Environment-Aware Reputation Management for Ad Hoc Networks

Download Now Free registration required

Executive Summary

Reputation management is a mechanism that has been proposed to mitigate against internal node misbehavior with respect to the packet forwarding functionality in ad hoc networks. Their goal is to promote cooperation among nodes by building a reputation for each and utilizing that reputation in offering differentiated services to different nodes (e.g. prioritizing packet relaying based on the reputation of the source). It has been customary to carry out the functions of reputation management (evaluation of node behavior, detection of misbehaving nodes, and reaction to nodes according to their behavior) homogeneously across time and space.
