Current Projects

Real-time disaster detection and management system based on social media over clouding computing environment

Autonomic Computing environments (Autonomia) : Provides the application developers with all the tools required to specify the appropriate control and management schemes to maintain any quality of service requirement or application attribute/functionality (e.g., performance, fault, security, etc.) and the core autonomic middleware services to maintain the autonomic requirements of a wide range of network applications and services.
Workflow based Grid-Computing for Problem Solving Environments : Developing a grid portal that provides runtime environments and task developing tools for large and complex computational science problems.
Self-Healing Networks : Develop network management system which can detect some possible failures in a network system, and recover from failures to avoid catastrophic disasters such as being down entire network.
Proactive runtime communication management agent (PROMA): PROMA is capable of proactively and adaptively configuring, and managing applications' communication environments by a predictive communication environment model that represents the communication requirements of applications and current network status.
 

Past Projects

CSC3453 Web-based Hospital Computerized Disaster Information and Management System (CDIMS): develop a novel web service based Computerized Disaster Information and Management System (CDIMS) to direct disaster management by hospitals. CDIMS will assist with disaster preparation as well as command and communications during a disaster. This project is funded by NIH (with Drs. Little and Ward-Gaines, Grant number: 1G08LM009710-01, May 2008-May 2011)
CSC3453 Development of Parallel Computing Environment of Huge Data Processing : Developing parallel data link level simulator. Funded by Electronics and Telecommunications Research Institute (ETRI) , Dajeon, South Korea.
CSC3453 Adaptive Computing Environments for high-performance distributed applications over Grid (ADViCE): A web-based parallel and distributed computing environment that allows users to develop large scale parallel and distributed applications using libraries of parallel/distributed function modules and run them across the networks over Grid Computing Environment.
CSC3453 Peer-to-Peer distributed storage system : Developing an intelligent P2P file storage system which allows users to store and retrieve their data at any nodes which may be very secure nodes or un-secure nodes without worry about the security and reliability of their stored data.
CSC3453 Peer-to-Peer messaging system : Developing an JXTA based message passing system for P2P applications.
CSC3453
Adaptive Communication Systems (ACS) : ACS is an adaptive high performance message-passing system that provides programmable communication, control and management services to meet the Quality of Service (QoS) requirements of applications. In addition, developed analytical performance models for adaptive group communication services that are aware of network and computing resources and application requirements.
