CTS: A Credit based Threshold System to Minimize the Dissemination of Faulty Data in Vehicular Adhoc Networks

چکیده
In VANETs, vehicles broadcast messages to other nearby vehicles to exchange information among them about their surroundings. This broadcasting of messages may enhance road safety and traffic efficiency, which is possible only if the messages announced are true and could be relied upon. However, the presence of faulty and malicious messages in the network may lead to greater security threats. This paper proposes an approach called Credit based Threshold System , termed “CTS”, to minimize faulty data dissemination in vehicular network to improve the security and reliability of the network. The CTS approach uses two of the most common and efficient techniques to achieve the property of message reliabilitythe Threshold method and the Credit-based model. Both these concepts are integrated together to design an approach that mainly focuses on message authentication. The main idea is to check for the authenticity of the message, so as to ensure the message being truthful and reliable; and consequently, reduce the propagation of malicious and faulty messages from the network. A message with a higher value of authenticity is accepted and rest are discarded. In this paper, we have also proposed, a formula for message authentication.
