Secure Route Selection Based on Trust Value for Distributed Networks

Secure route selection is always a challenge for distributed networks. The paper takes trust value as one of routing metrics for distributed networks to defense some attacks. The paper provides an algorithm to compute trust value and then gives a routing algorithm based on trust value. Trust value´s computation takes remembering factor and credibility as main parameters. The final route is secure and short. When routing message is back from the destination to the source, some malicious nodes could be found.
