Currently, mobile communications are provided convenient methods to explore and communicate with each other people. A multitude of services have converged on the smartphone platform, and potentially the most notable is social networking. Thus, the electronic Mobile Chat (MC) plays a very important role in the social networking. With the increasingly growing reliance on Mobile Chat System (MCS) in...
One of the most challenging limitations for the elderly and/or the visually impaired people is the inability of self-navigation in unfamiliar indoor environments. Numerous existing indoor navigation systems have been proposed in order to solve such problems. However, these papers do not adequately examine the effectiveness of the systems in real time trials and are faced with a variety of technical...
Social networking applications are changing the way people communicate with their peers and family. Social networking applications have several features that help in connecting one to another, from finding old friends to browsing for new friends and contacts. To harness the true power of social networking, sometimes it may be important to seamlessly identify and connect individuals who are geographically...
The college students are outstanding contemporary youth, and the universities are source of various social trend of thought. It is a big challenge for the college educational workers to cultivate the college students of healthy, upward characters. However, the traditional teaching methods cannot meet the requirements and get an expected result. To solve these problems, a cultural transmission platform...
In road networks, k-Range Nearest Neighbor (kRNN) queries locate the k-nearest neighbors for every point on the road segments that are within a given query region, based on the network distance. This is an important task, because the user's location information may not be accurate, furthermore, users may be unwilling to reveal their exact location for privacy reasons. Therefore, in this specific situation,...
Mobile users access location services from a location based server. While doing so, the user's privacy is at risk. The server has access to all details about the user. Example the recently visited places, the type of information he accesses. We have presented synergetic technique to safeguard location privacy of users accessing location-based services via mobile devices. Mobile devices have a capability...
Mobile applications are widely used in many research areas as well as in current daily life. Applications on smart phones are closely related to the physical device. An application may run differently on different mobiles. It is hard and expensive for college students to adapt and test their applications on several types of smart phones. This paper presents a work in progress on the development of...
This article focuses on the issue of the use of mobile technologies, especially on online Laboratories, as a support to professional development of adults in the work situation in Senegal. More specifically, how mobile learning can be a solution to access to education for nomadic professionals working specifically in the area of computer networks? This issue is at the heart of a doctoral research...
The keen adoption of m-learning by higher education institutions on a global scale because of widespread use of mobile devices requires proper security considerations in order not to expose m-learning systems to cyber-attack. M-learning systems normally comprise three components which are the mobile device, one or multiple servers and network devices. While servers and network infrastructure have...
Emerging large-scale distributed storage systems such as content delivery networks (CDNs) are faced with the task of distributing peta-bytes of requested data from mobile service users. In this paper, we present a novel cache architecture with enhanced performance that aims to reduce the data distribution load on CDNs for large-scale storage systems. Our proposed architecture is located between a...
While many virtual educational environments are already in use, few attempt to mix the virtual and the real worlds to a very high extent. The benefits of such approach could be groundbreaking, leading to new paradigms of education, however the complexity of the challenges and the scale of the effort are still very high. The "3D UPB" platform takes this approach of a fully mixed reality environment...
The rapid pace of change being witnessed globally in the Information and Communication Technology sector as well as the skyrocketing costs in getting basic education needs met have forced many to seek for alternative ways of meeting these needs. Recent innovations in distance education opened up the pathway to new and dynamic ways of learning through Massively Open Online Courses (MOOCs) aimed at...
Skyline queries are useful in decision making applications. Skyline queries in highly mobile distributed environments have attracted many attentions recently due to the development of mobile internet device. The properties of distributed computing make skyline queries more complicated especially in any subspace. Conventional skyline algorithms do not support subspace skyline queries in distributed...
Both in daily classrooms and at enterprises conferences, timely feedback from the audience and students are very important for chairmen or teachers. This will improve chairmen's or teachers' working and teaching efficiency in the interaction, because they can promptly know their audience's ideas and comprehension about the contents which they are describing. In this paper, we present software that...
The research study investigates the development approach and analyses of m-learning course management system developed as case study. The contribution of the research study is the analyses of the task based instructional strategy and conceptual definition of the assessment methods regarding the level of mobile learning outcomes while assessing different software engineering aspects of development...
In Thailand University, checking student attendance is one of the important issues for universities, because many universities evaluate students' attendance and while giving the final grade, professors consider their total number of appearances on classes during the whole semester. This brings to the idea of having some tool to control students' attendance. Some universities prefer to use paper sheet...
This paper mainly introduces the implementation of Real-time field survey using Android-based interface of mobile GIS network. Real-time field survey and ground truth was made readily available for GIS researchers back in an office while a survey team was reporting from the field via a mobile network. Both geographic data and geo- referenced remotely sensed image data are served from this site. An...
In our present day society, communication is rapidly becoming faster and more complex, with many new technologies in the communication field, people are finding it easier to communicate faster and more effectively with each other. Consequently it poses challenging risks if these are being used in surreptitious manner for planning and coordinating a crime. Therefore, this huge social network needs...
Since the contents stored in the web increases rapidly, we need to have an efficient search engine that retrieves the information as per the users interest and preference. So we propose a mobile search engine that personalizes users search with the help of the query that the user types and their click through activities. In mobile search engines location plays an important role, so we classify the...
Emerging new era of computing in fashionable trendy infrastructure to boot up a business perspective application services are provided through internet via the technological paradigm shift named as cloud computing. Furthermore cloud enhances the technological issues termed with mobile energy lifetimes and provides the better solution to save potential energy existence. Cloud plays the infrastructural...
