Real-time video communications has been incorporated into many instant communication tools such as ichat, Skype, QQ, etc. Real-time video communications has low delivery delay requirement, which imposes great challenge to the provisioning of such services. To address this problem, in this paper, we propose a selective redundant transmission mechanism to support real-time streaming on multi-interface...
With the technology of "Internet plus" gradually penetrating the energy industry, the fusion of smart grid and other energy network is now forming, which will create a new generation of high-efficiently energy utilization system called energy internet. And its complex coupling between energy flow and information flow is being to a cyber-physical system that possesses new features, i.e.,...
With the popularity of the Internet, the extension speed of network resources always lags behind the demands of network bandwidth of network users. It is not an omnipotent solution to increase the available bandwidth. That is why it is important to analyze, control and manage network traffic accurately nowadays. It is reported that, as one of the prominent occupants, peer-to-peer (P2P) traffic takes...
Video transmission over Internet is often afflicted by various packet losses. The packet-lever forward error correction (FEC) is often used for error recovery in order to enhance the end-to-end video quality. However, the quality metrics used in traditional FEC scheme designing such as peak signal-to-noise ratio (PSNR) have been founded not correlate well with human perceptual quality and usually...
With the penetration of the Internet and the rapid development of information technology, the secure transmission of the text and image herewith gets a great deal of attention. The traditional methods of encryption can only maintain the information security. However, the information could be cracked and to proceed criminal acts by the illegal use of the relevant information. Therefore, it is necessary...
Personal objects in Netnews oral reviews are important component of public opinion. Recognition of personal objects is the base of sentiment analysis for oral reviews. This paper analyzes the characteristics of personal objects in Netnews oral reviews. Based on these characteristics, we present an efficient recognition approach. The approach firstly evaluates reliability of one Chinese character as...
The goal of information extraction (IE) is to find the specific information from documents composed by natural language for a particular scenario. With the development of IE methodologies, a lot of information extraction tools have been proposed and are playing an important role in information processing. However, the efficiency of these tools may not be satisfactory to users. One of those important...
One of the great challenges in Internet service fault management under noisy and uncertain environment lies in the difficulty of fault priori distribution acquisition. To address the problem, an active probing based approach is proposed for the Internet service in this paper. A hidden Markov model(HMM) based dynamic probabilistic dependency model is chosen to be the fault propagation model (FPM)....
With the information explosion causing by the World Wide Web in recent years, the issue of how to execute the enormous information efficiently at a reasonable lost has become the concern of information providers, service agencies and end users. When many research focus on how to design an efficient Web crawler, we pay our attention to how to make the best of the result of Web crawler. In this paper,...
As the Internet rapidly becomes one of the most important information medium, Web information mining has been the focus of several recent research projects and papers. There are massive documents in certain formats on the Internet while Web crawlers building up with millions of computers scratch the Internet pages every second. Why not combine these two efficiently? This paper describe a new thought...
As an outcome of the overwhelming volume of Internet resources, it is necessary to research methods integrating distributed autonomous resources connected to the Internet to make them more effective and efficient. With the understanding of characteristics of internet resources, this paper will focus on solving the problem of text resource aggregation in open environment and its emergence showed during...
The next generation Internet is expected to consist of different wireless networks with diverse performance. Given the complementary characteristics of 3G and WLAN, the combination of 3G and WLAN can achieve anywhere, anytime Internet access and bring benefits to both end users and service providers. For this purpose, an efficient vertical handoff (VHO) algorithm is needed to make intelligent handoff...
