Routing is a standout amongst the most imperative difficulties with respect to portable unplanned nodes (MANETs). Having no fixed framework nodes with continuous topology changes, require routing conventions to work under participation of all nodes. In case, lack of co-operation of the node will reduced the performance and also leads to denial of service. Uncooperative conduct of nodes can result in form of attack against the network. One of the destructive attacks of MANET which will reduce the performance of the network is Black Hole Attack. The work of black hole attack is to deviate the network traffic towards the fake node and to drop the received data packets. In this paper we would like to analysis about Black hole attack in one of the proactive routing protocol namely optimized link state routing (OLSR) protocol.
