WSN is a very essential topic for research nowadays and it is used in many basic to critical applications like military operations, Health Analysis, etc. So, Security becomes a very important parameter in WSN for transferring data from one location to other. It is very difficult to keep an eye on every node in the Network because it depends upon the size of the network. To maintain the normal flow of data it’s very prominent to keep sensor nodes secure from all the threads coming into the network. Small changes in the network data can degrade the network's performance metrics depending upon the attack type that happened, active or passive. A blackhole attack is introduced in this paper, which attracts the flow from the source with fake routing information given to the source. The source sends the data without knowing that the destination is an attacker and can drop the selected packets or all the packets. If the attacker drops only the selected packets it’s very difficult to detect this attack. In this paper, blackhole attack and its influence is stated in the result analysis using AODV protocol with and without attack as the 7 nodes are taken into the consideration for the simulation. Results are the same as expected that there is a huge impact on WSN when this attack comes into play and is described in the graph.
