Analysis of coverage probability in NOMA-HetNet based on Matern cluster process [PDF]

open access: yesTongxin xuebao, 2020
Considering the correlation between the users and base stations and the network irregularity,the non-orthogonal multiple access heterogeneous networks (NOMA-HetNet) based on Matern cluster process (MCP) was modeled.The coverage probability of UEs was ...

Modelling and analysis of heterogeneous cellular networks using a matern cluster process [PDF]

open access: yesIET Communications, 2017
Heterogeneous cellular networks (HCNs) are usually modelled as a Poisson point process (PPP) due to mathematical tractability. However, in urban areas, small cells are more likely to cluster around hotspots rather than be uniformly distributed. Meanwhile, in reality, small cell locations are not completely independent of the macro base station (MBS ...

User Association for Offloading in Heterogeneous Network Based on Matern Cluster Process [PDF]

open access: yes2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017
Future mobile networks are converging toward heterogeneous multi-tier networks, where various classes of base stations (BS) are deployed based on user demand. So it is quite necessary to utilize the BSs resources rationally when BSs are sufficient. In this paper, we develop a more realistic model that fully considering the inter-tier dependence and the

Distance distributions for Matérn cluster processes with application to network performance analysis [PDF]

open access: yes2017 IEEE International Conference on Communications (ICC), 2017
In this work, we analyze the distance statistics corresponding to points in a Matern cluster (offspring points) and points that do not belong to that cluster (non-offspring points). We first derive the probability density function (PDF) of the distance between an offspring point and a non-offspring point of a Matern cluster.

On the Contact and Nearest-Neighbor Distance Distributions for the ${n}$ -Dimensional Matérn Cluster Process [PDF]

open access: yesIEEE Wireless Communications Letters, 2020
This letter provides exact characterization of the contact and nearest-neighbor distance distributions for the n dimensional (n-D) Matern cluster process (MCP). We also provide novel upper and lower bounds to these distributions in order to gain useful insights about their behavior.

The implementation and effectiveness of multi-tasked, paid community health workers on maternal and child health: A cluster-randomized pragmatic trial and qualitative process evaluation in Tanzania

open access: yesPLOS Global Public Health, 2023
Abstract Community health worker programs have proliferated worldwide based on evidence that they help prevent mortality, particularly among children. However, there is limited evidence from randomized studies on the processes and effectiveness of implementing community health worker programs through public health ...
