Introduction
Jeongho Kwak received the Bachelor degree (Summa cum laude) in electrical engineering from Ajou University, Korea in Aug. 2008. He received the Master degree and Ph.D. degree in electrical engineering from KAIST, Korea, in Feb. 2011 and Feb. 2015, respectively under supervision of Prof. Song Chong. He was a postdoctoral researcher at INRS and Western University in Canada. Currently, he is a Marie-Curie Research Fellow at Trinity College Dublin, Ireland. His current research interests lie on storage/computing/networking resource orchestration in hierarchical edge computing architecture.

Article
Massive Multi-Input Multi-Output (MIMO) and Coordinated MultiPoint (CoMP) technologies in Cloud-RAN (C-RAN) architecture become inevitable trend due to the advent of next-generation mobile applications, which are traffic-intensive, such as ultra high definition (UHD) video. In this paper, we study a joint beam activation and user scheduling problem...
Article
Computational resources are increasingly virtualized to enable computational tasks to be offloaded to remote facilities along the route between the source and destination. The principle that underlies traditional routing, i.e., that only networking resources need to be considered, may no longer be true in a virtualized environment. In this paper, w...
Article
The advent of elastic Content Delivery Networks (CDNs) enable Content Providers (CPs) to lease cache capacity on demand and at different cloud and edge locations in order to enhance the quality of their services. This article addresses key challenges in this context, namely how to invest an available budget in cache space in order to match spatio-t...
Conference Paper
We begin this paper by asking a simple question: All beams can be simultaneously activated thanks to the ignorable inter-beam interference and sharp beam shape in mmWave networks? This paper provides a counter-intuitive observation that interference between one-hop adjacent beams still significantly affects the network performance in mmWave network...
Article
More network operators have recently provided CDN (Content Delivery Network) services where traffic engineering techniques such as the BS association are jointly employed with content delivery. This deployment attempts to reduce the network operating cost and enhance the QoS (Quality of Service) of end users. Toward this end, we study the base stat...
Article
In this letter, we propose a virtual beamforming and user scheduling technique, namely VirtualBus which attains higher beamforming gain by generating narrower beams in a sub-array mmWave network architecture. These narrower beams are generated by making adjacent subsets of antenna elements connected to individual RF chains into a logical subset of...
Article
A fundamental question in the study of location-based mobile sensing is how much energy can be saved while still guaranteeing reliable localization accuracy. In this paper, we analyze key features of mobile devices, and obtain a motivation that we can efficiently and accurately acquire locations by sharing the locations among nearby mobile devices....
Article
Most existing content caching designs require accurate estimation of content popularity, which can be challenging in the dynamic mobile network environment. Moreover, emerging hierarchical network architecture enables us to enhance the content caching performance by opportunistically exploiting both cloud-centric and edge-centric caching. In this p...
Article
We study the secondary user power allocation problem in cognitive radio networks with uncertain knowledge of interference information. We capture the channel uncertainty in the chance-constrained formulation where interference to primary users is guaranteed to be below a given threshold with high probability. However, the formulation is nonconvex,...
Article
Recently, as plug-in hybrid electric vehicles (PHEVs) take center stage for the eco-friendly and cost-effective transportation, commercial PHEV charging stations will be widely prevalent in the future. However, previous studies in the fields of the management of PHEV charging stations have not synthetically taken practical charging systems into acc...

Mobile cloud computing (MCC) has been proposed to offload heavy computing jobs of mobile devices to cloud servers managed by cloud service provider (CSP), which enables the mobile devices to save energy and processing delay. Heretofore, cloud offloading policies in mobile devices and pricing/scheduling in CSP have been independently addressed. This...
Conference Paper
Energy-delay tradeoffs in smartphone applications have been studied independently in dynamic voltage and frequency scaling (DVFS) problem and network interface selection problem. We optimize the two problems jointly to quantify how much energy can be saved further and propose a scheme called SpeedControl which jointly manages application scheduling...

Small cells such as pico or femto cells are promising as a solution to cope with higher traffic explosion and the large number of users. However, the users within small cells are likely to suffer severe inter-cell interference (ICI) from neighboring base stations (BSs). To tackle this, several papers suggest BS transmit power on/off control algorit...
Conference Paper
The key issue of the localization study is that how we can minimize the energy consumption of devices with guaranteeing high degree of accuracy. In this paper, we show that the collaboration among proxy devices with short range communication is helpful to energy-efficiently localize their locations in time-average sense by analyzing the device prox...
Article
Greening effect in interference management (IM), a way of enhancing spectrum sharing via intelligent transmit power control, can be achieved by the fact that as BSs moderately reduce their transmit powers, the performance degradation decreases slower than linearly, yet a considerable overall energy saving is expected due to transmit powers' exertin...
Conference Paper
Greening effect in interference management (IM), which is a technology to enhance spectrum sharing via intelligent BS transmit power control, can be achieved by the fact that even small reduction in BS transmit powers enables considerable saving in overall energy consumption due to their exerting influence on operational powers. In this paper, we s...
