Most traditional alarm systems cannot address security threats in a satisfactory manner. To alleviate this problem, we developed a high-confidence cyber-physical alarm system (CPAS), a new kind of alarm systems. This system establishes the connection of the Internet (i.e. TCP/IP) through GPRS/CDMA/3G. It achieves mutual communication control among terminal equipments, human machine interfaces and...
Cyber-physical system (CPS) integrates physics with Internet to provide a timely, confidential and efficient interaction of physical appliances with people. However, as a CPS Application, Smart Home still has difficulties in building a centralized interaction for remote monitoring. The paper presents the interaction model of Smart Community Cyber-Physical System (SCCPS) with the name Net-in-Net. The...
This paper presents a web-based remote process control engineering laboratory for engineering education using configuration software. A set of double holding water tanks apparatus, suitable for remote control experiments, was carefully designed for process control experiments. A series of experiments from characteristics testing of one order process to predictive control of nonlinear system can be...
Adaptive video is a popular technique to continuously deliver a video stream to a user in the best quality possible when the underlying network bandwidth cannot be guaranteed. As such, quality of adaptive video depends critically on the agility of the rate adaptation algorithms in tracking the varying bandwidth. In this paper, we investigate the performance of a popular rate adaptation algorithm,...
In this paper, the authors have demonstrated a principle to capture the strong correlation of location and WWAN network bandwidth in the form of bandwidth-road maps.The authors demonstrated how these maps can be used to intelligently schedule traffic in a multi-homed mobile network. Preliminary results show that this approach can effectively improve the user experience of on-board audio streaming.
Botnets have been recognized as one of the most important threats to the security of the Internet. They engage in Distributed Denial of Service (DDOS) attacks, email spamming and other malicious activities likewise. As evolving new features such as decentralized architecture, using P2P networks and etc, new Peer-to-Peer(P2P) botnets could no longer be indicated effectively and accurately by using...
Botnets have been recognized as one of the most important threats to the Internet security. They are engaged in DDOS attacks, email spamming and other malicious activities likewise. Traditional botnets usually organized themselves in a hierarchy architecture, which offers professionals opportunities to detect or defend the botnets in their servers. However, newly-appeared P2P botnet such as Storm...
A research topic that is becoming increasingly popular is that of on-board mobile communication, where users on a vehicle are connected to a local network that attaches to the Internet via a mobile router and a wireless link. However, wireless data transmission is less efficient, prone to error and unreliable in a mobile environment. There is a need to make use of multiple access links simultaneously...
