摘  要:Device-to-device(D2D)communication underlay cellular networks offers several benefits,including offloading cellular traffic and improving throughput.In this paper,a scheme is proposed for D2D communication underlay cellular networks,by taking resource allocation algorithm into account.Firstly,a scenario where cellular users(CUs)and D2D users(DUs)coexist is considered.To characterize the clustering feature of DUs,the locations of CUs and DUs are modeled as Poisson cluster processes(PCPs),and the locations of base stations(BSs)are modeled as a Poisson point process(PPP).Subsequently,a resource allocation algorithm is proposed to allocate resources for CUs to DUs in the cluster,which involves the optimization of matching between D2D user and cellular user.Finally,the coverage probability of the clustering network is analyzed.The simulation results indicate that the proposed scheme can effectively enhance system capacity and reveal the effects of various parameters on system performance.
