ABSTRACT In this work, we present a analytical hierarchy process (AHP) for computing trust in the vehicular ad hoc networks (VANETs). AHP based trust management provides a lightweight security alternative to existing security techniques. Trust Management in VANETs is required to broadcast of selfish or malicious messages and also enable other vehicles to filter out such messages. A trust management system has ability to cope with sparsity of direct interactions. To evaluate the trust, we introduce the AHP based technique constitutes the combination of direct, reputation and indirect trust technique. The AHP is also used to coalesce various recommendation opinions from neighbour vehicles through exchanges of messages. Result shows that the scheme is lightweight and completes in order of milliseconds.
