A Novel Spatial Dynamic Spectrum Allocation in the Urban Heterogeneous Scenario
Based on the research of spatial traffic distribution model in urban areas, this paper presents a novel urban spatial Dynamic Spectrum Allocation (DSA) according to the characteristics of spatial spectrum demand distribution in urban areas. A dynamic DSA area division method is investigated, which sets up a new neighboring relationship among the DSA areas. So part of the available spectrum is released from the heterogeneous interference limit, and the spatial DSA is conducted in a more flexible way with better performance. Simulative comparison demonstrates that the proposed urban spatial DSA in this paper outperforms the conventional spatial DSA in terms of spectrum satisfaction.
