Along with the rapid development of 3rd generation mobile communication technologies, the applications of M-Commerce have been greatly expanded. Based on the research and analysis of the J2ME platform, this paper proposes a secure architecture for M-Commerce systems under the 3G networks. The proposed solution is the combination of J2EE and J2ME capabilities based on the three-tier architecture, as...
Recent advances in mobile wireless networks allow handheld devices, such as smart phones, pocket PCs, to connect to the Internet and use the distributed applications conveniently. And the model of software as a service enables the handheld devices to use the applications which previously run on PCs or servers. However, the mobile wireless environment is dynamic and resource-limited. It needs an efficient...
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...
In recent years, security has become a major concern in ad hoc network technology. It has unique characteristics that make new challenges arise compared to its wired networks or traditional wireless networks counterpart. Due to these unique characteristics, the traditional intrusion detection techniques for wired networks and wireless networks are not well suited for ad hoc networks. In this paper,...
In recent years, integrating SIP with OSGi has become one of the important research topics in the communication between mobile and networked home devices. In this paper, the general architecture for combining OSGi and SIP is investigated and implementation issues with the communication middleware are discussed. The encapsulation of OSGi devices with SIP has been realized by the concept of "SIP...
