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.
