A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. In MANET, Ad-hoc On-Demand Distance Vector (AODV) floods the control packets to discovery the route. Generally there is a limit on the number of these packets that can be generated or forwarded. Malicious node can disregard this limit and flood the network with fake control packets so that these packets have the limited bandwidth and processing power of genuine nodes in the network while being forwarded. Due to this, genuine route requests suffer and many routes either do not get a chance to materialize or they end up being longer than otherwise. This paper presents a simulation analysis of reactive routing protocol AODV in the presence of malicious attack under different Load. We present the simulations results based on packet delivery fraction, throughput, normalized routing load, and packet loss.
