摘要：

针对认知容量收集网络中网络切片的频谱共享问题，提出了一种认知容量收集网络中网络切片频谱共享策略。通过建立4D冲突图模型，提出了无冲突节点集的求解方法，并建立了频谱共享的机会容量模型，推导了非授权信道的机会容量，联合4D冲突图模型和机会容量模型提出了一种认知容量收集网络中网络切片频谱共享策略。仿真结果表明，与现有算法相比，所提算法能有效利用机会频谱资源，进一步提高信道利用率。

Abstract:

To realizing the network slice with spectrum sharing in cognitive capacity harvesting network, a spectrum sharing strategy was proposed based on 4D conflict graph and opportunistic capacity.Firstly, a 4D conflict graph model for mesh network was built and a method to achieve the node sets with conflict free was proposed.Then, the opportunistic capacity model of spectrum sharing was established and the opportunistic capacity of the unlicensed channel was derived.Finally, the spectrum sharing strategy based on 4D conflict graph and opportunistic capacity was proposed for cognitive capacity harvesting network.The simulation results show that compared with existing algorithms, the proposed algorithm can effectively utilize opportunistic spectrum resources and further improve channel utilization.

Key words: cognitive capacity harvesting network, network slicing, spectrum sharing, conflict graph model
