A Novel Reputation Model for Trusted Path Selection in the OLSR Routing Protocol

Models based on the concept of trust and reputation are widely used for securing routing protocols in self-organizing networks. The paper considers existing approaches to secure the OLSR routing protocol and identifies their drawbacks. Based on the existing approaches, we proposed a new Boolean-valued reputation model, a trust-based routing metric and an algorithm for finding the most trusted paths from a single source to all destinations. The proposed model was implemented as an extension of the OLSR routing protocol in ns-3 network simulator. Some results of simulation tests are also presented in the paper.
