In Mobile Ad hoc Network (MANET) mobile node is responsible for route establishment using wireless link where each node may behave like both as a host and router.MANET encounters number of security threats because of its open entrusted environment, with little security arrangement, security over MANET can be enhance up to some satisfactory level because of its inherent characteristics.Among some of the prominent security threats wormhole attack is considered to be a very serious security threat over MANET.In wormhole two selfish node which is geographically very far away to each other makes tunnel between each other to hide their actual location and give the illusion that they are true neighbours and attract other nodes to make conversation through the wormhole tunnel.Many researchers focused on detecting wormhole attack and its prevention mechanism.It seems that in the previous technique there is a need to improve their results in the brink of false negative rate, routing overhead etc.The present paper has proposed the hybrid model in order to detect and prevent the wormhole attack.This approach has been work with neighbour node and hop count method.
