Cloudlet Vision: Examined Cloudlets Performance while End-Users use Multimedia Contents

摘要

Objective: Mobile devices have been found to perform high-performance processing tasks, as smart phones are increasingly becoming popular accompanied by development of mobile applications. Battery life, memory, weight, and heat dissipation limit the computational resources of the device. Cloud computing can be one of the best solutions to overcome mobile devices limitations. However, some of the problems that can be experienced in cloud computing include costly roaming charges and long-latency of cellular radio access. The purpose of this research paper is to develop an approach, which uses coordination between cloudlets, to not only enhance the performance of cloud access, but also bring new experience among mobile device users. Methods: A research review methodology was adopted to undertake analysis of the existing experimental studies on cloudlet computing to understand their proposed models, protocols, and theoretical framework for enhancing access and security of data from remote cloud using mobile devices, where cloudlets serve as intermediary. Location-Aware Service Deployment (LASD) algorithm was proposed to enhance cloudlet coordination through reduction of latency. Findings: The findings of existing experimental studies reveal several conclusive observations. There are benefits provided by the use of cloudlets over the remote cloud. They include faster processing of an application, faster data transfer as well as reducing the use of mobile resources. In the study, we have examined the data latency in the process of connections and data transfer between cloudlets including the distance cloud servers with and without coordination, using multimedia files. Application: Coordinated cloudlets will help clients to have their multimedia files to be transferred faster within the environment of cloud-computing.
