A Survey of Mobile Cloud Computing

Mobile Cloud Computing (MCC) is emerging as one of the most important branches of cloud computing. In this paper, MCC is defined as cloud computing extended by mobility, and a new ad-hoc infrastructure based on mobile devices. It provides mobile users with data storage and processing services on a cloud computing platform. Because mobile cloud computing is still in its infancy, we aim to clarify confusion that has arisen from different views. Existing works are reviewed, and an overview of recent advances in mobile cloud computing is provided. We investigate representative infrastructures of mobile cloud computing and analyze key components. Moreover, emerging MCC models and services are discussed, and challenging issues are identified that will need to be addressed in future work.

A Survey of Energy Efficient Wireless Transmission and Modeling in Mobile Cloud Computing

The emergence of mobile cloud computing (MCC) indicates that increasingly abundant applications are available, thus deeming energy problems even more significant. To achieve energy optimization in mobile systems, power consumption involved with each component or application need to be estimated prior to execution. In this paper, we present a survey on the universal energy estimation model for mobile devices. Additionally, due to the significance of wireless network interface card (WNIC) in the power use of mobile devices, considerable researches have been devoted to a low-power design of the WNIC (i.e., Cellular and WiFi). These efforts have allowed us to provide a comprehensive summary of recent work on transmission energy savings. Finally, we conclude the survey and discuss the future research directions.

Toward Advanced Mobile Cloud Computing for the Internet of Things: Current Issues and Future Direction

Cloud computing is the coming new era of information processing and has proved its benefits in high scalability and functional diversity. However, almost all cloud-computing architectures including SaaS, PaaS, and IaaS are vulnerable to serious security issues. Similarly, Mobile Cloud Computing (MCC) is vital to overcoming mobile limited storage and computing capabilities. MCC authentication and authorization issues must be provided on two levels: login password control and the environment from where the cloud is accessed. MCC has overcome the barrier of limited storage by providing remote storage but requires a strict security system that is responsible for retrievability, integrity, and seamless storage access. Elasticity and connectivity are also of major concern in MCC because delays and jitters cause degradation in the user experience. Cloud-computing architecture creates more challenges in maintaining security because of the liberty of users to choose any MCC architecture. Thus in this paper we discuss current cloud computing issues and future directions.

Future Directions in Electronic Computing and Information Processing

We are facing a slowing down of the evolution of microprocessor performance. This is part of a more general slowing down which is indicated by, among others, the fact that IBM has recently given up its PC market. By applying the principles of physics, we discuss some characteristic features of the current situation and consider if some exotic new technologies such as nanoelectronics or quantum computing would be able to save us from this slowdown.     

Future Directions for Mobile Communications Business,Technology and Research

This paper presents a picture of the mobile communications market and expected further development of systems and technologies. This is done with evaluating the market needs and reflecting these to available technology as well as technological opportunities. Despite of apparently advanced state of the technology and business, both market and technical solutions are concluded to likely experience further radical changes. The need for wireless capacity is two orders of magnitude more than what combined 2G and 3G would provide. A meaningful research objective to achieve is not in any single topic but will emerge from combining the needs of market and society with the opportunities offered by plurality of technologies. This opportunity starts form explorations aiming to a deeper understanding of the spatial propagation effects and ways to deploy them.
