The Research of Cross-layer Design between the PHY and MAC Layer for OFDM-Based Cognitive Radio Network
Peng Yi, Zengli Liu, Hua Long, Jie Peng · 2009
In this paper we discuss a novel OFDM-based cognitive radio network (OFDM-based CRN) technique and motivations for cross-layer design in CRN, proposed a novel architecture in which the dynamic channel allocation is achieved by a cross-layer design between the PHY and MAC layers for OFDM-Based cognitive radio network. Simulation shows it can improve network performance.
