Modelling D2D communications in cellular access networks via Coupled Processors
MetadatosMostrar el registro completo del ítem
Also in cellular networks, D2D communications provide numerous advantages. Nevertheless, modelling D2D systems remains a complex and unsolved task. In this work, we present the first analytical study on D2D system performance. Our approach models interdependencies among D2D and cellular transmitters in details and achieves a conservative estimation of the stability region of D2D systems, as well as evaluates the effects of D2D transmissions on cellular users. Furthermore, the proposed approach can easily tradeoff performances for less complexity in a realistic application, i.e., in a proportional fairness optimization.
