Energy Efficiency Analysis in Cache-Enabled D2D-Aided Heterogeneous Cellular Networks
IEEE Access, 2020 Small cells (SCs) offer a promising approach to meeting the exponentially growing data rate demands. However, dense deployment of SCs can degrade the energy-efficiency (EE) of the network due to the additional deployed base stations (BSs).

Spatial spectrum and energy efficiency of random cellular networks [PDF]
, 2015 It is a great challenge to evaluate the network performance of cellular mobile communication systems. In this paper, we propose new spatial spectrum and energy efficiency models for Poisson-Voronoi tessellation (PVT) random cellular networks. To evaluate

Equivalence and comparison of heterogeneous cellular networks [PDF]
2013 IEEE 24th International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC Workshops), 2013 We consider a general heterogeneous network in which, besides general propagation effects (shadowing and/or fading), individual base stations can have different emitting powers and be subject to different parameters of Hata-like path-loss models (path-loss exponent and constant) due to, for example, varying antenna heights.

The impact of user spatial heterogeneity in heterogeneous cellular networks [PDF]
2014 IEEE Globecom Workshops (GC Wkshps), 2014 The spatial distribution of users in cellular networks plays an important role on network performance. It is becoming increasingly common in the recent literature to model the user locations according to a homogeneous Poisson point process, yet users are often spatially clustered in reality.

Downlink outage performance of heterogeneous cellular networks [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 This paper derives tight performance upper and lower bounds on the downlink outage efficiency of K-tier heterogeneous cellular networks (HCNs) for general signal propagation models with Poisson distributed base stations in each tier. In particular, the proposed approach to analyze the outage metrics in a K-tier HCN allows for the use of general bounded
