Performance Analysis of Resource Allocation Schemes in Device-to-Device Communications with Bursty Traffic

Device-to-device (D2D) communication has been widely studied in academic and industry due to its contribution in improved resource utilization. As the radio resource can be reused by multiple D2D links, complicated intracell interference environment is caused. In this paper, we analyze the performance of resource allocation schemes in D2D communications, considering the dynamic data arrival with finite buffer. A queuing model under every resource allocation scheme is formulated. Specially, we model the interference relationship among different D2D links as a proposed interference graph, trying to ensure the spectral efficiency while controlling the interference within a certain range. We compare the performance of resource allocation schemes in terms of mean throughput and dropping probability. Simulation results are conducted to demonstrate the pros and cons of the proposed scheme.
