KUMAR, SUJAY, VIJAYA. Vitri A Generic Framework for Engineering Decision Support Systems on Heterogeneous Computer Networks. (Under the direction of Dr. John W. Baugh) Vitri is an object-oriented framework implemented in Java for high-performance distributed computing. Using Vitri, applications can engage in cooperative problem solving by dividing their tasks among heterogeneous clusters of wor...

In cloud computing, a cloud is a managed pool of resources which provide on-demand services or computational resources to the remote users over a network. The resources are provided to users in the form of virtual machines and are possibly distributed and heterogeneous, running on the cloud environment over Internet. Energyaware Scheduling algorithm and Energy-aware Live Migration algorithm red...

New techniques, languages and paradigms have facilitated the creation of distributed applications in several areas. Perhaps the most promising paradigm is the one that incorporates the mobile agent concept. A mobile agent in a largescale network can be viewed as a software program that travels through a heterogeneous network, crossing various security domains and executing autonomously in its d...

Heterogeneous wireless networks are capable of providing customers with better services while service providers can offer more applications to more customers with lower costs. Many services require the support of location management functions, which still need further innovations to become viable in multi-hop vehicular ad-hoc networks (VANETs). High mobility in vehicular networks causes convent...

The decision of which servers to dispatch to which customers is an important aspect of serverto-customer systems. Such decisions are complicated when servers have different operating characteristics, customers are prioritized, and there are errors in assessing customer priorities. In this paper, we formulate a model for determining how to optimally dispatch distinguishable servers to prioritize...

As the Web evolves from providing information access into a platform for e-business, there is a need for technologies to support dynamic inter-enterprise collaboration. Toward this goal, we have developed Internet Business Servers (IBSs). This approach essentially turns individual Web servers into communicating and collaborating servers, with extended functionality for inter-enterprise business...

This paper provides an analytical solution for the time-dependent performance evaluation of truck handling operations at an air cargo terminal. The demand for loading and unloading operations is highly time-dependent and stochastic for two classes of trucks. Two heterogeneous handling facilities with multiple servers are available to handle trucks assuming exponentially distributed processing t...

We consider the problem of controlling a two-server Markovian queueing system with heterogeneous servers. The servers are differentiated by their service rates and reliability attributes (i.e., the slower server is perfectly reliable while the faster server is subject to random failures). The aim is to dynamically route customers at arrival, service completion, server failure, and server repair...

We consider a non-standard class of Markovian time: varying infinite capacity queues with possibly heterogeneous servers and impatience. assume that during service time, customer may switch to the faster server (with no delay), when such becomes available other customers are waiting. As result, in queue become impatient leave it. Under this setting certain restrictions on intensity functions, q...

This paper presents a tool for dynamic forecasting of Network-Enabled Servers performance. FAST (Fast Agent’s System Timer) is a software package allowing client applications to get an accurate forecast of communication and computation times and memory use in a heterogeneous environment. It relies on low level software packages, i.e., network and host monitoring tools, and some of our developme...
