Africa is the fastest growing mobile phone market in the world. The portfolio of available mobile phone applications that impact the populations of the continent is however limited in number and scope. Future African graduates will be the main vectors for the development of mobile applications. In this paper we present a model of teaching mobile application development for social changes emphasizing...
This paper describes how a simple interactive mobile learning system, originally developed for the 2G system, evolved to a system for the 3G (TD-SCDMA) system, then to a system for the WiFi access system and finally become a generic Interactive Wireless Mobile Learning System which can be used in any wireless networks. The system designs in different stages of evolution are presented. To promote mobile...
In the past few years, many new mobile technologies including the 3G, WiFi or mobileTV have created unprecedented learning opportunities on mobile devices. Furthermore, such technologies continuously fuel the rapid growth of new fields of research like the edutainment for educational entertainment. In a recent project awarded by the Hong Kong Wireless Development Center, we have developed a mobile...
A variety of wireless access technologies provides todaypsilas users with pervasive access to critical content and applications. Guaranteeing a satisfactory quality of service requires reliable and ubiquitous delivery schemes that optimally use the available access technologies. This paper presents a novel architecture to support adaptive real-time data and multimedia applications over different wireless...
This paper introduces an approach to automatic synthesis of the specification models of routing protocol behavior from the observed flow of the network traffic. In particular, our technique generalizes the monitored sequences of routing messages constructing a high-level abstract view of the protocol. The basis of our method is similar to inductive logic programming technique that derives a sound...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
