In the cloud computing, the virtual machine (VM) dynamical management method needs to consider VM resource re-configuration caused by system computation resource status changing and load fluctuation. Based on migration objectives as QoS (Quality of Service), resource competition and energy...

Automatic modulation recognition is very important for the receiver design in the broadband multimedia communication system, and the reasonable signal feature extraction and selection algorithm is the key technology of Digital multimedia signal recognition. In this paper, the information entropy...

A common design of the Internet of Things (IoT) system relies on distant Cloud for management and processing, which faces the challenge of latency, especially when the application requires rapid response in the edge network. Therefore, researchers have proposed the Fog computing architecture,...

A Recommender System (RS) works much better for users when it has more information. In Collaborative Filtering, where users' preferences are expressed as ratings, the more ratings elicited, the more accurate the recommendations. New users present a big challenge for a RS, which has to providing...

In this article, the authors describe a client-server architecture, designed for supporting data recording and transmission during emergency patient transportation by ambulance. The clients are a set of mobile apps, interfaced to the monitoring devices in the ambulance, that automatically send...

There is an exponential surge in the number of Wi-Fi enabled devices which has caused an unprecedented overload on cellular and Wi-Fi networks. The two emergent techniques that have made significant difference in the reduction of network traffic surge are opportunistic communication and...

This paper explores the reasons millions of people use stand-alone, task-oriented software programs designed for use on mobile devices, commonly known as “apps.” This study uses a survey with a probability sample of 576 app users. Consistent with the uses and gratifications approach,...

Mobile devices have become a ubiquitous technology that are also inherently intertwined with modern society. They have enabled a revolution of how people engage and interact with technology, computing and the Internet. However, as their popularity has increased, so have the threats against them....

The voice-over-Internet protocol (VoIP) service is expected to be widely supported in wireless mobile networks. Mobile Broadband Wireless networks VoIP service to users with high mobility requirements, connecting via portable devices which rely on the use of batteries by necessity. Energy...

This paper proposes a robust hybrid-MAC protocol for direct communication among M2M devices with gateway coordination. The proposed protocol combines the benefits of both contention-based and reservation-based MAC schemes. The authors assume that the contention and reservation portion of M2M...
