In this paper, we have discussed the problem of black hole attack in VANET using OLSR routing protocol. 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. So, this proposed work tries to design and implement fuzzy and GA algorithm with Black hole attack in OLSR and prevent the system for threat using this hybridization.
