High reliability is always pursued by network designers. Multipath routing can provide multiple paths for transmission and failover, and is considered to be effective in the improvement of the network reliability. However, existing multipath routing algorithms focus on how to find as many paths as possible, rather than their computation or communication overhead.
A generalized Caputo fractional derivative definition is first proposed. Based on that, two comparison inequalities for scalar and vector nonlinear fractional-order systems are constructed, respectively. An example is provided to show how the tools be used to analyze the stability of nonlinear fractional-order systems.
A new controller design method is proposed to synchronize a class of fractional-order chaotic systems. The nonlinear terms are first divided into stability-related part and stability-unrelated part. And then the stability-related nonlinear terms are absorbed by the designed controller. Controllers designed according to this method have much simpler structures than those of existing results in literature...
In this paper, a novel variable-domain approach to curve evolution for image segmentation was proposed, being based on a statistical active contour model using level sets. The essential idea is to re-define the computing domain in image repeatedly, by separating the segmentation procedure into several individual phases, for images composed of an infinite number of regions. By our algorithm, the work...
Multihoming can enhance network reliability by utilizing the path diversity. In this paper, we put forward a new series-parallel diversity model (SPDM) based on AS rooted-tree based on multihoming model (MT model) and reliability model. Then, we define several metrics of path diversity and design correlative algorithm. By route views data, we carry out largescale experiment of AS path diversity based...
