A novel spectrum defragmentation scheme based on service priority is proposed to reduce the blocking probability according to the concept of spectrum compactness in spectrum-efficient optical networks. Numeric results show its good performance.
In order to measure the quality of cloud services better, this paper proposes a measurement method, which mainly measures the quality of cloud services from two aspects: availability and performance. At the same time, it introduces a measurement framework based on plug-in. The framework can collect service information and calculate the quality of cloud services with the measurement method. It can...
A teleoperation system of Internet-based Multi-Operator Multi-Mobile-Manipulator is proposed in this paper. The system consists of master sides and slave side, which has the characteristics of mobility, cooperation, distribution, fault tolerance, redundancy etc.. In master sides, with the aid of Distributed Virtual Environment and multi-video image, operators use the haptic interface device to control...

In this paper, we present a semantic model to represent spatiotemporal information for Web pages. Most Web pages in the real world are related to time and locations, thus our purpose is to enhance the traditional search engines with the ability of expressing spatiotemporal predictive. For this purpose, we need to extract the spatiotemporal information of Web pages into a formal representation structure...
