MITIGATION OF BLACK HOLE ATTACK USING GENERIC ALGORITHMS AND FUZZY LOGIC

A black hole is a node that always responds positively to every PREQ, even though it does not really have a valid route to the destination node. Since a black hole does not have to check its routing table, it is the first to respond to the PREQ in most cases. There are two sorts of black hole attack could be defined in AODV with the purpose of differentia te the type of black hole attack. At present, several efficient routing protocols have been proposed for VANET. Most of these protocols assume a trusted and cooperative environment. However, in the presence of malicious nodes, the networks are vulnerable to various kinds of attacks. In VANET, routing attacks are particularly serious. So, this proposed work tries to design and implement fuzzy and GA algorithm with Black hole attack in AODV and prevent the system for threat using this hybridization.
