Cache technologies are considered as the most favorable tools for dealing with the problems of wireless traffic flow, having attracted tremendous interest from both the engineering and academic fields. However, most of the algorithms and tools developed are essentially based on descriptive models instead of predictive models, which are not capable of processing content traffic in the optimal way for wireless users with strong social characteristics. In this paper, a novel social relation based cache distribution policy is proposed, by which not only interaction among network users is used to detect the influential users among them, but also inherent friend relationships are used to predict desirable contents. These features are utilized to assist cache distribution among caching servers in advance for the purpose of serving the future needs of wireless mobile users. Evaluation analyzes the realistic network dataset, and the simulation results demonstrate the superior performance of the proposed optimization framework over existing systems","PeriodicalId":14643,"journal":{"name":"J.

Through the knowledge sharing among the enterprises in the supply chain, the efficiency of knowledge innovation and application can be improved. In this paper, based on the state-of-the-art literature, the evolutionary game model of asymmetric upstream and downstream enterprises in the supply chain is built; the dynamic evolutionary process and the influencing factors of the selection of knowledge sharing strategies are analyzed. Based on those analysis, the results show that selecting knowledge sharing strategy in the upstream and downstream enterprises are affected by the factors: the cost coefficient of knowledge sharing, the risk coefficient of knowledge sharing, the gap between the amount of knowledge sharing of enterprises, which have negative correlation to selecting knowledge sharing strategy in the upstream and downstream enterprises; the coefficient of gains in social relationships, the synergistic effect coefficient of knowledge sharing, the incentive and punishment factor of knowledge sharing, which have positive correlation to selecting knowledge sharing strategy. On the basis of these factors, the concrete measures to promote knowledge sharing are put forward.

Although P2P technique has brought tremendous changes to the network technique, P2P technique also exposes a lot of problems during its implementation. If we can manage the P2P network traffic effectively,e.g. identifies and controls its traffic and distinguishes its services, then it will make great sense for research on improving the performance of network service and use efficiency. However,the traditional approaches have shown a great lack of adaptability in dealing with samples which contain heterogeneous information.large scale of samples,unnormalizeddata or uneven data distributed in high dimensional feature space. This paper is based on therelated researches, to overcomethe limitations and shortcomings of current network traffic identification; we explored network traffic identification and came up with an approach of network traffic identification based on random forest. This paper uses campus network of North China University of Water Resources and Electric Power and takes its outlet flow as sample data to experiment. The result shows that random forest is suitable for large scale of data situation, complex dimensional situation, data contain lots of heterogeneous information etc. Additionally, random forest algorithm provide broad application prospects and rich design ideas for machine learning in feature extraction, multiple class object detection and pattern recognition fields","PeriodicalId":14643,"journal":{"name":"J.

One of the most widely used anonymous communication systems is I2P(Invisible Internet Project). And as opposed to Tor’s(another popular anonymous communication system) directory-based approach, which provides a centralized directory server to manage the overall ‘view’ of the network, I2P is fully distributed and self organizing, which aims to avoid attackers’ enumeration of all I2P’s routers. In this paper, based on I2P’s operating mechanism, we presented two passive and two active methods to discover I2P routers. In a more than two week’s collecting experiment, about 25640 routers were discovered everyday, which turned out to be an almost full coverage(94.9%) of the I2P network compared with the data announced on the official website [1]. And based on the routers collected, this paper further made a preliminary analysis of both the I2P network’s overall status and its security. The result showed that I2P is a well structured P2P network, while some powerful attackers operating several routers are still possible to perform compromise attack to break I2P users’ anonymity given the current I2P’s security mechanism. Finally, this paper discussed some countermeasures to improve the security of the I2P network.","PeriodicalId":14643,"journal":{"name":"J.

Following the well-known modeling primitives, the scenario ontology is constructed on the basis of PROTON (Proto Ontology), the reference layer ontology of FactForge that includes some central datasets of Linked Open Data (LOD). The event module, scenario module and mitigation module comprise the core level scenario ontology, defined with some core concepts and relations, which can be reused in the domain level scenario ontology. Considering earthquake is a representative emergency, we analyze the scenario information required by decision makers in some earthquakes, and design the scenario ontology of earthquake as an example in the domain level scenario ontologies.
