In trustworthy service discovery for Mobile Social Networking in Proximity (MSNP), conventional trust computation faces a big challenging issue—relatively high latency. To cope with it, trustworthiness determination strategies were proposed in our previous study, aiming at avoiding trust computation under certain conditions, so as to reduce the latency. These strategies are conceived based on the...
With the rapid development of mobile networks, people are no longer limited to seeking information offline. The Internet provides a good choice for them. As the previous research work shows, more and more people get used to using the Internet to search for health information. Online health information has attracted much attention ever before. It is well known that health related information generated...
With the popularity of mobile Internet, smart phones and location-based services, Mobile Social Network in Proximity (MSNP) has attracted more and more attentions, for which trustworthy service discovery and its associated latency are two important issues. In this paper, after overviewing MSNP and trustworthiness for service discovery in MSNP, we discuss the major issues and potential solutions of...
In this study, we propose an integrated approach to organize and refine the social streams in accordance with the analysis of both social data and social roles within a social group. The social stream data will be first collected and organized based on users' individual needs. After the calculation and analysis of users' importance based on the identification and classification of users' dynamical...
With the high accessibility of the social media, more and more people have been accustomed to sharing their personal contents across the social networks, which results in an explosive increase of data scale. In this study, in order to support information and knowledge discovery in big data, we propose an approach to aggregation and integration of personal big data from life logs in accordance with...
Identifying design patterns from source code is one of the most promising methods for improving software maintainability, reusing experience and facilitating software refactoring. In this paper, an approach that combines static and dynamic analysis on detecting design patterns from java source code is presented. Static structure analysis of identifying pattern instances is illustrated. Especially,...
Wireless Sensor Networks(WSNs) bring together many applications and disciplines to capture the most intensive economical development of the century. The objective of this paper is to provide a snapshot of the trust-based security mechanism for WSNs. Three kinds of trust information are summarized. After analyzing the security problems and brief reviewing of the trust management for WSNs, a comparing...
This paper investigates using lexical cohesion to generate a moderately fluent semantic summary from a collection of documents written in Chinese. Based on the algorithm of cohesion analysis using the relationship among the words in the HowNet knowledge database, the built system computes concept frequency rather than word frequency as a measurement of importance. It merges the analysis of lexical...
Recently, new technological advances in biosensors, micro electro mechanical systems (MEMS) and wireless communications have enabled the design of low-cost, miniature, lightweight and intelligent physiological sensor nodes. These nodes, capable of sensing, processing and communicating one or more vital signs, can be seamlessly integrated into wireless body sensor network for health monitoring. Using...
How to provide reliable transmission over unreliable links in sensor networks is an interest challenge. In this paper, a novel nodes-cooperation strategy in network layer for reliable transmission over unreliable-links is studied. The key idea of the proposed strategy is that using multi nodes to receive packets simultaneously and relay packets competitively. It is based on the observation that the...
