    Cell phones and other mobile devices are used to access the Internet even at home and at work where computers are easily available. They are no longer a mere backup to the computer. This means that it makes little sense to study Internet access from mobile devices separate from other Internet access. We need new methods that encompass online behavior from desktop computers and mobile devices as well as stationary and mobile online behavior

    Mobile IP: state of the art report

    Due to roaming, a mobile device may change its network attachment each time it moves to a new link. This might cause a disruption for the Internet data packets that have to reach the mobile node. Mobile IP is a protocol, developed by the Mobile IP Internet Engineering Task Force (IETF) working group, that is able to inform the network about this change in network attachment such that the Internet data packets will be delivered in a seamless way to the new point of attachment. This document presents current developments and research activities in the Mobile IP area

    Mobile communication and the mobile Internet can provide important opportunities, economic advantages for enterprises end organisations and support their more efficient operating as they can be used anytime and anywhere. We can make their wide spread use, innovative effects and advantages economical if we consider the effect system of technologies and services. The technological, social and economical complex effect system puts a pressure on the spreading of business applications. The types of applicable equipment are increasing. The Internet technology and the Internet network have become essential communication tools in business processes recently. Using the Internet by means of mobile appliances increases the possibilities. By studying the business process the expenses, advantages, disadvantages can well be seen. Nowadays these applications are more and more successful in areas such as agriculture, different parts of the food industry, extension services, precision agriculture and logistics. It can be stated that the international and the Hungarian development tendencies of the mobile Internet, the RTD Programmes of EU help the wide-spread use of mobile services. The rapid development of the Hungarian domestic mobile market over the last years is the basis for the wide spread use of new broadband mobile services and applications. This system can contribute to the development of agriculture, enterprises and rural areas and can support production, commerce, services and product tracing. But for successful applications we have to consider the impact factors

We can make their wide spread use, innovative effects and advantages economical if we consider the effect system of technologies and services. The technological, social and economical complex effect system puts a pressure on the spreading of business applications. The types of applicable equipment are increasing. According to social aspects there are four player groups: manufacturers, enterprises, customers and workers. The Internet technology and the Internet network have become essential communication tools in business processes recently. Using the Internet by means of mobile appliances increases the possibilities. By studying the business process the expenses, advantages, disadvantages can well be seen.

    When Crowdsourcing Meets Mobile Sensing: A Social Network Perspective

    Full text link
    Mobile sensing is an emerging technology that utilizes agent-participatory data for decision making or state estimation, including multimedia applications. This article investigates the structure of mobile sensing schemes and introduces crowdsourcing methods for mobile sensing. Inspired by social network, one can establish trust among participatory agents to leverage the wisdom of crowds for mobile sensing. A prototype of social network inspired mobile multimedia and sensing application is presented for illustrative purpose. Numerical experiments on real-world datasets show improved performance of mobile sensing via crowdsourcing. Challenges for mobile sensing with respect to Internet layers are discussed.Comment: To appear in Oct.

    Assessing the benefits of Ajax in mobile learning systems design : a thesis submitted in partial fulfillment of the requirements for a Master of Information Studies at Massey University

    Today, mobile technology is rapidly changing our life with increasing numbers of services supported by mobile phones, including mobile Internet access and Web-based mobile learning. The growth of the wireless Internet technology opens new path for people to study in anytime and any location. Using Web-based mobile application to present learning resources for mobile learners is a challenge for developers, because the mobile Internet access performance over GPRS networks is often unacceptably slow. A new Web development model, Ajax, may help to address this problem. Ajax (Asynchronous JavaScript and XML), is a new desktop approach to Web application development that uses client-side scripting to provide a seamless user application experience and reduce traffic between client and server. In this paper, we address the question of whether mobile Ajax provides measurable performance advantages over non-Ajax mobile learning applications. A real-life Web-based mobile learning application performance over a GPRS network study was done based on comparing an Ajax application and an Active Server Pages (ASP) application with identical functionality. Our results suggest that mobile Ajax can reduce the bandwidth requirement by 71%, and cut the server's response time in half. In addition, these performance improvements were noticed by users in our small group usability test
