基于智能分析的分布式频谱共享技术研究
Distributed spectrum sharing technology based on intelligent analysis
摘要
Abstract
Secondary Users(SUs)use the Channel Hopping(CH)sequences to sharing dynamic spectrum is one of the solution to the problem in spectrum sharing for distributed Cognitive Radio Networks(CRN). In this type of spectrum sharing, SUs tune themselves to the idle channels following predetermined CH sequences, and realize rendezvous with each other during this process. According to the characteristics of distributed CRN, this paper proposes a super frame under MAC protocol for rendezvous operation which has the aim of getting better system performance. An intelligent spectrum database is proposed to store the spectrum sensing results and the channel occupancy history. The database is used to support the actions of channel accessing for SUs. Simulation results show that the proposed MAC protocol can get a better comprehensive performanceunder high traffic conditions.关键词
