A Cross-layer Design Scheme between Spectrum Decision and Routing in Cognitive Wireless Mesh Networks

摘要：

　　Spectrum sharing technologies can achieve the maximum usage of spectrum resources flexibly and high-efficiently,which relieves the current spectrum crunch situation availably.In a multi-hop cognitive wireless mesh network scenario coexisting with a TDMA/FDMA cellular network,an effective scheme of cross-layer design between link-layer spectrum decision and network-layer routing is proposed,on the basis of the combination of spectrum underlay and spectrum overlay.Simulation results verify that the scheme outperforms distinctly the shortest path based random spectrum decision algorithm on network end-to-end performance.
