Secure communications by tit-for-Tat strategy in vehicular networks

Abstract

Secure communication is one of the main challenges of ad hoc Vehicle Networks (VANET). Intrusion detection of malicious nodes is one of the solutions to secure communication in VANETs using hybrid architecture (V2V and V2I). This article proposes an approach based on game theory, in particular the “Tit-for-Tat” (TfT) strategy as a suitable paradigm for human cooperation in order to detect malicious nodes in passive and active attacks. This article analyzes the performance of the proposed approach and the “TfT” strategy contribution in VANET security.
