Application of trust-metrics for evaluating performance system in ad-hoc networks with privacy

Ad-hoc networks are usually constructed with a lot of nodes managed by unknown users and have a vague reliability level. In order to establish a reliable connection with the target node, users somehow need to evaluate the nodes and connection paths as correctly as possible. One of the solutions to this problem is to employ the trust-metrics to the node-and-path evaluation of the ad-hoc network. The trust-metrics are mainly used to evaluate the reliability (validity) of the public-keys of unknown users, e.g. in PGP. We, however, point out that there are some drawbacks when applying the ever known metrics to the node-and-path evaluation of the ad-hoc networks. We show that they are either low privacy - high utility or high privacy - low utility. To overcome these disadvantages, we propose the realization of high privacy high utility trust metrics and its application for evaluating the node´s performances in ad-hoc networks (electronic power consumption, transmission speed, etc).
