Wireless Sensor Network is a heterogeneous system combining tiny sensors with general purpose computing elements. Although many different routing protocols have been proposed for Wireless Sensor Network, most of which do not take security into account seriously. Routing attacks can have devastating effects on Wireless Sensor Network and present a major challenge when designing robust security mechanisms...
In order to improve the robustness and recovering capability of the Web service, the fault diagnosis becomes the key technology in the Web service management. On the basis of analyzing the features of the Web service fault, this paper proposes a Web service fault taxonomy that combines the Web service type with the implementation process and constructs a Web service fault tree. Meanwhile, this paper...
The worm experimental environment is the pivotal foundation for the worm research. Existing methods to build the environment, such as mathematical modeling, simulation and emulation, almost all of the existing methods inherently face a rigid fidelity-scalability tradeoff problem. Aming at this issue, this paper proposes a novel virtual-reality hybrid worm emulation model based on our network emulation...
The measurement of worm propagation impact on network status remained an elusive goal. This paper analyzes the worm characteristics and network traffic and service, introduces evaluation metrics and presents a new method to assess the network situation under worm propagation. The applicability of this method is verified by simulated experiments with the network simulation tool LSNEMUlab test bed.
The worm experimental environment is the pivotal foundation for the worm research. Existing methods to build the environment can be classified into three categories: mathematical modeling, simulation and emulation. However, almost all of the existing methods inherently face a rigid fidelity-scalability tradeoff problem. Aming at this issue, this paper proposes a novel virtual-reality hybrid worm emulation...
