QoS (quality of service) fluctuations caused by Internet bursty flows influence the user experience in the Internet, such as the increment of packet loss and transmission time. In this paper, we establish a mathematical model to study the influence propagation behavior of the bursty flow, which is helpful for developing a deep understanding of the network dynamics in the Internet complex system. To...
As one of the most popular topics in the Next Generation Network (NGN), Named Data Networking (NDN), a newly proposed network architecture centered on content data, targets on altering the existing communication protocol between Internet hosts. NDN uses data names rather than IP addresses for data transmission and re-designs the packet formats and the protocols between layers in order to substitute...
With the explosion of smartphone popularity in recent years, people are familiar with mobile tourism guides. Users often spend much time to look for travel information on the Internet without user interaction on relevant websites. Generally, the tour guides lead tourists to interact with travel attractions in a group trip. This study applies an interactive model to traveling while tourists join a...
This paper designs a new scheme based on Controlled Vehicular Internet Access (CVIA), a protocol that divides a straight road into several segments. To avoid hidden nodes and reduce unnecessary CTS/RTS, vehicles send the packet to the road side unit (RSU) segment by segment. The features of CVIA include its high end-to-end throughput and fairness between road segments. However, a significant problem...
Recent researches indicated that students' ability to construct evidence based explanations in classrooms through scientific inquiry is critical to successful science education. Structured argumentation support environments have been built and used in scientific discourse in the literature. To the best our knowledge, no research work in the literature addressed the issue of automatically assessing...
Nowadays, with the wide establishment of IEEE 802.11, more and more people use Wi-Fi to surf on the Internet. Due to the convenience and mobility of the mobile devices, a number of mobile users have been increasing greatly. For real-time video and VOIP have attracted much attention, the delay time of handoff is the most important issue for the service. In order to provide high-speed service with low...
With the deep penetration of the Internet, uncontrolled flood of information has become one of the most serious problems to Internet users. Harmful contents about pornography, violence and other illegal messages, etc have posed serious influence to the whole society, especially to the young people. In this paper, a novel Web text filter based on rough set and Bayesian theory is proposed to analysis...
Emergent computation is a relatively new approach for understanding the behaviors of complex systems. Central to this approach is the idea that system-level behavior emerges from interaction among individual elements. This paper proposes a network emergent computation model based on cellular automaton, which introduces network operating mechanism, such as store-and-forward, adjacency interaction,...
E-voting based on the Internet has been recently performed in a wide region. There isn't any spatial restriction that a voter has to go to a certain polling place, but an e-voting using the Internet has to gather the computer in which the internet connection is possible. This voting method requires an access account for the e-voting through the beforehand report of a voter. To minimize these disadvantages,...
The number of action devices is currently increasing. If the trade environments are not safe, both the development and the progress of electronic trade will be affected. As well as security issues, the handoff procedure incurs long latency and packet loss. Smooth handoff can not only lower the packet loss but also reduce the level of the out-of-sequence packets. So far, very little attention has been...
