All the way through cooperative behaviour of the vehicular nodes information dissemination in VANETs occurs. Vital information like traffic jam, emergency brake procedures, road conditions, accident warnings, bad weather conditions, etc are messages transmitted in vehicular network. Misbehaviours and false hindering is a serious issue in VANET if any vehicles maliciously send messages. Deviation from the average behaviour of other vehicular nodes in the Consecutively to make VANET a secure network, detection of misbehaviors and the malicious vehicular nodes concerned in such misconducts is tremendously imperative. In this paper we have proposed a message broadcasting and message priority assignment in vehicular networks to resolve this problem. Initially the messages are prioritized using SMTP metric. we are using the three levels of priority's those are emergency, general request and entertainment request and then finally secured information transaction via., optimal blowfish algorithm based signcryption technique. The performance of the proposed algorithm is analyzed with existing techniques.

Abstract


All the way through cooperative behaviour of the vehicular nodes information dissemination in VANETs occurs. Vital information like traffic jam, emergency brake procedures, road conditions, accident warnings, bad weather conditions, etc are messages transmitted in vehicular network. Misbehaviours and false hindering is a serious issue in VANET if any vehicles maliciously send messages. Deviation from the average behaviour of other vehicular nodes in the Consecutively to make VANET a secure network, detection of misbehaviors and the malicious vehicular nodes concerned in such misconducts is tremendously imperative. In this paper we have proposed a message broadcasting and message priority assignment in vehicular networks to resolve this problem. Initially the messages are prioritized using SMTP metric. we are using the three levels of priority's those are emergency, general request and entertainment request and then finally secured information transaction via., optimal blowfish algorithm based signcryption technique. The performance of the proposed algorithm is analyzed with existing techniques.
