A notable requirement of heterogeneous parallel and distributed computing systems is to maximize their processing performance and agreed upon QoS. Lots of work in this field has been done to optimize the system performance by improving certain metrics such as reliability, robustness, security, and so on. However, most of them assume that systems are running without interruption all the time and seldom...
The goal of a video conferencing system is to deliver multimedia data to the conference participants efficiently and securely. To meet the requirement of a video conferencing system over the internet, many issues have to be addressed, such as security, scalability and heterogeneity. In this paper, we propose a secure and scalable video conferencing system named VCNF (Video Conference Network Foundation),...
A novel secure solution for remote access is proposed. Compared with the previous methods such as dial-up and vpn, our solution CSGW-RAS is quite new at using SSL for data transfer and GNU/Linux pseudo network device for data forward. It offers two important types of properties. One is security, which includes confidentiality, IP assigning and authentication, etc. We compare CSGW-RAS with IPSec VPN...
More attention has been paid to congestion control in the emerging area of wireless sensor network (WSN). However, most research works in the past stayed at the level of algorithm design or modification, and seldom sought solutions on the viewpoint of architecture. In this paper, Active Networking (AN) technology is used to make congestion control more responsive to detect/recover congestion in WSN...
