Enabling smart spaces with OSGi
Choonhwa Lee, David Nordstedt, Sumi Helal
SJR Q3IEEE Pervasive Computing

Today's pervasive computing spaces are developed primarily with proprietary technology and seem to lack a long-term vision of evolution and interoperation. The future pervasive computing environment will comprise a wide variety of devices and services from different manufacturers and developers. We must therefore achieve platform and vendor independence as well as architecture openness before pervasive computing spaces become common places. The Open Services Gateway Initiative attempts to meet t

Context attributes: an approach to enable context-awareness for service discovery
Choonhwa Lee, Sumi Helal

The service discovery problem has attracted a lot of attention from researchers and practitioners. Jini, SLP, and UPnP are among the few emerging service discovery protocols. Although they seem to provide a good solution to the problem, there is an unaddressed need of more sophisticated location and context-aware service selection support. In this paper, we introduce the concept of context attribute as an effective, flexible means to exploit relevant context information during the service discov

Konark: a system and protocols for device independent, peer-to-peer discovery and delivery of mobile services
Choonhwa Lee, Sumi Helal, Nirmit Desai, Vikas Verma, Burak Arslan
IEEE Transactions on Systems Man and Cybernetics - Part A Systems and Humans

The proliferation of mobile devices and the pervasiveness of wireless technology have provided a major impetus to replicate the network-based service discovery technologies in wireless and mobile networks. However, existing service discovery protocols and delivery mechanisms designed for traditional infrastructure-based networks fall short of accommodating the complexities of the ad hoc environment. Konark is a service discovery and delivery protocol designed specifically for ad hoc, peer-to-pee

TOSCA-Based and Federation-Aware Cloud Orchestration for Kubernetes Container Platform
Dongmin Kim, Muhammad Hanif, Eunsam Kim, Sumi Helal, Choonhwa Lee
SJR Q2Applied SciencesOA

Kubernetes, a container orchestration tool for automatically installing and managing Docker containers, has recently begun to support a federation function of multiple Docker container clusters. This technology, called Kubernetes Federation, allows developers to increase the responsiveness and reliability of their applications by distributing and federating container clusters to multiple service areas of cloud service providers. However, it is still a daunting task to manually manage federated c

Universal Interactions with Smart Spaces
Choonhwa Lee, Sumi Helal, Wonjun Lee
SJR Q3IEEE Pervasive Computing

A critical challenge facing the pervasive computing research community is the need to manage complex interactions among numerous interconnected computers and devices. In such a pervasive space, a given application's functionalities are partitioned and distributed across several computing devices that are spontaneously discovered and used. In recent years, researchers have devoted much attention to universal interactions with diverse devices in richly networked settings. We can categorize the num

A scalable blockchain-enabled federated learning architecture for edge computing
Shuyang Ren, Eunsam Kim, Choonhwa Lee
SJR Q1PLoS ONEOA

Various deep learning techniques, including blockchain-based approaches, have been explored to unlock the potential of edge data processing and resultant intelligence. However, existing studies often overlook the resource requirements of blockchain consensus processing in typical Internet of Things (IoT) edge network settings. This paper presents our FLCoin approach. Specifically, we propose a novel committee-based method for consensus processing in which committee members are elected via the FL

A popularity-aware prefetching scheme to support interactive P2P streaming
Choonhwa Lee, Euiyoung Hwang, Dohoo Pyeon
SJR Q1IEEE Transactions on Consumer Electronics

Improved interactive functionality is considered the next crucial milestone for a wider acceptance, when it comes to P2P-based streaming service over the Internet. As the streaming systems evolve, users expect to have full control over what they view and how they view it. This paper presents a viable solution to support user interactivity for P2P VoD streaming service. Our proposal of popularity-aware chunk prefetching protocol is capable of tracking chunk popularities over a video, based on whi

VM Capacity-Aware Scheduling within Budget Constraints in IaaS Clouds
Vasileios Thanasias, Choonhwa Lee, Muhammad Hanif, Eunsam Kim, Sumi Helal
SJR Q1PLoS ONEOA

Recently, cloud computing has drawn significant attention from both industry and academia, bringing unprecedented changes to computing and information technology. The infrastructure-as-a-Service (IaaS) model offers new abilities such as the elastic provisioning and relinquishing of computing resources in response to workload fluctuations. However, because the demand for resources dynamically changes over time, the provisioning of resources in a way that a given budget is efficiently utilized whi

A Machine Learning-Based Anomaly Prediction Service for Software-Defined Networks
Zohaib Latif, Qasim Umer, Choonhwa Lee, Kashif Sharif, Fan Li, Sujit Biswas
SJR Q1SensorsOA

Software-defined networking (SDN) has gained tremendous growth and can be exploited in different network scenarios, from data centers to wide-area 5G networks. It shifts control logic from the devices to a centralized entity (programmable controller) for efficient traffic monitoring and flow management. A software-based controller enforces rules and policies on the requests sent by forwarding elements; however, it cannot detect anomalous patterns in the network traffic. Due to this, the controll

An efficient service propagation scheme for large-scale MANETs
Choonhwa Lee, Sungshick Yoon, Eunsam Kim, Sumi Helal

This paper proposes a new scheme for efficient dissemination and discovery of service information in mobile ad hoc networks. By extending Bloom filter-based service summarization scheme, our discovery middleware layer also encodes distance to services in summarization filters. By having the distance information gradually attenuated during its propagation, our proposal enables faster discovery of services with a limited amount of advertisement traffic.

SJR Q1PLoS ONEOA

The orchestration of applications and their components over heterogeneous clouds is recognized as being critical in solving the problem of vendor lock-in with regards to distributed and cloud computing. There have been recent strides made in the area of cloud application orchestration with emergence of the TOSCA standard being a definitive one. Although orchestration by itself provides a considerable amount of benefit to consumers of cloud computing services, it remains impractical without a com
