Dynamic Trust Applied to Ad Hoc Network Resources
نویسندگان
چکیده
The Dynamic Trust-based Resources (DyTR) system applies a dynamic notion of trust to ad hoc network resources. DyTR continuously assesses the trustworthiness of entities over time based on system events and controls network resources according to current levels of trust. For dynamic trust assessment, DyTR utilizes a socio-cognitive model of trust, a formal model of the essential concepts and characteristics of trust in human society, and subjective logic for reasoning about trust-relevant system events. We describe a DyTR experiment in which trust assessment is coupled with resource delegation mechanisms in a simulated dynamic network environment.

Contributions à la sécurité dans les réseaux mobiles ad Hoc. (Contributions for the Security in Mobile Ad hoc Networks (MANETs))
The thesis focuses on security in Mobile Ad hoc Networks (MANETs) [RFC 2501]. The lack of any central management of the network functions make MANETs more vulnerable to attacks than wireless (WLANs) and wired networks (LANs). Unfortunately, security protocols that currently exist are not designed to adapt MANETs characteristics. They do not take into account the resource limits, while the envir...

Ad hoc mobile networks have dynamic topology with no central management. Because of the high mobility of nodes, the network topology may change constantly, so creating a routing with high reliability is one of the major challenges of these networks .In the proposed framework first, by finding directions to the destination and calculating the value of the rout the combination of this value with ...

متن کاملEstablishing Trust In Pure Ad-hoc Networks
An ad-hoc network of wireless nodes is a temporarily formed network, created, operated and managed by the nodes themselves. It is also often termed an infrastructure-less, self-organized, or spontaneous network. Nodes assist each other by passing data and control packets from one node to another, often beyond the wireless range of the original sender. The execution and survival of an ad-hoc net...

An ad hoc network is a group of wireless mobile hosts that are connected momentarily through wireless connections in the dearth of any centralized control or some supporting services. The mobile ad hoc network is at risk by its environment because of the vulnerabilities at channel and node level. The conventional security mechanisms deals with only protecting resources from unauthorized access,...
