In this paper, we propose a novel QoE-driven centralized scheduling framework to satisfy the differentiated quality of experience (QoE) requirements of cellular users for HTTP-based video streaming transmission. The framework jointly considers the comprehensive information from the video server side (video coding rates and QoE parameters), the user side (video playback buffer occupancy), and the time-varying...
The spatial information of the video sequence is introduced into the background modeling process to deal with the problems of the traditional single-pixel based mixture of Gaussians moving objects detection method. Gaussian modeling process is improved to adaptively select the number of models, learning rate and other parameters by adjacent neighborhood pixels updating, spatio-temporal smoothing and...
With the emergence of network virtualization, the infrastructure can be effectively integrated to overcome the "ossification" of the Internet. The biggest challenge in network virtualization is the problem of virtual network embedding. Unfortunately, most of the researches on virtual network embedding only focus on static algorithms, which allocate fixed or invariable resources to virtual...
A novel structure of dynamic model is proposed in this paper and applied to construct a dynamic model to correct the dynamic errors of the infrared thermometer, because of which the dynamic performance of the thermometer is effectively improved. The dynamic compensator is established and the compensation is described and explicated by the Wiener model. According to Wiener model, the novel structure...
