A Deep Learning-Based Weather Forecast System for Data Volume and Recency Analysis

February 18, 2019
Author(s)
Jarrett Booz, Wei Yu, Guobin Xu, David W. Griffith, Nada T. Golmie
Accurate weather forecast is important to our daily life. Through physical atmospheric models, the weather can be accurately forecasted in a short period time. To provide weather forecast, machines learning techniques can be used for understanding and

Performance Assessment of Smart Meter Traffic over LTE Network Using SDR Testbed

February 18, 2019
Author(s)
Amirshahram Hematian, Wei Yu, David W. Griffith, Nada T. Golmie
In the smart grid, a variety of smart meters will be deployed to support diverse services, such as energy distribution management, grid monitoring and management, and the integration of renewable energy resources. On the power distribution side, regular

A User Application-Based Access Point Selection Algorithm for Dense WLANs

January 16, 2019
Author(s)
Munsuk Kim, Ye Na Kim, Sukyoung Lee, Nada T. Golmie, SeungSeob Lee
The current commercial access point (AP) selection schemes are mostly based on signal strength, but perform poorly in many situations because they ignore the actual load distributions among the APs. To address this shortcoming, a number of alternative

Efficient MU-MIMO Beamforming Protocol for IEEE 802.11ay WLANs

January 1, 2019
Author(s)
Munsuk Kim, Tanguy Ropitault, SuKyoung Lee, Nada T. Golmie
IEEE 802.11ay supports multi-user multiple-input-multiple-output (MU-MIMO). However, the MU- MIMO BFT (Beamforming Training) is a time-consuming process to find appropriate directional antenna patterns, and inefficient BFT results in a long training time

Millimeter-Wave Channel Measurement and Modeling: A NIST Perspective

December 7, 2018
Author(s)
Camillo A. Gentile, Peter B. Papazian, Nada T. Golmie, Catherine A. Remley, Peter G. Vouras, Jelena Senic, Jian Wang, Jack Chuang, Ruoyu Sun
The exponential increase in wireless data transmission from smartphones has led to the saturation of the sub-6-GHz bands, forcing cellular providers to migrate to the millimeter-wave (mmWave) regime for 5G. Although available channel bandwidths will grow

Millimeter-Wave Propagation Channels vs. Synthetic Beamwidth

December 7, 2018
Author(s)
Roy Sun, Camillo A. Gentile, Jelena Senic, Peter G. Vouras, Peter B. Papazian, Nada T. Golmie, Catherine A. Remley
High-gain narrow-beam antennas or beamformed antenna arrays will likely be used in millimeter- wave (mmWave) bands and 5G to mitigate the high path loss. Since many multipath components may be excluded by the narrow beam, the mmWave propagation channels

A Survey on Industrial Internet of Things: A Cyber-Physical Systems Perspective

December 4, 2018
Author(s)
Hansong Xu, Wei Yu, David W. Griffith, Nada T. Golmie
The vision of Industry 4.0, otherwise known as the fourth industrial revolution, is the integration of massively deployed smart computing and network technologies in industrial production and manufacturing settings for the express purposes of automation

A 3D Topology Optimization Scheme for M2M Communications

June 29, 2018
Author(s)
Yalong Wu, Wei Yu, Jin Zhang, David W. Griffith, Nada T. Golmie
Without efficient topology management, M2M communications will likely asymmetrically congest gateways and eNodeBs in 3rd Generation Partnership Project (3GPP) Long-Term Evolution (LTE) and Long-Term Evolution Advanced (LTE-A) networks, especially when M2M

A Dynamic Rate Adaptation Scheme for M2M Communications

May 24, 2018
Author(s)
Yalong Wu, Wei Yu, David W. Griffith, Nada T. Golmie
The number of Machine-to-Machine (M2M) devices has continued to grow at an accelerated rate. Without thoughtful and efficient resource management, M2M communications will be asymmetrically handicapped by service rate scarcity as more devices are

A Framework to Enable Multiple Coexisting Internet of Things Applications

March 1, 2018
Author(s)
Wei Yu, Hanlin Zhang, Yalong Wu, David W. Griffith, Nada T. Golmie
Internet of Things (IoT) uses modern information communication technologies to connect massive numbers of objects and support numerous smart critical infrastructure applications (smart grid, smart cites, etc.). To meet the diverse performance requirements

Performance Evaluation of Energy Efficiency with Sleep Mode in Ultra Dense Networks

March 1, 2018
Author(s)
Hansong Xu, Wei Yu, Amirshahram Hematian, David W. Griffith, Nada T. Golmie
Massively deployed mobile devices and an extensive volume of data traffic will immensely increase demand on future wireless networks. The Ultra Dense Network (UDN), as one of key techniques in 5G, is expected to support massive connections and offload the
