This paper presents a systematic approach for implementing a class of nonlinear signal processing systems as a distributed web service, which in turn is used to solve optimization problems in a distributed, asynchronous fashion. As opposed to requiring a specialized server, the presented approach requires only the use of a commodity database back-end as a central resource, as might typically be...

Modern web-based application infrastructures are based on clustered, multi-tiered architectures, where request distribution occurs in two sequential stages: over a cluster of web servers, and over a cluster of application servers. Much work has focused on strategies for distributing requests across a web server cluster in order to improve overall throughput across the cluster. The strategies ap...

service level agreement, web performance tuning, software performance modeling, response time, queueing, optimization We present a nonlinear integer optimization model for determining the number of machines at each tier in a multi-tier server network. We utilize a result from an open queueing network model on the average response time; the optimization model is to minimize a weighted sum of tot...

Now a days, the cloud platform plays a very important roles in development environment to implement various applications over servers. The developer should to know the latency to select appropriate server which in turn takes less time and perform the task very quickly. The main objective of this paper is to help the developers to check the latency of Amazon web services (AWS). By knowing the la...

Dynamic Web content is increasing in popularity and, by its nature, is harder to scale than static content. As a result, dynamic Web content delivery degrades more rapidly than static content under similar client request rates. Many techniques have been explored for effectively handling heavy Web request traffic. In this paper, we concentrate on dynamic content degradation, believing that it of...

Cloud computing is the latest evolution of computing where the IT resources are offered as services following the “pay-per-usage” pricing model. Cloud’s scalability feature causes variable price for resources governed by the cloud service providers. Therefore, the cloud customers’ main interest is whether the performance scales to the price for the leased resources in the cloud. In this paper w...

PERFORMANCE ANALYSIS OF ALGORITHMS FOR SUPPORTING DISCONNECTED WRITE OPERATIONS IN WIRELESS WEB ENVIRONMENTS Ngoc Anh Phan M.S. thesis directed by Dr. Ing-Ray Chen A mobile user may voluntarily disconnect itself from the web server to save battery life and also to avoid the high communication price. To allow web pages to be updated while the mobile user is disconnected from the web server, upda...

Mobile cloud computing (MCC) is a new technology that has been developed to overcome the restrictions of smart mobile devices (e.g. battery, processing power, storage capacity, etc.) to send a part of the program (with complex computing) to the cloud server (CS). In this paper, we study a multi-cell with multi-input and multi-output (MIMO) system in which the cell-interior users request service...
