Mobile devices provide computing power for running software applications as well as cell phone functionality. However, they could not host complex software applications, mainly due to their limited resources. This limitation can well be remedied by architectural design. We provide taxonomy with six different architectural patterns; standalone, full offloading, partial offloading, SaaS-based, CaaS-based,...
This research is concerned with the utilization of mobile devices as a tool for learning (m-learning). Therefore, approaches in developing learning applications that can suit the small screen size and restrictive capabilities of the devices are studied so that they can help the learners in understanding the concepts being delivered from the applications. This paper presents the study of design principles...
Mobile Social Network Service has been broadly researched on nowadays, however few people tries to explain the essence of MSNS, which leads to no common architecture for MSNS system. Consequently, in this article we compares the Mobile Social Network Service (MSNS) with the Social Network Service (SNS) in several aspects and present a perspective on future vision of mobile social network by analyzing...
This paper presents a proposal of software architecture to assist in the development of Virtual Reality applications for mobile devices based on context adaptation techniques. The aim of this solution is to offer support to Virtual Reality context appropriateness to be used by different mobile devices in accordance with their individual limitations. This adaptation is dynamically performed by the...
In order to meet the greater than ever before integration and consolidation needs, enterprises are migrating towards SOA-based models. Besides, driven by the dissemination of more refined mobile devices in the enterprise, and the rapid growth of wireless networks based on IEEE 802.11 WiFi Standards, mobile applications have been increasingly used in mission-critical business applications. The SOA-based...
Information seeking is getting more difficult, because there is too much information on the nets. In order to increase the accuracy of searching results, a user must possess information skills, such as Boolean logic: “and”, “or” etc. He also needs to know when to use general search or blog search to get more suitable results. Unfortunately, not everyone has these skills. In this research, a searching...
Mobile devices as the iPhone and Android-based smartphones can be turned into useful tools for researchers in the field. The concept of a scholarly or scientific workbench can be extended by a mobile usage scenario, where the researcher takes photographs, records sounds, and performs basic metadata editing. We present the prototype and the architecture of a mobile workbench that uploads geo-tagged...
The Web services technology has been emerged as a set of standards for publishing, discovering, and composing independent services in an open network. While the rapid development in wireless communication technologies is greatly changing the way people access and work with information. Mobile computing system based on Web services now supports advanced methods for application integration through distributed...
This paper develops a client-side context-aware search application which is built on the context-aware infrastructure. A context-aware architecture is designed to collect the mobile user's context information, derive mobile user's current context, distribute user context among context-aware applications, and support the context-aware applications. The context acquisition is centralized at the context...
The evolution of wireless networks and mobile devices has resulted in increased concerns about performance and security of mobile payment systems. In this paper we propose SA2pMP, a lightweight secured architecture for two-party mobile payments. SA2pMP employs a lightweight cryptography scheme that combines public key and symmetric key cryptography systems (ECDSA and AES), as well as a multi-factor...
Peer-to-peer content-distribution networks are nowadays highly popular among users that have stationary computers with high-bandwidth Internet connections. Mobile devices (e.g. cell phones) that are connected to the Internet via cellular-radio networks, however, could not yet be launched into this field to a satisfactory extent. Although most mobile devices have the necessary hardware resources for...
The automotive infotainment industry is currently pressured with many challenges. Tier-one manufactures must accommodate disparate and quickly changing features for different carmakers. Moreover, the use of a dedicated platform for each brand and model is no more viable. The use of an open platform would permit sharing costs across the whole customer spectrum, and it will allow products to grow and...
To support m-commerce applications such as mobile e-auctions, an efficient service discovery mechanism is required in a scenario where service directories are stored on distributed servers and users are mobile. E-auction services discovery in dynamic mobile environments poses many challenges such as dynamism in E-market, service access time, service filtering, lack of automated tools for searching...
The security of mobile operating systems becomes more and more important with the increasing number and increasing use of mobile devices. With the advances in operating systems security new concepts are introduced for increasing the security of current mobile operating systems. This paper introduces a testing system for the platform security architecture (PSA) of the mobile operating system Symbian...
Multimedia information systems have been developed into service-ware. With the paradigms of web services, service oriented architectures (SOA), and Web 2.0 widgets, multimedia has become truly ubiquitous. However, interoperability, scalability, reliability and security are arising challenges at mobile multimedia service development. This paper focuses on the analysis, design, development and evaluation...
Creation of pedagogical learning models to handle the specificity of mobile learning and the inherent constraints of mobile devices is a fundamental challenge in mobile learning. In this paper, we propose a generic semantics-based service-oriented architecture (SOA) and show how ontologies, when used together with Web services, can provide mobile users with a fresh learning experience. The proposed...
This paper presents research and development of dedicated system architecture, designed to enable its users to interact with each other as well as to access information on points of interest that exist in their immediate environment. This is accomplished through managing personal preferences and contextual information in a distributed manner and in real-time. The advantage of this system is that it...
In the mobile-learning the reduced functionalities of the mobile devices must be integrated with the typologies of the services delivered to the student. By referring to the Remote Didactic Laboratory Laboratorio Didattico Remoto - LA.DI.RE. ldquoG. Savastanordquo the delivered services taken into account are: experiment visualization, experiment control, and experiment creation. In order to enable...
In pervasive environments, users can potentially access a variety of services through their mobile devices. However, in order to use the new services, we need to adapt the functionality of these devices. To achieve it, we propose to load a bootstrap into them that is able to communicate with the services. However this bootstrap has to be adapted due to the diversity of services offered in the environment,...
