Mobile Computing in Physics Analysis - An Indicator for eScience

This paper presents the design and implementation of a Grid-enabled physics analysis environment for handheld and other resource-limited computing devices as one example of the use of mobile devices in eScience. Handheld devices offer great potential because they provide ubiquitous access to data and round-the-clock connectivity over wireless links. Our solution aims to provide users of handheld devices the capability to launch heavy computational tasks on computational and data Grids, monitor the jobs status during execution, and retrieve results after job completion. Users carry their jobs on their handheld devices in the form of executables (and associated libraries). Users can transparently view the status of their jobs and get back their outputs without having to know where they are being executed. In this way, our system is able to act as a high-throughput computing environment where devices ranging from powerful desktop machines to small handhelds can employ the power of the Grid. The results shown in this paper are readily applicable to the wider eScience community.Comment: 8 pages, 7 figures. Presented at the 3rd Int Conf on Mobile Computing & Ubiquitous Networking (ICMU06.

Mobile Game: A Multiplayer Mobile Game via Bluetooth Technology for Nokia Series 60

The Final Year Project developed is 'Mobile Game: A Multiplayer Mobile Game via Bluetooth Technology for Nokia Series 60'. The existing mobile games are mostly a stand-alone application, which means the game can only be played by a player. Even with the availability of multiplayer mobile games in the market, the maximum number ofplayers of those games is two. The objective of this project is to study and develop a multiplayer (specifically three players) mobile game with Bluetooth technology as the connection means. The first part of this project would be the research and study pertaining to the development of multiplayer mobile game for three players using Bluetooth technology. The second part of the research pertains to the downside of Bluetooth technology and recommendations to improve the situation. The methodology used is the combination of waterfall and prototyping model. A mobile game application is produced as the end-product of this project. Meanwhile, the findings discover the details on the end-product development and also some discussion design issues and challenges as well as limitationof Bluetoothtechnology

Marine data collection based on embedded system with wired and wireless transmission

A great interest of boat manufacturers is to improve their products by knowing how the boats are used after sale. In order to gather information about the condition of usages, a system needs to be developed in order to collect data from different marine electronics mounted on the boat. Through this thesis work, we developed such data collecting system for leisure boats which support CAN Bus the message-based protocol. The data collection system has been developed and installed on a Linux-based embedded system connected to the CAN Bus network through a gateway in our laboratory. Through the data collection system, all data generated from different marine electronics in the network can be captured, filtered, transmitted, displayed and then stored in the system. For data transmission and access, we have implemented three methods through wired or wireless networks, i.e., the fixed Internet, 3G/LTE cellular networks and Wi-Fi networks. Furthermore, the prototype implementation has been extensively tested in both lab and real-life environment

Future Open Mobile Services

The major barriers for the success of mobile data services are the lack of comprehensible mobile service architectures, their confusing business models and the complexity combined with the inconsistency of the technology enablers. This paper attempts to present a more structured and comprehensive analysis of the current mobile service architectures and their technology enablers. The paper starts with a thorough study of the evolution of mobile services and their business models, and a collection of expectations of the different actors, including the end-user. Next, starting from the original mobile services architecture and environment, an attempt to place the different technology enablers in relation to each other and in relation to their position in the mobile system, will be carried out. Each technology enabler together with their contribution in the enhancement of mobile services are then summarised in a complete and comprehensive way. The paper concludes with a recapitulation of the achievement of the state-of-the-art technology enablers and an identification of future improvements

Web Tracking: Mechanisms, Implications, and Defenses

This articles surveys the existing literature on the methods currently used by web services to track the user online as well as their purposes, implications, and possible user's defenses. A significant majority of reviewed articles and web resources are from years 2012-2014. Privacy seems to be the Achilles' heel of today's web. Web services make continuous efforts to obtain as much information as they can about the things we search, the sites we visit, the people with who we contact, and the products we buy. Tracking is usually performed for commercial purposes. We present 5 main groups of methods used for user tracking, which are based on sessions, client storage, client cache, fingerprinting, or yet other approaches. A special focus is placed on mechanisms that use web caches, operational caches, and fingerprinting, as they are usually very rich in terms of using various creative methodologies. We also show how the users can be identified on the web and associated with their real names, e-mail addresses, phone numbers, or even street addresses. We show why tracking is being used and its possible implications for the users (price discrimination, assessing financial credibility, determining insurance coverage, government surveillance, and identity theft). For each of the tracking methods, we present possible defenses. Apart from describing the methods and tools used for keeping the personal data away from being tracked, we also present several tools that were used for research purposes - their main goal is to discover how and by which entity the users are being tracked on their desktop computers or smartphones, provide this information to the users, and visualize it in an accessible and easy to follow way. Finally, we present the currently proposed future approaches to track the user and show that they can potentially pose significant threats to the users' privacy.Comment: 29 pages, 212 reference

The cgml: a xml language for mobile cartography

Increasing processing power and storage capabilities encourage systematic adoption of high-end mobile devices, such as programmable cellular phones and wireless-enabled PDA to implement new exciting applications. The performances of modern mobile devices are bringing innovative scenarios, based on position awareness and ambient intelligence paradigms. The market is moving from old 'Wireless Applications' approach to Mobile Computing, which aims to exploit mobile host capabilities. This paper presents the compact Geographic Markup Language (cGML), an XML-based language defined to enable design and development of LBS applications specific for mobile devices, and an example of client-server architecture using it

Seamless mobility with personal servers

We describe the concept and the taxonomy of personal servers, and their implications in seamless mobility. Personal servers could offer electronic services independently of network availability or quality, provide a greater flexibility in the choice of user access device, and support the key concept of continuous user experience. We describe the organization of mobile and remote personal servers, define three relevant communication modes, and discuss means for users to exploit seamless services on the personal server
