了达成这种共识,次用户需要为额外的请求交换延迟付费。在考虑共识延迟的基础上,研究了CBT协议下的端到端延迟。延迟分析和数值评估都验证了所提出的CBT实现了较低的端到端延迟,特别是在严重的二级用户流量下,与先听后说(LBT)基准计划相比。

英文摘要:

This paper proposes Consensus-Before-Talk (CBT), a spectrum etiquette architecture leveraged by distributed ledger technology (DLT). In CBT, secondary users' spectrum access requests reach a consensus in a distributed way, thereby enabling collision-free distributed dynamic spectrum access. To achieve this consensus, the secondary users need to pay for the extra request exchanging delays. Incorporating the consensus delay, the end-to-end latency under CBT is investigated. Both the latency analysis and numerical evaluation validate that the proposed CBT achieves the lower end-to-end latency particularly under severe secondary user traffic, compared to the Listen-Before-Talk (LBT) benchmark scheme.
