Project Description

Mobile cloud computing is the usage of cloud computing in combination with mobile devices to access data and perform tasks on demand from the Internet. The technology has enabled numerous novel applications, but it has also escalated the problem of network traffic overload and energy consumption. One limitation of mobile cloud computing is that the mobile devices have limited battery lifetime. In this project, we will tackle an important challenge of designing and developing a green mobile cloud platform that can support energy-efficient content distribution and offloading services. Our goal is to reduce energy consumption of mobile devices and improve quality of experiences of users. We will investigate how to provide energy-efficient content placement and information retrieval in mobile cloud computing. We will also explore how to optimize the energy consumption and data delay by intelligently offloading computation, communication and storage to the cloud.
