Domain-partition (DP) model is a general model for reliability maximization problem under given redundancy. In this paper, an improved DP model is used to formulate a reconfiguration computing based fault tolerant system which is self-repairable in case of failure, and is solved as a nonlinear planning problem. The assumptions made in previous work are(More)
Aimed at the needs for scheduling real-time tasks in the environment of open real-time system and embedded system, a scheduling mechanism based on messages has been suggested and applied on the Xen virtual machine, and a Multi-Real-Time-Task model based on VCPU is established. Influence on the real-time scheduling is analyzed and solutions will be given.(More)
Based on the Ethernet and Bluetooth wireless technology, an improved Bluetooth Ad Hoc network structure, WBPAN(Wireless Bluetooth Personal Area Network) is proposed for the streaming media distribution. In WBPAN, each Bluetooth AP acts as the root of the Bluetree and connects with the nearby Bluetooth devices by the modified BlueTree formation algorithm. In(More)
With the development of science, remote data visualization is playing an increasingly important role. Meanwhile working on the road is becoming the life style of modern society. However, handicapped by the limits of the mobile embedded device and mass data to be visualized, the remote data visualization for mobile clients is still a big challenge. In this(More)
Transducer network plays an increasingly important role in the world. It has more and more functions while facing a lot of challenges such as inconvenient deployment when the scale is larger and larger. The transducer network introduced in this paper can be deployed automatically and has the ability to sample simultaneously in distributed devices. To(More)
