Abstract :
For secure VANET communication first system has to discover who the attackers are and how they can damage the VANET communication. Attackers disturb the communication by getting full or partial access in communication of network. Based on the participation nature of attackers we can detect the different attackers. VANET communication must be secure and must having surety that transmitted message is not inserted, deleted or modified by any attackers. Detection of such attackers will only give improvement up to some extent, but there is a need to identify a method which prevents such attackers before spreading attack in other VANET communication areas. In this paper we presented the analysis of hybrid preventive approach PAODV_RTPSN (Preventive AODV - Reactive Trusted Path based on Sequence Number). We presented the improvement of hybrid method under blackhole routing attack with the detail comparative analysis of different parameters like Packet Drop Rate, Throughput, Average End to End Delay, Jitter and Network Routing Load
