A Low-Energy Fast Cyber Foraging Mechanism for Mobile Devices

The ever increasing demands for using resource-constrained mobile devices for running more resource intensive applications nowadays has initiated the development of cyber foraging solutions that offload parts or whole computational intensive tasks to more powerful surrogate stationary computers and run them on behalf of mobile devices as required. The choice of proper mix of mobile devices and surrogates has remained an unresolved challenge though. In this paper, we propose a new decision-making mechanism for cyber foraging systems to select the best locations to run an application, based on context metrics such as the specifications of surrogates, the specifications of mobile devices, application specification, and communication network specification. Experimental results show faster response time and lower energy consumption of benched applications compared to when applications run wholly on mobile devices and when applications are offloaded to surrogates blindly for execution.Comment: 12 pages, 7 figures, International Journal of Wireless & Mobile Networks (IJWMN

Supporting and Securing Personal Mobile Devices Within an Existing Information Technology Environment

Personal mobile devices are becoming integrated into the daily operations of business. Managers are realizing that employees who are allowed to use personal mobile devices to access corporate information systems may reduce costs as users buy their own devices. The problem was that managers have a limited understanding of the need to secure or support personal mobile devices. The purpose of this survey study was to examine the relationship between employees\u27 desire to use personal mobile devices and corporation needs for security and support. Hypotheses were tested by examining the relationships between the requirement to support and secure personal mobile devices as the independent variables and the desire to use personal mobile devices as the dependent variable. The theoretical framework for the study included the IT product life-cycle management theory, IT security-management theory, and IT strategic-management theory. Survey data were collected from a convenience sample of 108 employees at the study-site organization from an estimated population of 170. Basic linear regression analyses performed found a correlation coefficient of 0.905 indicating the variables are highly correlated. This finding indicates that if personal mobile devices are given access to corporate information systems, then support and security will be necessary for successful operations. If the relationship between internal factors and operational success is clearly documented, organizations may be able to use the data to justify incorporating personal mobile devices within their own corporate information system to reduce costs, improve productivity, and increase employee satisfaction, thereby making a positive contribution to society
