Online reviews play a crucial role in helping consumers to make purchase decisions. However, a severe problem Internet Water Army (a large amount of paid posters who write inauthentic reviews) emerge in many E-commerce websites recently which dramatically undermines the value of user reviews. Although the word Internet Water Army originated from China, some other countries also suffered from this...
In aviation, Maintenance, Repair, and Overhaul (MRO) refers to the actions of fixing an air craft when it becomes out of order, or performing routine actions to keep the air craft in working order. MRO services are carried out strictly under the instruction of corresponding MRO task cards, which detail all the information including work content, procedure, equipment, etc. needed for MRO technicians...
This paper presents an optimistic fair exchange protocol based on public verifiable secret sharing for e-procurement applications in Peer-2-Peer networks. According to the decentralized feature of such a network, a distributed third party is designed to guarantee the fairness of exchange. Comparing to traditional trusted third party, this distributed third party is not fixed but dynamically selected...
Active queue management (AQM) mechanism plays an important role in network congestion control. In this paper, we propose an effective AQM algorithm, named adaptive real queue control (ARQC). In particular, an explicit congestion indicator, virtual regulating time, is designed to detect network congestion. Then by analyzing the queuing system on routers, we present the guideline to calculate the dropping/marking...
People are considered as important resources nowadays. When we are caught in some problem, how to find a direct or indirect friend, who is professional in the specific field, to help us is the key point. The popularity of social network provides a great platform for the solution of the problem through computer automation. Dijkstra is a classical algorithm for searching the shortest path between two...
Due to the challenging nature of nonlinearity and time-varying behaviors in TCP dynamics, traditional active queue management (AQM) algorithms suffer from poor robustness under dynamic network scenarios. To address the above problem, a novel congestion control scheme named FSM-AQM is proposed via the fuzzy sliding mode control, which is robust against uncertainties and time-varying parameters of the...
The concept of the Internet of Things provides a new model to access the information of the objective world. A new approach based on the Internet of Things for traffic emergent events is proposed. The network architecture entails a hierarchy of capability, information and control, where nodes in the network expected to possess resources for networking and computing and presume autonomy through multi-functional...
In business or in daily life, people are always faced with various chances and challenges. How to discover an emerging chance from some possible chances for decision making is still a problem for human beings to solve. This paper presents an effective method to deal with this kind of problem. Based on domain experts' experiences, the possible factors influencing chances are obtained. And then the...
After through the destructive strike of serious earthquake happened in Sichuan province had the mental health of people in disaster areas been downcast for quite a long time. To avoid this situation being worse, it's Post-Trauma Mobile Service (PTMS) that was launched and deployed to improve the status of people both in the physical and mental aspects. In this study, we will discuss a newly-issued...
Fast handover protocol provides seamless handover in mobile IPv6 networks by reducing handover latency. One assumption in fast handover is that the MN (Mobile Node) or the network could know or predict the new AR (Access Router) before data transport from the previous AR to the MN is disrupted. In order to achieve this capability, the complexity of predicting the new AR and the diversity of the wireless...
The main purpose of the educational resources grid is to share the educational resources located on grid nodes. Grid portal technology can meet this requirement, and it provides a manner to access grid resources with Web, which makes the use of the grid services much easy and convenient. As the result, based on a new Web framework-JavaServer Faces (JSF), this paper proposes a novel educational resources...
The 5.12 Wenchuan earthquakes has not only caused great loss of lives and properties of people in disastrous area, but also has brought profound psychological trauma to the victims. A post-trauma mobile service (PTMS) is developed and implemented in Sichuan province which combines the psychological counseling knowledge and mobile Internet technology. The PTMS service creates a new mode for long distance...
One of the major problems of deploying RSVP in the mobile environment is called the advanceresourcereservation problem. If an RSVP reservation path is reserved in advance in the subnet that a mobile node will visit, the mobile node can continue its QoS session smoothly when it hands over to that subnet. However, if too many network resources are used for advance reservation, new QoS sessions originating...
Service management is becoming more and more important within the area of IT service management. How to efficiently manage and organize service in complicated IT environments with frequent changes is a challenging issue. Service and the related information from different sources are characterized as diverse, incomplete, heterogeneous, and geographically distributed. It is hard to consume these complicated...
Acupuncture is the kernel of traditional Chinese medicine and is nowadays being accepted by the whole world. The precise orientation of the points and meridian is important in acupuncture while it is difficult to be done via the 2-dimension pictures. So the 3D interactive exhibition is undoubtedly superior to the traditional 2D way. A Web3D technology Cult3D and its advantages in contrast to VRML...
