Managing trust in a distributed Mobile Ad Hoc Network (MANET) is challenging when collaboration or cooperation is critical to achieving mission and system goals such as reliability, availability, scalability, or reconfigurability. In defining trust and managing trust in a military MANET, we must consider the interactions between the composite cognitive, social, information and communication net...

In this paper, we present a trust-based framework for message propagation and evaluation in vehicular ad-hoc networks where peers share information regarding road condition or safety and others provide opinions about whether the information can be trusted. More specifically, our trustbased message propagation model collects and propagates peers’ opinions in an efficient, secure and scalable way...

In mobile adhoc netwotk (MANET), a node’s quality of service (QoS) trust represents how much it is reliable in quality. QoS trust of a node is computed based on its multiple quality parameters and it is an interesting and challenging area in MANETs. In this work, QoS trust is evaluated by taking into consideration quality parameters like node residual energy, bandwidth and mobility. The propose...

Trust propagation is a fundamental topic of study in the theory and practice of rankingand recommendation systems on networks. The Page Rank [9] algorithm ranks web pagesby propagating trust throughout a network, and similar algorithms have been designed forrecommendation systems. How might one analogously propagate distrust as well? This is aquestion of practical importance and...

Trust and reputation measures are crucial in distributed open systems where agents need to decide whom or what to choose. Existing work has overlooked the impact of an entity’s position in its structural graph and its effect on the propagation of trust in such graphs. This paper presents an algorithm for the propagation of reputation in structural graphs. It allows agents to infer their opinion...

In this paper, we discuss one possible way of establishing trust between a user entity and a web service. We will assume that the user entity is machine-based (i.e. some software, a mobile agent or even perhaps a web service). After a brief introduction, we will consider the concept of Trust and the Web Services framework in two separate sections. In the case of Trust, we will show that two asp...

A theoretical visual interaction framework to model consensus in social network group decision making (SN-GDM) is put forward with following three main components: (1) construction of trust relationship; (2) trust based recommendation mechanism; and (3) visual adoption mechanism. To do that, dual trust propagation is investigated to connect incomplete trust relationship by trusted third partner...

In this paper, we propose a facilitator which finds capable and trustworthy partners on behalf of client users, which helps users form and maintain e-partnerships for electronic commerce and electronic collaboration. Unlike existing capability-based facilitators or matchmakers, the facilitator collects and maintains private “wordof-mouth” trust information as well as capabilities from each user...

Recent drastic advances on the mobile technologies and the network infrastructure have enabled kinds of new cyber spatial services to substitute for the various existing offline activities. The Social Network Services can be considered the most conspicuous one of these services and it has been propagating day by day in virtue of the expansion of the mobile internet devices. Even though this typ...
