As a most important part of students majoring in computer science related areas, experiments contribute to not only better understanding the theoretical knowledge but also enhancing the ability of hands-on. However, traditional laboratories require a high-cost investment on both site and equipment, especially experiments of computer network. In order to address these problems, we design a virtual...
The rapid development of intelligent terminals and mobile Internet industry has brought many challenges and opportunities to the mobile network. Mobile Network Open Services can provide users and developers with the open resources consisted of network infrastructure, network data and diversified services, so as to build an open, flexible, collaborative Internet ecosystem. The ability to open the mobile...
Experimenting in computer science course is challenging due to the limitation of site, equipment and special experiment tools. In this paper, based on the analysis of the experiments features of computer science curricula, such as, Principle of Computer Organization, Digital Image Process, Digital Signal Process etc., we design two kinds of virtual lab platforms and develop corresponding virtual lab...
Using a mobile device with embedded near-field communication, an agent-based software intelligence framework can make various applications in a pervasive computing environment more personalized, dynamic, and intelligent.
Protective measures for server invasions should not solely focus on events before an invasion occur. Recording and monitoring successful server invasions with endless streams of security mechanisms should be employed attentively to reduce the loss of data due to successful intrusion attacks on any system. Overlooking this will inevitably lead to detrimental data loss and stray away from the key issue...
Online user authentication using secure protocol is required by most web-based services. User authentication is mostly carried out by sending a pair of username and password to the server, since most users have not a certificate. Some attacks just rely on this fact, such as phishing attacks. In the paper, we discuss the issue of online user authentication and propose a method for online user authentication...
Multimedia broadcast/multicast service (MBMS) is an important part of the UTRAN evolution and supports downlink streaming and download-and-play type services to large groups of users. For enhanced MBMS (E-MBMS) under 3GPP long term evolution (LTE) system, there are two ways to transmissions being performed: multi-cell transmissions and single-cell transmissions. One requirement identified to be supported...
