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

Modeling and Simulation Analysis of the Physical Sidelink Shared Channel (PSSCH)

May 24, 2018
Author(s)
David W. Griffith, Fernando J. Cintron, Timothy Hall, Richard A. Rouil
This paper examines the performance of the Long Term Evolution (LTE) Physical Sidelink Shared Channel (PSSCH) in out-of-coverage (OOC) device-to-device (D2D) communication scenarios. We develop a closed form expression for the distribution of the number of

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

Enhanced Transmission Algorithm for Dynamic Device-to-Device Direct Discovery

January 12, 2018
Author(s)
Aziza Ben Mosbah, David W. Griffith, Richard A. Rouil
In order to support the increasing demand for capacity in cellular networks, Long Term Evolution (LTE) introduced Proximity Services (ProSe) enabling Device-to-Device (D2D) communications, defining several services to support such networks. We are

Adaptive synchronization reference selection for out-of-coverage Proximity Services (ProSe)

October 8, 2017
Author(s)
Samantha M. Gamboa Quintiliani, Fernando J. Cintron, David W. Griffith, Richard A. Rouil
Proximity services (ProSe) is a Long Term Evolution Advanced (LTE-A) feature that allows User Equipments (UEs) to communicate without the need of routing the data throughout the network. In this paper, we studied the synchronization protocol used by ProSe

Towards Detecting Data Integrity Attacks in Smart Grid

October 6, 2017
Author(s)
Linqiang Ge, Wei Yu, Paul Moulema, Guobin Xu, David W. Griffith, Nada T. Golmie
An effective operation of the smart grid relies on the integration of sensing, computing, and communication. Attempting to disrupt the system, an adversary may launch cyber-attacks against the smart grid by compromising components, including meters

A Novel Adaptive Transmission Algorithm for Device-to-Device Direct Discovery

June 27, 2017
Author(s)
Aziza Ben Mosbah, David W. Griffith, Richard A. Rouil
In this paper we study and improve one service used for Proximity Services and Device-to-Device (D2D) communications: D2D Direct Discovery. As defined in the Third Generation Partnership Project, for both in-coverage and out-of-coverage cases, resource

Physical Sidelink Control Channel (PSCCH) in Mode 2: Performance Analysis

May 25, 2017
Author(s)
David W. Griffith, Fernando J. Cintron, Richard A. Rouil
User Equipments (UEs) that send data must advertise the upcoming transmission by broadcasting signaling messages over the Physical Sidelink Control Channel (PSCCH). Thus, it is important for the network operator to define the PSCCH resource pool to

Group Discovery Time in Device-to-Device (D2D) Proximity Services (ProSe) Networks

May 4, 2017
Author(s)
David W. Griffith, Aziza Ben Mosbah, Richard A. Rouil
Device-to-device (D2D) communications for Long Term Evolution (LTE) networks relies on a discovery process to enable User Equipment (UE) to determine which D2D applications and services are supported by neighboring UEs. This is especially important for

AP Selection Algorithm with Adaptive CCAT for Dense Wireless Networks

March 22, 2017
Author(s)
Ye Na Kim, Munsuk Kim, SuKyoung Lee, David W. Griffith, Nada T. Golmie
Wireless Local Area Networks (WLANs)-enabled devices are now everywhere and their rapid spread has created dense deployment environments. For such dense WLANs, the High Efficiency WLAN Study Group was formed, and as an extension of their activity, effort
