Simulation And Analysis Of Performance Parameters For Black Hole And Flooding Attack In MANET Using AODV Protocol

As the increase of wireless networks, use of mobile phones, smart devices are gaining popularity so the adhoc network is also a uprising field. Each device in a MANET is free to move independently in any direction, linking to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router.. This paper describes the features, application, flooding attack and black hole attack in the MANET implemented on AODV protocol. The simulation work is carried out in Network Simulator (NS2.34). The performance analysis is done for 3, 5 and 10 nodes. The average delay, routing overhead, packet drop rate and packet delivery rate are calculated. By the simulation it has been evaluated that in flooding attack the routing overhead is more as compared to the black hole attack. A comparative study is also done on these parameters for all three scenarios.
