Toward Integrating Distributed Energy Resources and Storage Devices in the Smart Grid

February 1, 2017
Author(s)
Guobin Xu, Wei Yu, David W. Griffith, Nada T. Golmie, Paul Moulema
The smart grid, as one of typical applications supported by Internet of Things, denoted as a re-engineering and a modernization of the traditional power grid, aims to provide reliable, secure, and efficient energy transmission and distribution to consumers

Impact of timing on the Proximity Services (ProSe) synchronization function

January 8, 2017
Author(s)
Samantha Gamboa Quintiliani, Fernando Cintron, David W. Griffith, Richard A. Rouil
Long Term Evolution Advanced (LTE-A) introduces a new feature called Proximity Services (ProSe), which enables device-to-device (D2D) communication between User Equipment (UE) and the capability to operate out-of-network. In order to establish a D2D

Towards Energy Efficiency in Ultra Dense Networks

December 11, 2016
Author(s)
Wei Yu, Hansong Xu, Amirshahram Hematian, David W. Griffith, Nada T. Golmie
The Ultra Dense Network (UDN), as a key enabler for future wireless networks (such as 5G), is comprised of a massive number of small cells in the network. Nonetheless, energy consumption will be non-negligible when a large number of small- cell Base

Optimizing the UE Transmission Probability for D2D Direct Discovery

December 5, 2016
Author(s)
David W. Griffith, Fiona Z. Lyons
We develop an analytical model to examine the effect of the transmission probability on type~1 direct discovery in Device-to-Device (D2D) Long Term Evolution (LTE) networks. The model gives us the distribution of the time for a User Equipment (UE) to

A Clustering-Based Device-to-Device Communication to Support Diverse Applications

October 13, 2016
Author(s)
Amirshahram Hematian, Wei Yu, Chao Lu, David W. Griffith, Nada T. Golmie
The expanding coverage and capacity of cellular networks through broadband wireless infrastructure has limitations in accommodating the expanding strain and capacity required by diverse applications (public safety, smart grid, transportation, healthcare

Ultra-Dense Networks: Survey of State of the Art and Future Directions

August 4, 2016
Author(s)
Wei Yu, Hansong Xu, Hanlin Zhang, David W. Griffith, Nada T. Golmie
Abstract—Within the foreseeable future, the growing number of mobile devices, and their diversity, will challenge the current network architecture. Furthermore, users expect higher data rates, lower latency, lower packet drop rates, etc. in future wireless

On Effectiveness of Smart Grid Applications using Co-simulation

August 6, 2015
Author(s)
Paul Moulema, Wei Yu, David W. Griffith, Nada T. Golmie
The smart grid is a complex system that comprises components from both the power grid and communication networks. To understand the behavior of such a complex system, co-simulation is a viable tool to capture the interaction and the reciprocal effects

Nationwide Public Safety Broadband Network Deployment: Network Parameter Sensitivity Analysis

March 15, 2015
Author(s)
Richard A. Rouil, Antonio Izquierdo Manzanares, Camillo A. Gentile, David W. Griffith, Nada T. Golmie
The legislation included in the middle class tax relief and job creation act of 2012 established the First Responder Network Authority (FirstNet) for the purpose of deploying and running a nationwide Long Term Evolution (LTE) network for Public Safety

Measuring the Resiliency of Cellular Base Station Deployments

March 11, 2015
Author(s)
David W. Griffith, Richard A. Rouil, Antonio Izquierdo Manzanares, Nada T. Golmie
The National Public Safety Telecommunications Council (NPSTC) has defined Resiliency as the ability of a network to withstand the loss of assets and to recover quickly from such losses. How to measure the resiliency of a base station deployment is an

Optimizing the Location Deployment of Dynamic Mobile Base Stations

February 19, 2015
Author(s)
Sulabh Bhattarai, Sixiao Wei, Stephen Rook, Wei Yu, David W. Griffith, Nada T. Golmie
There has been growing interest over the past few years in the US and around the world to build reliable, robust, and interoperable public safety broadband networks for emergency and disaster response. In this paper, we propose a low-cost, dynamic

Optimal Deployment of Pico Base Stations in LTE-Advanced Heterogeneous Networks

October 29, 2014
Author(s)
Sungseob Lee, SuKyoung Lee, Kim KyungSoo, David W. Griffith, Nada T. Golmie
As data traffic demand in cellular networks grows exponentially, operators need to add new cell sites to keep up; unfortunately, it is costly to build and operate macrocells. Moreover, it may not be possible to obtain the needed approvals for additional

On Cascading Failures and Countermeasure based on Energy Storage in the Smart Grid

October 8, 2014
Author(s)
Xing Chen, Wei Yu, David W. Griffith, Nada T. Golmie, Guobin Xu, Chao Lu
Recently, there are growing concerns about smart grid security and resilience. The performance of smart grid may suffer from component failures or targeted attacks. A sophisticated adversary may target critical components in a smart grid, leading to
