Energy Efficient Pico Cell Range Expansion and Density Joint Optimization for Heterogeneous Networks with eICIC

open access: yesSensors, 2018
Heterogeneous networks, constituted by conventional macro cells and overlaying pico cells, have been deemed a promising paradigm to support the deluge of data traffic with higher spectral efficiency and Energy Efficiency (EE).

A spatial slotted-Aloha protocol in wireless networks for group communications

open access: yesEURASIP Journal on Wireless Communications and Networking, 2017
In a large-scale group communication networks, we propose a slotted-Aloha-based access control (SA-AC) scheme with the optimal transmission probability (TP) using the stochastic geometry.

The Geometry of Crashes - A Measure of the Dynamics of Stock Market Crises [PDF]

open access: yes
This paper investigates the dynamics of stocks in the S&P500 index for the last 30 years. Using a stochastic geometry technique, we investigate the evolution of the market space and define a new measure for that purpose, which is a robust index of the ...

Research on GPS geometry-based observational stochastic error model

open access: yesTongxin xuebao, 2019
Aiming at the problem of not enough influencing factors were considered in traditional methods,a much more realistic stochastic model was built.In which error corrections were introduced into the geometry-based function model,an improved least squares ...

How Nonassociative Geometry Describes a Discrete Spacetime

open access: yesFrontiers in Physics, 2019
Nonassociative geometry, providing a unified description of discrete and continuum spaces, is a valuable candidate for the study of discrete models of spacetime. Within the framework of nonassociative geometry we propose a model of emergent spacetime. In
