The major challenge faced by wireless sensor networks is security. Because of dynamic and collaborative nature of sensor networks the connected sensor devices makes the network unusable. To solve this issue, a trust model is required to identify malicious, selfish and compromised nodes. It supports the decision making processes in wireless sensor networks such as pre key-distribution, data aggr...

Dynamical and flexible resource aggregation tools are required in 21 century research. Scientists need to aggregate various digital equipments and cooperate with each other in different organizations through Virtual Organizations (VO) on the Internet in a flexible and dynamical way. In this cooperation and resource sharing process, trust evaluation is of great importance for flexible VO managem...

The major challenge faced by wireless sensor networks is security. Because of dynamic and collaborative nature of sensor networks the connected sensor devices makes the network unusable. To solve this issue, a trust model is required to find malicious, selfish and compromised insiders by evaluating trust worthiness sensors from the network. It supports the decision making processes in wireless ...

The aim of the study was to investigate the association between contextual generalized trust and individual-level 2009 A(H1N1) pandemic immunization acceptance. A second aim was to investigate whether knowledge about the A(H1N1) pandemic mediated the association between contextual generalized trust and A(H1N1) immunization acceptance. Data from the National 2009 H1N1 Flu Survey was used. To cap...

In peer-to-peer (P2P) environments, a peer needs to interact with unknown peers for the services provided. This requires the trust evaluation prior to and posterior to interactions. This paper presents Trust: a novel and dynamic peer trust evaluation model, which aims to measure the credibility of peers’ recommendations, and thus to filter noise in responses and obtain more accurate and objecti...

Direct trust relationship is the foundation of research on the indirect recommendation trust between agents and the global trust degree. In view of the lack of analysis and attention on the direct trust in the current research of dynamic trust relationship, this paper proposes a minimum variance time sequence weight based direct trust aggregation algorithm which is constrained by the fuzzy inte...

Trust is not only essential in our daily lives, its importance in virtual networks should not be underestimated either. For example, we only use information found on the web when we trust the source, and we do not give our credit card details on sites we distrust. With the advent of the semantic web [2], intelligent web agents will be taking over more and more human tasks. Therefore, there is a...

Ratings (also known as recommendations) provide an efficient and effective way to build trust relationship in the human society, by making use of the information from others rather than exclusively relying on one’s own direct observations. However, it is uncertain that whether the rating can play the same positive effect in the open computing environment because of differences between the compu...

The range of applications of wireless sensor networks is so wide that it tends to invade our every day life. In the future, a sensor network will survey our health, our home, the roads we follow, the office or the industry we work in or even the aircrafts we use, in an attempt to enhance our safety. However, the wireless sensor networks themselves are prone to security attacks. The list of secu...
