Mobile devices are ubiquitous but their resources are limited. However, they must be capable to run computationally intensive software, for example for image stitching, face recognition, and simulation-based artificial intelligence. As a solution, mobile devices can use nearby resources to offload computation. Distributed computing environments provide such features but ignore the nature of mobile...
Mobile and wearable devices are nowadays the de facto personal computers, while desktop computers are becoming less popular. Therefore, it is important for companies to deliver efficient mobile applications. As an example, Google has published a set of best practices to optimize the performance of Android applications. However, these guidelines fall short to address energy consumption. As mobile software...
The human daily and the professional life demand a high amount of communication ability, but every fourth adult above 50 is hearing-impaired, a fraction that steadily in- creases in an aging society. For an autonomous, self-condent and long productive life, a good speech understanding in ev- eryday life situations is necessary to reduce the listening ef- fort. For this purpose, a mobile app-based...
As the number of mobile devices that natively support ad hoc communication protocols increase, large ad hoc networks can be created not only to facilitate communication among the mobile devices, but also to assist devices that are executing computationally intensive applications. Prior work has developed computation offloading systems for mobile devices, but this work has focused exclusively on offloading...
In the latest years, we observed an exponential growth of the market of the mobile devices. In this scenario, it assumes a particular relevance the rate at which mobile devices are replaced. According to the International Telecommunicaton Union in fact, smart-phone owners replace their device every 20 months, on average. The side effect of this trend is to deal with the disposal of an increasing amount...
The world of mobile devices which have the quality to stay connected to the web is going through a exponential growth, but in parallel with this event, appears the threats with the developing of an equal magnitude, which are segmented primarily by the characteristics of the target device, therefore, as an final user is very difficult to know how exposed it is to use or purchase one of these devices...
The number and variety of applications for mobile devices continue to grow. However, the resources on mobile devices including computation and storage do not keep pace with the growth. Incorporating the computation capacity on cloud servers into mobile computing has been desired. However, there are numbers of challenging issues to realize it. In this work, we design and implement an elastic computation...
Web accessible services on mobile devices such as smart phones and tablets are a reality in today's age. Services hosted on mobile devices consume valuable device resources such as battery power, network connectivity, and Global Positioning Systems (GPS) availability. For this research, clients consume web accessible services, provisioned from mobile devices acting as service providers. A challenge...
Currently, we can observe the growing of the use of mobile devices as a media for both Internet access and carrying out purchase and sale of products and services. Commonly, E- commerce platforms are enabled by either proprietary systems or by buying ads on specialized websites. This scenario involves the adoption of strategies based on e-commerce servers, which represent a non-scalable strategy....
The number of mobile devices and the amount of mobile traffic are increasing rapidly. The users of mobile device use various services such as web surfing, email, video and audio streaming, etc. Analyzing mobile traffic is necessary to provide high quality mobile network services such as QoS management, traffic engineering, etc. In fact, several multi-flow applications consume a lot of mobile network...
Today's computationally able mobile devices are capable of acting as service providers as opposed to their traditional role as consumers. To address the challenges associated with the development of these mobile services, we have developed Odin, a middleware which masks complexity, allowing rapid development of mobile services. Odin, however, does not allow cross-platform development, which is an...
This paper shows the importance and benefit of coupling cloud computing with mobile especially due to power limitations that mobile devices exhibit. Moreover, the work done shows that mobile computing can be applied for educational purposes, where a tool for students termed Mobi4Ed is presented. This educational tool aims at exploiting the concept of cloud computing in the context of image and video...
The Vital Responder project aims at exploring the synergies between wearable technologies, scattered sensor network, intelligent building technology and precise localization services to provide secure, reliable and effective first-response systems in emergency scenarios. One of the components required in this technological setting is the ability to monitor biosignals from first responders in the field...
The Chinese input problem is essential to multimedia mobile device. After introducing the basic concept of Android system, characteristics of Android are analyzed. A realization of Chinese input based on Android with C language is proposed in this paper, and a corresponding new method which can improve the performance of the input method is raised. The experimental results show that this new method...
For the traditional surveillance system with the weakness of over-reliance on monitor environment, poor mobility and so on, this paper proposed a monitoring scheme based on android smart phone terminal. By collecting and processing data at server, sending data to smart phone terminal via socket, it reaches the purpose of monitoring the target site anywhere and anytime under the coverage of wireless...
Dramatic increase in smartphone sales and third-party applications that users can download has significantly increased the possibility of rootkits and malware targeted for smartphones. This paper discusses the current state of research in detection and mitigation of propagation of malicious code, such as viruses, malware and even rootkits in smartphones. A new strategy is introduced that offers a...
The recent development in mobile technologies has increased the demand for sophisticated software applications for mobile devices. This technological-driven market evolution poses new opportunities and challenges for developers to create applications which will fully exploit mobile's new and expanding capabilities. In this article, we investigate the mobile application development by providing possible...
In this paper we use Android application development interfaces and Eclipse IDE development environment, design and develop the electronic dictionary application based on a new generation of intelligence mobile Google platform Android. The English words' import, retrieve, add and delete function are simulated through a virtual machine Dalvick. We simulate the design through Sharp SH905i mobile. The...
As mobile devices have become more powerful and pervasive, mobile computing has become more important. As the market share of mobile operating systems steadily grows and more IT applications are developed and deployed on mobile devices, this will become a larger and increasing part of professional IT practice. Consequently IT students should gain experience creating and deploying mobile applications...
The hand-held systems and the wireless Internet access are widely available in recent years. However, the mobile learning with web content is still inconvenient. For example, the information has not well organized and it is uneasy to surf on the small screen of handheld device. We propose a mobile system based on the content of Wikipedia. Wikipedia is a free content resource and has abundant contents...
