In this paper, we study drone small cells (DSCs) network modeled by 3D Poisson point process. We further study an underlay spectrum sharing between the 3D DSCs network and traditional cellular networks modeled by 2D Poisson Point Processes. We derive the explicit expressions for the downlink DSCs coverage probability and achievable throughput.We obtain the optimal density of DSCs aerial base stations...
The emerging 5G wireless networks will pose extreme requirements such as high throughput and low latency. Caching as a promising technology can effectively decrease latency and provide customized services based on group users behaviour (GUB). In this paper, we carry out the energy efficiency analysis in the cache-enabled hyper cellular networks (HCNs), where the macro cells and small cells (SCs) are...
Network densification has always been an important factor to cope with the ever increasing capacity demand. Deploying more base stations (BSs) improves the spatial frequency utilization, which increases the network capacity. However, such improvement comes at the expense of shrinking the BSs' footprints, which increases the handover (HO) rate and may diminish the foreseen capacity gains. In this paper,...
