Abstract
En 中文
We investigate the performance of the simultaneous wireless information and power transfer (SWIPT)-enabled mobile networks, based on a novel coverage area-based coordinated multipoint transmission (CA-CoMP) technique. In particular, the proposed scheme exploits the cooperation technique by appropriately defining the set of cooperative base stations, aiming at reducing the handover rate of the SWIPT-enabled battery-operated mobile users (MUs). Using stochastic geometry tools, we first establish an analytical and tractable framework to investigate the achieved information decoding and energy harvesting performance of the proposed scheme, in terms of the coverage probability, the average spectral efficiency and the average harvested energy. Moreover, analytical expressions for the inter- and intra-cell handover rates are derived. Our results indicate the ability of our proposed scheme to significantly reduce the handover rate of MUs. Finally, simulation results verify that the CA-CoMP scheme achieves a higher average spectral efficiency and a higher average harvested energy compared with the conventional cooperative technique.
