Spectrum Coordination Protocol for reconfiguration management in cognitive radio network
Hang Qin, Yanrong Cui · 2009 IEEE Youth Conference on Information, Computing and Telecommunication · 2009
This paper proposes a novel reconfiguration management scheme to dramatically improve spectral efficiency and performance in cognitive radio networks. It is very suitable for efficient wireless services in dense spectrum environment. A specific distributed spectrum etiquette protocol called ASCP (Adaptive Spectrum Coordination Protocol) is designed and analyzed. With proposed opportunistic collaboration scheme, flexible PHY/MAC and cross-layer capabilities with discovery and multi-hop routing is studied. The reconfiguration architecture is identified for selecting from a number of potential configurations to fulfill the communication requirements of a multi-hop network. The experimental results show that the proposed ASCP protocol with reconfiguration can achieve high bit-rate and end-to-end QoS guarantees.
