Analysing Performance Disruption of MANET Under Explicit Flooding Attack Frequency

The number of routing protocol is available in Mobile Ad hoc Networks (MANETs), but none of them is perfect as it is hard to achieve the security in it. The MANETs is in vulnerable of different attacks because the network is scalable and has very dynamic mobile nodes. The performance of protocols is severely affected in the presence of malicious nodes as these causes routing information to be erroneous and introduces excessive traffic load and inefficient routing. In this paper, we analyse the network performance extensively using Ad hoc On Demand Distance Vector (AODV) routing protocol in the presence of a flooding attack with specific frequency rate. The NS2 network simulator is used to analyse this flooding attack on AODV and its impact are shown using various performance metrics like Packet Delivery Ratio (PDR), throughput with variable flooding rates and malicious nodes etc.
