This study seeks to look into deployment of open source virtual learning environments, such as Moodle, for developing country situations using Malawi as a case study. The study makes specific focus on mobile devices with a specific focus on mobile phones. Mobile access to learning environments is an innovative way to use mobile networks to increase access to education. This is also in line with the...
When disasters occurs, cellular network might be down and cannot serve subscribers anymore. On the other hand, many victims trapped in a wreckage might still have access to their mobile phone. An OpenBTS-based cellular network has been long before known as an ideal solution to rapidly deploy emergency GSM cellular network in situation after disaster. The problem arise when victims' mobile phone only...
With the increase use of Android mobile phones, more Android malwares are being developed. Android malware detection becomes a crucial task. In this paper, we present a permission-combination-based scheme for Android malware detection. The Android malware detection scheme is based on permission combinations declared in the application manifest file. We obtain the permission combinations that are requested...
Recent threats caused by worms on mobile phones are recognized as one of the most serious security threats to heterogeneous networks. Some early work model assumes that worm propagation on mobile phone cannot infect Computer in the Internet, or vice versa. However, as the development of mobile phone and multiply approaches surfing online, such as 3G, Wi-Fi, itputs hybrid nodes (mobile phone and Computer)...
In this paper, we have developed the digital frame multimedia player based on mobile network server. Sending photos taken by mobile phone, the image data is stored on the mobile network server of mobile communication operators and transfer into the digital multimedia frame interconnected with the network sever. At this point, the digital multimedia frame to the network operators should be up to the...
In this work we use anonymous telecommunication data to investigate how migration influences the dynamics of mobile social networks. We analyze the evolution of social ties for an entire country over a period of 11 months, examining: tie strength, sociality level, distance of ties, and persistence of ties. We find changes in tie strengths pre and post migration, specifically at six months before and...
This paper presents a smart home computing platform architecture that extends smart home network to be compatible for smart grid integration. The proposed hardware architecture along with a tailored software algorithm empowers utility companies and homeowners to communicate bi-directionally with home appliances via a public mobile network to monitor and manage power consumption of home appliances...
Recent mobile device and vision technology advances have enabled mobile Augmented Reality (AR) to be serviced in real-time using natural features. However, in viewing augmented reality while moving about, the user is always encountering new and diverse target objects in different locations. Whether the AR system is scalable or not to the number of target objects is an important issue for future mobile...
We describe a multi-agent based context-aware mobile educational game that can generate a series of learning activities for users doing on-the-job training in their working environment. In this paper, we reveal the multi-agent architecture (MAA) that is designed in the mobile educational game. The multi-agent architecture design enables development of a lightweight, flexible, and scalable game on...
In this paper, a new mobile Augmented Reality (AR) framework which is scalable to the number of objects being augmented is proposed. The scalability is achieved by a visual word recognition module on the remote server and a mobile phone which detects, tracks, and augments target objects with the received information from the server. The server and the mobile phone are connected through a conventional...
With the improvement of living standards, shopping malls are bigger after constructing with more abundant goods and more variety of wares. Therefore, building a simple, fast and convenient shopping guide system has become a mutual concern of merchants and customers. In view of the mobile phone has become a popular consumer products, a simple optimization method was given to design shopping guide system...
The growth in numbers and capacity of mobile devices such as mobile phones coupled with widespread availability of inexpensive range of services presents an unprecedented opportunity for mobile health care applications. Blood donation and transfusion service is one of the most complex management systems in health sector. Quality management of a Blood Transfusion Services (BTS) starts with safe blood...
Ubiquitous computing technologies have been developed fast and various decision support systems were proposed. Consecutively, in recently, people are working on an implicit service agent of mobile phone to make people to be provided useful services without paying attentions. However, when people want to buy some products or to go somewhere, people are still going to use Internet to get preference...
Mobile phones have been diffusing worldwide at an astonishing rate. They provide individuals with unprecedented connectivity to information and inter-personal interaction, and thus are expected to enhance social capital. This paper sets out to present an investigation focusing on the impact of mobile phone use on individual social capital. Based on the case studies conducted in Australia and South...
Thanks to the Internet development, a surveillance user can monitor the distant events via a browser on a computer. These events can be even viewed on a mobile phone with the assistance from modern mobile networks. Besides, two well-known platforms - OSGi and OpenCV are widely used for application construction. OSGi is constructed to provide a service platform with high application interoperability...
With mobile commerce technology continuously being taken more into use and introduced in new markets, the transition to mobile commerce (m-commerce) will make mobile shopping exceedingly popular. In the near future mobile shopping will probably replace today's markets or shopping complex. This project presents a mobile application which is built using Mobile Information Device Profile (MIDP) of the...
Peer-to-peer based content sharing is considered as one of the most efficient and popular content distribution solution nowadays. However in such network it is common that parts of the content is not distributed to several peers yet, thus during the download we have to wait a lot for that rare pieces. In addition to that it is also possible that we will not be able to download the rare pieces because...
Some constraints imposed on the design of components for mobile devices are the size of the handheld device, safety for handling, heat dissipation, and in-system electromagnetic interference. This paper discusses challenges in designing the next generation low power DRAM subsystem operating at multi-gigabits per second. A new mobile DRAM interface that can meet the challenges and some test data are...
This paper presents a cross-platform solution of smartphone-based mobile sink for wireless sensor networks, named uSink. With a cross-platform SD card, named uSD card, any smartphone with SD interface can be empowered with the capability to communicate with wireless sensor nodes. Furthermore, a middleware on mobile phone, named uSinkWare, is also designed to provide a typical mobile sink's functionalities,...
