The Mobile Ad hoc Network, also known as MANET, is continuously self-configuring without any infrastructure. The communication between nodes in MANET is insured directly without any intervention of fixed equipment or specific administration, due to mobility in MANET, each node has a role to insure the communication between the source and the destination, it considers both as host and router by using specific routing protocols. There are many routing protocols destined for ad hoc network. OLSR (Optimized Link State Routing Protocol, considered as proactive MANET protocol that keeps track of destinations in a routing table. OLSR uses new concept called by MultiPoint Relay (MPR). The goal of MPR nodes is to avoid blind flooding retransmission of routing packets; OLSR routing protocol is vulnerable to several attacks that reduces its performances. The Black Hole is the most routing attack known in literature, in our paper we evaluate OLSR routing protocol under two types of Black Hole attack; the single and the cooperative Black Hole attack. The measurements are taken in terms of throughput, Packet Delivery Ratio (PDR) and Packet Lost (PL). Simulation is done by Network Simulator (NS-3.25).
