What is Trust-Based Routing Protocols

Chapter 18
Handbook of Research on Threat Detection and Countermeasures in Network Security
Trust-based routing protocols are protocols that only accepts nodes with a trust above a certain minimum acceptable trust (MAT) in their routing table and use them for forwarding control/data packets, so that each node to be part of the routing table, it should have a trust above a certain MAT.

Abstract
Wireless ad hoc networks are susceptible to attacks by malicious nodes that could easily bring down the whole network. Therefore, it is important to have a reliable mechanism for detecting and isolating malicious nodes before they can do any harm to the network. Trust-based routing protocols are one possible mechanism as they locate trusted routes dynamically to conform to network environment. However, such algorithms require reliable and effective trust determination algorithm. This chapter presents a detail description and evaluation of the trust determination algorithm, namely, the Neighbor-Weight Trust Determination (NWTD) algorithm. The performance of the algorithm is evaluated through simulation using the Mobile Ad hoc Network (MANET) simulator (MANSim). The simulation results demonstrated the effectiveness and reliability of the algorithm in isolating any maliciously behaving node(s) in a timely manner.
